Abstract

Ballistic perfonnance of all-glass, all-aramid and aramid-glass fibre-reinforced phenolic resincomposite laminates has been evaluated against 0.30 in. calibre soft ball and hard armour piercing (AP) bullets. It is observed that mass effective ness of glass fibre phenolic composites against impacts by APbullets can be improved by aramid fibre'reinforcement in the back of laminate. The perfonnance of a ramid phenolic composites against ball ammunition can be improved by hybridisation with glass fibre reinforcement at the front.
