The Effects of Photoinitiator Addition to the Mechanical and Physical Properties of the Epoxy and Vinyl Ester Fiber Glass Laminated Composites
Ultra-violet (UV) curing process is introduced in the curing of polymer matrix composites (PMC) for the application in producing bullet proof vest. Two types of matrix materials were used: epoxy and vinyl ester. Each of them were mixed with different types of photoinitiator; Bisacyl Phosphine Oxide...
