High speed infrared imaging is being implemented to assess the thermal profile and energy transfer from an impactor onto a solid woven carbon fiber re-enforced plastic. Solid laminate composite specimens were impacted with both blunt and sharp tools while either the front or back surface is monitored with a high frame rate infrared camera. The post impact damage was evaluated and characterized using digital radiography and computed tomography techniques. Matrix cracking and delaminated plies are the two primary failure mechanisms. This presentation explores the energy balance equations within the elastic-plastic regime and describes the challenges of collecting viable temperature measurements for composites under transient loading. Measured temperature increases reveal there is a correlation to relative loss of the composite's transverse stiffness that is directly related to the energy absorbed by the plies. Composite layup configuration and last ply orientation with its influence on failure will also be discussed.
