Characterization of Composites Response at High Rates of Loading

By: Nasa, National Aeronautics and Space Adm

The objective of the proposed research is to experimentally study the effect of strain rate on mechanical response (deformation and failure) carbon fiber/epoxy matrix composites. The experimental data provide the information needed for the development of a nonlinear, rate dependent deformation and strength models that can subsequently be used in design. This year effort was directed into testing the epoxy resin. Two types of epoxy were tested each in tension and shear at various strain rate that ranges from 5x10(exp -5), to 700/s. The results show that both the strain rate and the mode of loading affect the epoxy response.Gilat, AmosGlenn Research CenterEPOXY MATRIX COMPOSITES; EPOXY RESINS; TENSOR ANALYSIS; LOADS (FORCES); STRAIN RATE; FIBER COMPOSITES; TENSILE DEFORMATION; FAILURE
