Abstract
The objective of this proposal is to demonstrate innovative methods for improving the interlaminar shear strength of 2-D fiber reinforced ceramic matrix composites. This would yield cost-effective, load bearing, structural components for turbine engine applications. Continuous and chopped ceramic fibers, respectively, will be used to provide fiber reinforcement in the through-thickness directin to inhibit shear between plies. A 2-D Nicalon TM fiber reinforced alumina matrix composite fabricated via the directed metal oxidation process will be used in this study. The effectiveness of the technical approaches used will be evaluated by interlaminar shear tests using the short beam method and the double notch shear test. Composite tensile and flexural strenght, toughness, coefficient of thermal expansion, and thermal conductivity will also be measured. Lanxide Corporation is well staffed and equipped to carry out the proposed research effort. Lanxide's extensive experience in composite development and characterization provide excellent prospects for success in the proposed program.
