Abstract

Disclosed are compositions of short fiber reinforced phenolic foams, methods of making and using the same. The disclosed fiber-reinforced phenolic foams have a seven-fold increase in peel resistance over the unreinforced counterpart foam. The phenolic foam has enhanced fracture toughness without sacrificing the critical fire retardant properties.
