The objective of this study was to characterize a composite unidirectional tape made with unsized Hercules IM7 fibers and a phenylethynyl terminated polyimide in the form of a polyamide acid. A processing study to examine the effect of cure parameters and robustness of the consolidation process was conducted and showed the versatile processing afforded by the phenylethynyl terminated polyimide. The mechanical and physical properties of laminates produced from the optimized composite cure process are presented and compared to a commercially available polyimide.
