Improving the ballistic performance of ultra high molecular weight polyethylene fiber reinforced composites using conch particles

A new method was proposed to improve ballistic impact performance of unidirectional ultra high molecular weight polyethylene (UHMWPE) fiber plate (UD plate) by adding shell particles in matrix. The complex micro-laminate structure of these bio-composite materials was studied. It was revealed by Scanning Electron Microscopy (SEM) and Fourier Transform Infrared Spectroscopy (FT-IR) spectra that modified shell particles were uniformly dispersed in the matrix. The results of ballistic tests and temperature adaptation tests demonstrated that the bulletproof property of the modified UD plate was improved by 20%.
