Yield and internal stresses in aluminum filled epoxy resin. A compression test and positron annihilation analysis
The influence of the filler content on the mechanical properties of an epoxy resin composite filled with aluminum powder was investigated. Compressive tests were performed at room temperature and at different strain rates. The response of the composites was also studied by positron annihilation life...
