Properties of two composite materials made of toughened epoxy resin and high-strain graphite fiber

Marvin B. Dow, Donald Lawrence Smith

Open full text 16 citations

Abstract

Results are presented from an experimental evaluation of IM7/8551-7 and IM6/18081, two new toughened epoxy resin, high strain graphite fiber composite materials. Data include ply-level strengths and moduli, notched tension and compression strengths and compression-after-impact assessments. The measured properties are compared with those of other graphite-epoxy materials.
