High strain rate mechanical properties of Cycom 5920/1583

Abstract: Polymer matrix composites offer excellent properties such as high specific strength and stiffness which make them attractive for many naval, aerospace and automotive applications. Although they are candidate materials for many applications where high strain rate or ballistic impact loading is probable, little is known of the material responses to shock loading for most composite materials. Because mechanical properties vary significantly with strain rate, the use of static properties in the analysis and design of structures which undergo dynamic loadings can on one hand lead to a very conservative overweight design, or on the other hand can lead to designs which fail prematurely and unexpectedly. The use of dynamic material properties will ensure the design of composite structures which are weight efficient and structurally sound when they are subjected to dynamic loads.
