β¦ Synopsis
Dynamic mechanical measurements and short beam shear tests have been used to characterize an Epon 828/MPDA epoxy resin and its composites with types A and HM carbon fibers. T, of the unfilled resin is sensitive to both epoxy stoichiometry and curing schedule. Composite properties depend on fiber type, fiber surface treatment and composite thermal history. Results are explained by a morphological model which includes both adsorptive and covalent interactions.

The work-of-fracture (ywOF) of carbon-carbon composites was measured for composites with 3-D woven fiber preforms, carbon felts, and chopped fibers. Maximum values were observed for the 3-D preforms and minimum values for the carbon felts. The values are also compared with similar data for graphites
The effect of anodic oxidation on high-strength polyacrylonitrilebased carbon fibers has been studied in terms of fiber surface energetics and fracture toughness of the composites. According to contact angle measurements based on the wicking rate of a test liquid, anodic oxidation leads to an increa
