Advanced composite materials or high performance polymer composites are an unusual class of materials that possess a combination of high strength and modulus and are substantially superior to structural metals and alloys on an equal weight basis The book provides an overview of the key components that are considered in the design of a composite of surface chemistry of analyses/testing of structure/property relationships with emphasis on compressive strength and damage tolerance Newly emerging tests particularly open hole compression tests are expected to provide greater assurance of composite performance This publication is an up to date treatment of leading edge areas of composite technology with literature reviewed until recently and includes thermoplastic prepregs/composites and major application areas
