✦ 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.
