Abstract

Abstract In this paper the mechanical characteristics of an innovative bioplastic material, the HBP® -HempBioPlastic® filament, is investigated. HBP® was recently patented by an Italian company Kanésis that focused its activity on nature-derived materials. The filaments are the upshot of an original process allowing to reuse the surplus of the agricultural supply chains and transform it into new sustainable materials. At first, the 3D printed HBP® samples were tested in tensile tests according to the ASTMD638 standard and monitored in term of deformations by the Digital Image Correlation techniques (DIC) in order to evaluate the stress-strain behavior of different HBP® textures under loading. In addition, using the HBP® and the results coming from the experimental campaign, the design of an exhibition pavilion was proposed. The pavilion was modelled starting from the geometric construction of the fullerene. The supporting modular structure is combined by HBP® modular elements, that can be produced by 3D printing or moulding. Finally, in order to demonstrate the feasibility of the proposed pavilion, a linear finite element analysis is presented on the base of the experimentally determined mechanical properties of HBP® elements, under the effects of wind and seismic environmental actions.

采用生态可持续材料增材制造的模块化展览结构设计

摘要本文研究了一种新型生物塑料材料HBP®-HempBioPlastic®长丝的力学特性。HBP®最近获得了一家意大利公司的专利，该公司专注于自然衍生材料。细丝是一个原始过程的结果，允许重新利用农业供应链的剩余，并将其转化为新的可持续材料。首先，根据ASTMD638标准对3D打印的HBP®样品进行拉伸测试，并通过数字图像相关技术(DIC)对变形进行监测，以评估不同HBP®纹理在加载下的应力-应变行为。此外，利用HBP®和实验活动的结果，提出了一个展览馆的设计。展馆的模型是从富勒烯的几何结构开始的。支撑模块化结构由HBP®模块化元素组合而成，可以通过3D打印或模塑生产。最后，为了证明所提议的展馆的可行性，在实验确定的HBP®元素的力学性能的基础上，在风和地震环境作用的影响下，提出了线性有限元分析。

期刊介绍： The aim of Curved and Layered Structures is to become a premier source of knowledge and a worldwide-recognized platform of research and knowledge exchange for scientists of different disciplinary origins and backgrounds (e.g., civil, mechanical, marine, aerospace engineers and architects). The journal publishes research papers from a broad range of topics and approaches including structural mechanics, computational mechanics, engineering structures, architectural design, wind engineering, aerospace engineering, naval engineering, structural stability, structural dynamics, structural stability/reliability, experimental modeling and smart structures. Therefore, the Journal accepts both theoretical and applied contributions in all subfields of structural mechanics as long as they contribute in a broad sense to the core theme.
