Abstract

In this study, the dynamic axial crushing behaviour of tubular specimens with varying geometric shape and dimensions made of glass fibre reinforced polyamide 6 composites containing either a fibre mat or a continuous bidirectional fibre reinforcement is experimentally analysed. In addition, the influence of hybridisation on the crushing behaviour is investigated using two different layer-by-layer configurations in order to increase the crushing performance compared to the source composites. All four composite configurations exhibited comparable damage and failure mechanisms, which are crucial for energy absorption. It is shown that hybrid composite specimens show more stable and efficient crushing behaviour, demonstrating up to a 26% increase in specific energy absorption and up to 33% enhancement in crush efficiency compared to both non-hybrid source materials. In particular, the hybrid configuration with a single layer of continuous bidirectional fibre reinforcement exhibits a significant improvement. The results demonstrate that hybridisation improves energy absorption and dynamic crushing performance, providing a basis for the potential use of recycled and recovered fibres in fibre mat-reinforced composites.

改进动态破碎性能的混杂玻璃纤维增强复合材料结构设计

在这项研究中，实验分析了由含有纤维垫或连续双向纤维增强的玻璃纤维增强聚酰胺6复合材料制成的具有不同几何形状和尺寸的管状试样的动态轴向破碎行为。此外，为了提高破碎性能，采用两种不同的分层配置，研究了杂化对破碎行为的影响。所有四种复合材料结构都表现出类似的损伤和破坏机制，这对能量吸收至关重要。结果表明，与非混合材料相比，混合复合材料样品显示出更稳定和有效的破碎行为，比能量吸收增加了26%，破碎效率提高了33%。特别是，具有单层连续双向纤维增强的混合结构表现出显着的改善。结果表明，混化改善了能量吸收和动态破碎性能，为再生和回收纤维在纤维垫增强复合材料中的潜在应用提供了基础。

期刊介绍： The past few decades have seen outstanding advances in the use of composite materials in structural applications. There can be little doubt that, within engineering circles, composites have revolutionised traditional design concepts and made possible an unparalleled range of new and exciting possibilities as viable materials for construction. Composite Structures, an International Journal, disseminates knowledge between users, manufacturers, designers and researchers involved in structures or structural components manufactured using composite materials. The journal publishes papers which contribute to knowledge in the use of composite materials in engineering structures. Papers deal with design, research and development studies, experimental investigations, theoretical analysis and fabrication techniques relevant to the application of composites in load-bearing components for assemblies, ranging from individual components such as plates and shells to complete composite structures.
