HIGH TEMPERATURE INORGANIC STRUCTURAL COMPOSITE MATERIALS
Abstract
Two phosphate bonded matrix materials for a composite system were studied. Polymorphism of the aluminum phosphate was responsible for wide variance in physical properties of the matrix material. Composites formed of these matrix materials reinforced with E-glass fibers had strengths two and one- half times that of matrix alone. Studies were conducted of the effect of corrosion on the fibers by the phosphate material. Corrosion varied as method of processing with wet layup specimens being more corrosive and dry pressed specimens being least corrosive. Boron fibers were investigated as a possible reinforcement material. Boron fibers were more corrosive resistant than glass fibers, but also were more brittle, presenting a processing problem. Microscopic examination of the fibers revealed several interesting structural habits of these fibers. Strength properties of the composites were determined on an automatic stress-strain apparatus designed and built specifically for that purpose.
