A novel semicrystalline polyetherketoneketone (PEKK) polymer is being developed as a potential high-performance thermoplastic matrix system for advanced composites. This resin with upper use temperature between those of Du Pont's K-3 (polyimide) and J-2 (polyamide) has potential advantages versus other commercial organic matrix systems. The carbon-fiber reinforced composite laminates with PEKK matrix prepared from the proprietary melt impregnated tows showed high flexural, shear, and compressive strengths, excellent environmental durability and hot-wet stability. PEKK neat resin and its carbon composite properties are presented and discussed. 4 references, 4 figures, 4 tables.
