Abstract
Impact resistance and weight are important features for ballistic materials. Kevlar fibers
are the most widely reinforcement for military and civil systems due to its excellent impact
resistance and high strength-to-weight ratio. Kevlar fibers or spectra fiber composites are
used for designing personal body armor to avoid human injury from aggressive action by
knife, sharp, spike, broken glass, and needle. So, wearer’s comfort also becomes a prerequisite of armor design to produce light-weight and comfortable armor.
In this study, the comfort properties of Kevlar/epoxy matrix are investigated. Two
innovative methods were used for the preparation of a Kevlar/epoxy composite by using
Kevlar fabric as reinforcement and epoxy resin as matrix in order to maintain the ballistic
impact performance of Kevlar-epoxy composite and to increase the comfort properties at
lower weight.
