Notes:
The possibility of using fibers of varying thermal expansivities to reduce stresses generated from thermal gradients in service was explored. Laminates of aluminosilicate- and alumina-matrix composites were fabricated using a combination of Nextel 610™ and Nextel 720™ fibers. The composites were tested for mechanical behavior and thermomechanical behavior in comparison to control composite specimens which contained a single type of fiber. Mixed-fiber composites show strength and fracture behavior similar to those of single-fiber-type composites. Their thermomechanical behavior is consistent with 2D laminate models, making it possible to design composites using such models. Interlaminar shear stress is a key, but sole limitation and the use of gradation in fiber mixture is suggested.
