Abstract

The present study investigates the effects of close-range blast loading of fibre metal laminates (FMLs) fabricated from woven glass polypropylene and aluminium alloy 2024-T3. The polypropylene layers and anodized aluminium are stacked in 3/2 layering configuration to investigate the impact energy absorbed through deformation and damage. In order to study the blast responses of FMLs, a 4-cable instrumented pendulum blast set-up is used. Effects of blast impulse and stand-off distance were examined. Investigation of the cross-section of FMLs are presented and damages such as fibre fracture, debonding, and global deformation are examined. Increasing stand-off distance from 4 to 14 mm resulted in a change of damage mode from highly localized perforation to global deformation.

摘要

本研究调查了由编织玻璃聚丙烯和铝合金2024-T3制成的纤维金属层合板（FML）的近距离爆炸载荷效应。聚丙烯层和阳极氧化铝以3/2层配置堆叠，以研究通过变形和损伤吸收的冲击能量。为了研究FML的爆炸响应，使用了一种4电缆仪器化摆式爆炸装置。研究了爆炸脉冲和间距的影响。展示了FML的横截面调查结果，并检查了诸如纤维断裂、脱粘和整体变形等损伤情况。将间距从4毫米增加到14毫米导致损伤模式从高度局部穿孔转变为整体变形。
