Thermoelastic properties of unidirectional filamentary composites by a semiempirical micromechanics theory. [B, C, and glass-filament epoxy-resin composites]
A unified, semiempirical micromechanics theory is described which relates the thermoelastic properties of the unidirectional, filamentary composite to the quantities and to the corresponding properties of its constituent materials. The theory treats the composite, the filaments and the matrix as being generally orthotropic, linearly elastic, and accounts for the effect of voids. It is based on the equivalent section concept, on parallel- and series connected elements and on the judicious incorporation of certain empirical factors, which reflect the particular fabrication process. Results are presented which demonstrate and verify application of this theory to boron, carbon and glass-filament epoxy-resin composites. Additional results are presented which exhibit the voids and in-situ matrix orthotropicity effects on the thermoelastic properties of the unidirectional composite. Finally, results are included for all the thermoelastic properties of boron, carbon and glass-filament epoxy-resin composites.
