Impact Compressive Character of Balanced Angle-Ply Carbon/Epoxy Composites

Abstract:

This paper discusses the response of balanced angle-ply graphite/epoxy composite laminates subjected to different strain rate compression loading using a compression split Hopkinson’s pressure bar (SHPB) and an MTS machine. Five types of laminates, with ply angles 0°, ±15°, ±45°, ±75°and 90°were manufactured using T700 carbon fiber with epoxy resin system by hand. Samples were subjected to compression loading at different strain rates along longitudinal direction. The stress-strain curves at different strain rates were compared for each sample type. Characteristics of the curves were summarized and the causes were analyzed. Finally, the relationship between failure strength and ply angles was analyzed.
