Summary

Hot airframe structures require complex shaped parts made of ceramic matrix composite. Materials must have the potential for low cost fabrication by established polymer matrix forming techniques such as prepregging, lay-up and RTM. A study was conducted to evaluate the compatibility and performance of monazite (LaPO4) interface coatings with two such commercially available matrix systems. Cross-ply laminates of polymer derived silicon oxycarbide (Blackglas™) and sol-gel derived aluminosilicate matrix (Composite Optics, Inc.) panels were fabricated by wet lay-up. Both matrix materials were combined with monazite-coated and uncoated Nextel 610 and 312 oxide Fibers. Mechanical properties, microstructural and fractographic analysis are reported. Comparison to a commercially available BN-interface based system is made.
