Method of fabricating fiber-reinforced articles

Abstract: FILMENTS CHARACTERIZED BY HIGH STRENGTH, HIGH RIGIDITY, AND HIGH RESISTANCE TO DETERIORATION AT ELEVATED TEMPERATURES ARE UTILIZED IN A PROCESS OF FABRICATING A MULTILAYER FIBER-REINFORCED METAL MATRIX COMPOSITE BY WINDING A FILAMENT ON A FOIL-COVERED, SPRING-LOADED MANDREL, PREHEATING THE MANDREL, PLASMA ARC SPRAYING METAL MATRIX MATERIAL IN COALESCENT FORM ONTO THE FILAMENT WINDINGS SO AS TO FORM A MONOLAYER TAPE, AND DIFFUSION BONDING A PLURALITY OF SUCH TAPES TOGETHER IN LAYERS, THE PROCESS BEING CHARACTERIZED BY A HIGH DEGREE OF REPRODUCIBILITY.

Fabrication of Metal Matrix Composite Materials

Abstract: The analysis of the limiting factors associated with ultimate strength of metal matrix composite materials provides a basis for applying boundary conditions to potential fabrication techniques. The boundary conditions are formulated through an understanding of fiber degradation, fiber-matrix interface and reactivity and processing effects (residual stress). The boron-aluminum system is considered for definition of boundary conditions. These condi tions are compared with test data generated from composites fabri cated by both liquid and solid state techniques. Considerations for future research in the area of metal matrix composite fabrication techniques are proposed.
