The geometric variations of low-grade lumber raise concerns about bond strength of cross-laminated timber (CLT) produced from such lumber. This study seeks to investigate the effect of low clamping pressure and geometric variations of laminates on the bond strength of CLT. CLT panels were manufactured from low-grade grand fir (Abies grandis). Block shear tests and cyclic delamination tests were conducted on specimens randomly taken at specific points that correspond to a wide range of twist magnitude. Twist distribution in the lumber used as laminates in the CLT ranges from 0 to 160 mm. Results showed that twist magnitude and clamping pressure have significant effect on bond performance, with twist magnitude having an overriding effect on pressure.

This research evaluated the mechanical and physical properties of three underutilized hardwood species according to visual lumber grades. Findings are discussed in relation to the requirements recommended such as density, modulus of rupture (MOR), and modulus of elasticity (MOE) for the manufacture of cross-laminated timber (CLT) industrial mats, which is a potential end use of low-valued hardwood species. Results showed that all species tested had an average MOE greater than that required for CLT lumber. Visual grading was an important component in strength determinations as evidenced by the correlation between MOE and MOR. All grades of red oak (Quercus rubra L.) had higher densities than those of southern yellow pine, which is the traditional wood used in manufacturing CLT industrial mats, with a density of 616 kg/m3 at 12 percent moisture; the average density of the red oak tested was 770 kg/m3 at 13.98 percent moisture. All grades of red oak also had MOE and MOR values that met the requirements for lumber used in the manufacture of CLT industrial mats. For sweetgum (Liquidambar styraciflua L.), all grades met the required values for MOE and MOR, but only Grades 3 and 4 met the required density. All grades of yellow poplar (Liriodendron tulipifera L.) met the required MOE and MOR, but none met the required density.

Chinese-style chairs are appreciated by many consumers for their elegant design. The material and decoration have a significant impact on the design of Chinese-style chairs. Exploring the influence of these two factors on design styles and aesthetic expressions, as well as the related visual attention patterns, is of great importance for the design of Chinese-style chairs. This study aimed to investigate the impact of material (wood/metal) and decoration (pattern/no pattern) on the design style, aesthetic performance, and visual attention patterns of Chinese-style chairs. Fifty-six Chinese university students wore eye-tracking glasses to view four types of chair designs and completed subjective rating scales. The results show that material and decoration have both independent and interactive effects. Wood chairs exhibit a traditional design style and superior aesthetic performance compared to metal chairs. Traditional Chinese patterns enhance design style and aesthetic performance, particularly when applied to wooden chairs. Visual attention was not significantly different across chair designs, except for wooden chairs with traditional patterns on the backrest, which attracted more attention. These research findings provide reference for designers to design Chinese-style chairs.

The stability of a circular saw blade during the cutting process affects the knife life and the material utilization rate. In this article, continuous sawing experiments were carried out on medium-density fiberboard, Pterocarpus soyauxii board, and reconstituted bamboo lumber board. The temperature distribution of the saw blade surface was measured. The natural frequency of the saw blade under thermal stress was analyzed by the finite element method. The results show that the material density is positively correlated with the edge temperature of the saw blade. Greater temperature differences within the saw blade lead to worsening dynamic stability. When cutting the reconstituted bamboo lumber board, the saw blade will suddenly lose stability, and the surface temperature will rise rapidly, which greatly shortens the life of the saw blade.

Sustainable low-carbon design is actively guiding the public's green consumption and use of forest resources. With the slogan of replacing plastic with bamboo and the optimization of bamboo's organizational structure and processing form, bamboo is becoming more and more designable. However, we found that there are still many views expressing dissatisfaction with bamboo products, among which homogeneity and insufficient design differentiation are the most frequent. On the basis of this, we obtained attributes for measuring bamboo product satisfaction through literature review, conducted a questionnaire survey of 463 customers to obtain data, and empirically analyzed attributes such as product creativity (PC), product quality (PQ), product fashion (PF), soft added value (SV), and shopping convenience (SC). We assessed the impact on consumer satisfaction (CS), as well as the impact on satisfaction under the moderating effect of brand image (BI). The results show that PF, BI, PC, and PQ positively affect CS; PF, PQ, and SV positively affect the BI; PF, SV, and PQ positively affect CS through the intermediary effect of BI. SV has an insignificant effect on CS, but can positively affect CS through BI, indicating that there is a partial mediating effect of BI. However, the mediating effect of BI on PC, SC, and CS has not been verified. Finally, on the basis of the conclusions, several countermeasures and suggestions for bamboo product innovation are put forward.
可持续的低碳设计正在积极引导公众的绿色消费和森林资源的利用。随着 "以竹代塑 "口号的提出，竹材组织结构和加工形式的优化，竹材的可设计性越来越强。然而，我们发现，仍有许多观点对竹制品表示不满，其中同质化和设计差异化不足是最常见的问题。在此基础上，我们通过文献综述获得了衡量竹产品满意度的属性，并对 463 名顾客进行了问卷调查以获取数据，对产品创意（PC）、产品质量（PQ）、产品时尚（PF）、软附加值（SV）和购物便利性（SC）等属性进行了实证分析。我们评估了这些属性对消费者满意度（CS）的影响，以及在品牌形象（BI）调节作用下对满意度的影响。结果显示，PF、BI、PC 和 PQ 对 CS 有正向影响；PF、PQ 和 SV 对 BI 有正向影响；PF、SV 和 PQ 通过 BI 的中介效应对 CS 有正向影响。SV 对 CS 的影响不显著，但可通过 BI 对 CS 产生积极影响，这表明 BI 存在部分中介效应。然而，BI 对 PC、SC 和 CS 的中介效应尚未得到验证。最后，在结论的基础上，提出了竹产品创新的若干对策和建议。

