Assessment of Effectiveness of Date Palm Fibers in Foam Filled CFRP Energy Absorption Devices

摘要

The effectiveness of date palm fibers as a second order filler was assessed in octagonal/hexagonal hybrid energy absorption devices.. The cells inside the device were made from carbon fiber-reinforced plastics CFRP whereas; the outer skin was of Aramid/epoxy. The energy absorption devices were filled by date palm fibers and then the liquid foam was applied. The idea is to use the fibers to absorb the energy in various damage mechanisms and use the foam as a binder. The comparison showed higher peak load and average crushing load (for some cases) for the specimens filled with date palm and foam together. On the other hand, the specimens filled with foam only showed higher stroke efficiency and lower weight which led to a higher specific energy absorption.
