Abstract

Climate change is one of the main factors influencing the research of environmentally friendly materials. This is why the use of engineering fibers as a reinforcement technique in wood, in order to increase its mechanical properties, has recently been investigated. This research presents the results obtained from the use of carbon and basalt fiber fabrics as a reinforcement for microlaminated Radiata Pine wood panels at a laboratory scale using the adhesives epoxy resin and polyvinyl acetate. Tests were carried out in comparison to the control boards, relating the physical properties obtained in terms of thickness swelling by 48 h-water immersion with a decrease of 19% for the polyvinyl acetate and carbon fiber matrix reinforcement, about the mechanical properties evaluated, a better performance was obtained for the epoxy resin and carbon fiber matrix reinforcement and in terms of flexural stiffness and strength (in flatwise), tensile strength and Janka hardness, with an increment of 31%, 38%, 56% and 41%, respectively.

碳和玄武岩纤维与胶粘剂的结合改善单板层压木材的物理机械性能
气候变化是影响环保材料研究的主要因素之一。这就是为什么最近研究了使用工程纤维作为木材的加固技术,以增加其机械性能。本研究展示了使用碳和玄武岩纤维织物在实验室规模上使用粘合剂环氧树脂和聚醋酸乙烯酯作为微层压辐射松木板的增强剂所获得的结果。与控制板进行了对比试验,对比了聚氯乙烯和碳纤维基体增强板在48 h水浸泡下厚度膨胀的物理性能,减少了19%;对比了机械性能,环氧树脂和碳纤维基体增强板在抗弯刚度和强度(平面)、抗拉强度和Janka硬度方面的性能更好。增幅分别为31%、38%、56%和41%。

期刊介绍: Applied Sciences (ISSN 2076-3417) provides an advanced forum on all aspects of applied natural sciences. It publishes reviews, research papers and communications. Our aim is to encourage scientists to publish their experimental and theoretical results in as much detail as possible. There is no restriction on the length of the papers. The full experimental details must be provided so that the results can be reproduced. Electronic files and software regarding the full details of the calculation or experimental procedure, if unable to be published in a normal way, can be deposited as supplementary electronic material.
