Abstract Application of flax fibre as reinforcement in polymer composites used in the construction and manufacturing industries is a step towards achieving more sustainable construction practices. Flax fabric-reinforced epoxy (FFRE) was used to manufacture forty-two pipes with a variety of internal diameters and flax fabric layers, all with a length-to-internal diameter ratio of 1.5:1. Lateral compression loading was performed on the FFRE pipes to establish the effect of internal diameter and number of fabric layers on the strength, energy absorption capability, strains, and failure mechanism. When compared to previously reported test results for pipes manufactured from different natural fibre composites, the FFRE pipes manufactured in this study and subjected to lateral compression showed higher strength, flexibility, and specific energy absorbed while demonstrating comparable strength, specific strength, and specific energy absorbed with synthetic and hybrid fibre composite pipes.

亚麻织物增强环氧树脂管经受横向压缩

摘要 亚麻纤维在建筑和制造行业使用的聚合物复合材料中作为增强材料的应用是朝着实现更可持续的建筑实践迈出的一步。亚麻织物增强环氧树脂 (FFRE) 用于制造 42 根不同内径和亚麻织物层的管道，所有管道的长度与内径之比均为 1.5:1。对 FFRE 管进行横向压缩载荷，以确定内径和织物层数对强度、能量吸收能力、应变和失效机制的影响。与之前报道的由不同天然纤维复合材料制成的管道的测试结果相比，本研究中制造的 FFRE 管道经受侧向压缩显示出更高的强度、柔韧性、
