Design and Analysis of Bamboo Substrate Aramid Layered Composite Helmet Shell

Authors(1) :-Vivek V G

This work presents results from both experimental and numerical simulations of static deflection analysis of a Bamboo Substrate Aramid Layered Composite Helmet Shell and Impact absorption simulation test of the helmet shell to meet the world standards of a Helmet. The experiments involve applying design load at different points of the helmet while clamping at different positions. The material properties of Aramid layer and Bamboo substrate aramid layer is found out by performing three point bending tests on specimens cut from the helmet realized. The validation of material properties is done by comparing the experimental data with finite element model constructed from CT images and studied. A comparison of helmet deflection between the test and analysis using both tetrahedral and layered shell elements are made. Drop test simulation performed on the helmet shell with varying thickness of aramid layers to optimize thickness to satisfy the helmet standards .Using layered shell element explicit dynamic analysis is carried out for a touchdown velocity of 30km/hr. at a height of 2.2m from the ground as per the standard. A parametric study with progressively increasing aramid thickness (for a constant 2mm bamboo shell thickness) for the helmet under impact is studied.
