Title: Mechanical properties of hybrid (medium modulus graphite, Thornel P-55 Kevlar/Epoxy) composites

This paper treats the mechanical behavior of hybrid (Thornel P-55-Kevlar/Epoxy) composites under ambient conditions and under hostile environments. Interply (core/shell) and intraply tubes (5.75'' I.D.) were filament wound and NOL rings were machined from them. Apparently modulus and apparent strength were measured using the split D (ASTM D2290) test. The influence of boiling water exposure (2 hrs and 24 hrs) on short beam shear strength, apparent modulus, and apparent strength was also evaluated at room temperature and the fracture toughness for above configurations was measured at room temperature. Scanning electron microscopy was used to examine failure modes. 6 references, 4 figures, 3 tables.
