Residual Strain and Strength Loss in Filament Wound Circular Rings. Final Report, October 13, 1980-September 30, 1981

摘要

Very high strength composite materials may be formed by the filament winding process using continuous filament yarns and a resin binder. The composite strength depends on the fibers being imbedded in the resin matrix in a straight path. This research aims at quantifying the relationships between fiber winding tension, mandrel stiffness, winding thickness, and composite strength. An analytical model is developed based upon the finite element method which models the winding process. Two types of cylinders were fabricated for experimental correlation with the analytical model.
