Impact Characterization of New Composite Materials.

Abstract

Dropped-weight instrumented impact tests were used in conjunction with ultrasonic C-scan inspection to characterize the impact response of several new graphite-fiber composite material systems. The AS4/Hercules 3501-6 graphite/epoxy was compared to the newer AS4/Hercules 2220-1, Celion High Strain/Narmco 5425 and IM6/Narmco 5445C systems in the 250 F (121 C) service category. Material tested in the XAS/Hysol 9102 and HX/Hexcel 1516 graphite/bismaleimides. A material ranking is given along with measured impact parameters and impact energy versus damage relationships. The impact behavior of all four 250 F (121 C) were similar except IM6/5245C had the highest impact resistance. The bismaleimides had similar incipient damage levels as the epoxies but were more easily punctured. Impact resistance of the five 350 F (177 C) systems were similar except T300/130B had the lowest impact resistance. Keywords: Impact tests; Instrumented impact; Graphite fiber; Epoxy composites; and Bismaleimide.
