Abstract

The low-velocity impact behaviour of pineapple leaf fiber, PALF reinforce epoxy composite (P), PALF hybrid (GPG), and four-layer woven glass fiber (GGGG) composite was investigated. As for post-impact analysis, the damage evaluation was assessed through photographic images and X-ray computed tomography, using CT scan techniques. The key findings from this study are that a positive hybrid effect of PALF as a reinforcement was seen where the GPG shows the delayed time taken for damage initiation and propagation through the whole sample compared to GGGG. This clearly shows that the addition of fibers does have comparable composite properties with a fully synthetic composite. Through the visual inspection captured by photographic image, the presence of woven fiber glass mat in GPG presents a different damage mode compared to P. Moreover, CT scan results show extended internal damage at the cross-section of all impacted composite.

摘要

研究了菠萝叶纤维（PALF）增强环氧复合材料（P）、PALF混杂复合材料（GPG）和四层编织玻璃纤维复合材料（GGGG）的低速冲击行为。至于冲击后分析，使用CT扫描技术通过摄影图像和X射线计算机断层扫描对损伤进行评估。本研究的主要发现是，PALF作为增强材料具有积极的混杂效应，与GGGG相比，GPG显示出损伤起始和在整个样品中传播所需的时间延迟。这清楚地表明，添加纤维确实具有与全合成复合材料相当的复合性能。通过摄影图像进行的目视检查发现，GPG中编织玻璃纤维毡的存在呈现出与P不同的损伤模式。此外，CT扫描结果显示，所有受冲击复合材料的横截面都存在扩展的内部损伤。
