- Abstract
The results of an experimental investigation on the behavior of milled and short-fiber, reinforced composite plates are presented in this paper. The target operating temperature for, the plates was 1300°C. The principal variables were the type and volume fraction of fibers, and the matrix composition. Three fiber types and five fiber contents ranging from 2.5 to 10, weight percent were evaluated. The density of the samples varied from 1500 to 2800 kg/m3., For the matrix, the ratio between alumina and silica was varied from 1:1 to 5:1. The flexural, tensile strength, (modulus of rupture) varied from 10 to 95 MPa. The modulus of elasticity, varied from 5 to 60 GPa. There is a strong correlation between the unit weight and the, mechanical properties of strength and modulus. Load-deflection response in flexure, strength, and stiffness for the various mix formulations and their relation to unit weight are presented.
