Non-woven Fabric Reinforced Cellular Textile Composites with Improved Energy Absorption Capacity

摘要

Flat-topped grid-dome cellular composites made of non-woven PET fabric reinforcement with polypropylene (PP) matrix were subjected to quasi-static axial compression and impact conditions. The mechanism of deformation and the energy absorption characteristics of the cells were studied. Based on the observations of the cell deformation mode, analytical expressions were formulated to find the mean peak value and thus the energy absorption capacity of the cellular structure. The results obtained are in good agreement with the experimental results.