The wood of African mahogany (Khaya spp.) is known for its high quality and similarity to the more expensive Brazilian mahogany (Swietenia macrophylla King). Interest in African mahogany has been increasing because of the reduced availability of native Brazilian mahogany, which has become illegal to harvest. Most African mahogany comes from managed plantations, so the increased consumption of this wood helps to alleviate issues related to illegal harvesting by reducing the trade of Brazilian mahogany. African mahogany has also been gaining popularity in the United States, particularly for use in the wood flooring market. However, there is lack of technical information on the properties of African mahogany material available in the US market, therefore, the objective of this work was to describe anatomical features, evaluate physical–mechanical properties and examine natural resistance of African mahogany wood that is commercially available in the US market. The results of this research provides an increase in knowledge on African mahogany wood properties, natural resistance, and provides technical information that is needed by industry.

As a material used in building construction, structural insulated panels (SIPs) deflect under flexural loading and creep over time. This work examines the deflection behavior of full-scale SIPs that were tested in bending. Approximately half of the matched specimens were tested after production and the other half were tested after a 90-day creep test. Of primary interest was the deflection behavior of the SIPs under load. After testing, the deflection was apportioned between the bending stiffness of the oriented strand board (OSB) and the shear modulus of the foam. Results indicated that when the known OSB modulus of elasticity values of 664,000 psi and 931,000 psi were considered among the different SIP thickness and treatments (with and without creep testing), the shear-based deflection from the foam ranged from 44 to 73 percent of the overall deflection. The calculated foam modulus of rigidity decreased slightly but significantly after creep testing. Also, the shear-based foam deflection increased slightly but significantly after creep testing.

The use of cross-laminated timber (CLT) has significantly grown in North America, but hardwood species have not yet been deemed a viable raw material for manufacturing CLT panels. Therefore, softwood species continue to serve as the only approved material for CLT in structural applications according to ANSI/APA PRG-320. Nonstructural CLT products that utilize low-grade lumber from hardwood species, are a good option for introducing hardwoods into the CLT market. Of the hardwood species located within Appalachia, northern red oak (Quercus rubra) is readily available. The purpose of this research was to develop hardwood cross-laminated timber mats utilizing low-grade red oak lumber. In order to manufacture red oak CLT mats, the best adhesive and bonding parameters had to be identified. Overall, sample CLT panels were made using three adhesives with nine different setups for each adhesive. The sample panels were processed into smaller blocks and separated for cyclic delamination and shear-block tests following the ANSI/APA PRG-320 standards. This research determined that a phenol–resorcinol formaldehyde (PRF) adhesive produced the lowest percentage of delamination, satisfying the delamination requirements. The PRF adhesive also produced the largest percentage of wood failure in shear-block testing, however, the results fell short of meeting the requirements. A Taguchi statistical analysis was used to predict the optimal bonding parameters for each adhesive. The optimized bonding parameters for the polyurethane (PUR) adhesive produced favorable results, indicating the delamination results have the potential to nearly meet the standard requirements, while the predicted shear results would exceed the requirements.

Using crushed hickory husks as raw materials, a single factor test was carried out on a hydraulic-plunger forming machine with different moisture contents and length–diameter ratios (LDRs) of forming mould in order to obtain biomass moulding fuel (BMF) briquettes. The moulding pressure in the forming mould was measured by the sensor, and the microstructures of the BMF briquettes were observed via stereomicroscope. Results showed that hickory husks could be compressed and formed into BMF briquettes at room temperature. When the moisture content of the raw materials was 14 percent and LDR of the forming mould was 4.5, the quality of BMF was best, and relaxation density of the BMF briquette was 0.98 g/cm3. When the moisture content stayed same, the forming pressure increased correspondingly with the increase of the LDR of the forming mould. When the LDR of the forming mould stayed the same, the moulding pressure increased first and then decreased with increase of moisture content. This study is of great significance because it demonstrates improvement in the utilization range of hickory husks, with the potential for reducing environmental pollution and increasing farmers’ income.

In the era of a digital economy, business model innovation takes on a critical significance to the transformation of conventional manufacturing enterprises. Factors for the innovation originate from both inside and outside the manufacturing enterprises. Previous studies focused on external factors, and few on the main factors of innovation. With Chinese wooden furniture manufacturing enterprises as an example, the paper focuses on the effect of innovation subject factors on the formation and practice of business model innovation planning. It was found that employees of all ages and levels have different ideas about business model innovation practice, and learning and absorptive abilities of employees, entrepreneurship, and factors at all dimensions of enterprise culture at the organizational level play an active promoting role at different stages of business model innovation, among which enterprise culture has a regulatory effect. This study enriches the research field about the effect of innovation subjects on business model innovation behaviors, and provides reference for wooden furniture manufacturing enterprises and even conventional manufacturing enterprises to facilitate the realization of business model innovation.
