Abstract:

Analysis was directed toward obtaining a quantitative estimate of the residual stresses resulting from curing of a glass monofilament encased in a concentric cylinder of resin. As the composite is cured, in general, it develops residual tensile stresses which will add to those produced by the external loading to initiate cracks in the resin. These cracks will expose the surface of the fiber and provide sites for fracture initiation in the composite. The stresses at the interface of filament and resin were analyzed. The axial stress in the resin will be the decisive stress to initiate crack in the resin in a direction perpendicular to the axis of the composite. This will break the resin into lengths which will depend upon the shear strength of the resin. The optimum design of the composite is shown as a function of the resin content and glass content.
