Abstract

Bio- and green composites are mainly used in non-structural automotive elements like interior panels and vehicle underpanels. Currently, the use of biocomposites as a worthy alternative to glass fibre-reinforced plastics (GFRPs) in structural applications still needs to be fully evaluated. In the current study, the development of a suited biocomposites started with a thorough review of the available raw materials, including both reinforcement fibres and matrix materials. Based on its specific properties, hemp appeared to be a very suitable fibre. A similar analysis was conducted for the commercially available biobased matrix materials. Greenpoxy 55 (with a biocontent of 55%) and Super Sap 100 (with a biocontent of 37%) were selected and compared with a standard epoxy resin. Tensile and three-point bending tests were conducted to characterise the hemp-based biocomposite.

摘要

生物复合材料和绿色复合材料主要用于非结构性汽车部件，如内饰板和车辆底盘。目前，在结构应用中，生物复合材料作为玻璃纤维增强塑料（GFRP）的一种有价值的替代品，其使用仍需进行全面评估。在当前的研究中，开发合适的生物复合材料始于对可用原材料的全面审查，包括增强纤维和基体材料。基于其特定性能，大麻似乎是一种非常合适的纤维。对市售的生物基基体材料进行了类似的分析。选择了Greenpoxy 55（生物含量为55%）和Super Sap 100（生物含量为37%），并与标准环氧树脂进行了比较。进行了拉伸和三点弯曲试验以表征大麻基生物复合材料。
