Abstract

To study the strength and mechanical properties of bi-composite of palm fibers sandwich matrix with ABS thermoplastic for ballistic armor. It is a product of polymer matrix composite which had attracts people because of its capability. This fiber and ABS thermoplastic mixed in the hot molding press. This process combines 2 principles which are pressure and temperature. The short fiber shows lower mechanical properties than the long fiber such as the impact strength. The short fiber is tested for 3 different fractions which are 10%, 15%, and 20%. The increasing of fiber reducing the elasticity and the composite become more brittle. The testing was done according to the standard ASTM. The impact strength of single layer is higher than the double cross and weave layer. However, it only can stand high force at single direction which is perpendicular to the fiber orientation. The microstructure of the composite can be seen through the Scanning Electron Microscope (SEM). From this microstructure, defects such as porosity, and inhomogeneous can be seen.
