摘要
Two aromatic polyimides and an aromatic polyamide-imide were tested in single-edge-notched tension. Fracture toughnesses, Kc, normalized to 25 μm film thickness ranged from 1.65 to 5.4 MPa m12. LARC-TPI, a thermoplastic polyimide, showed evidence of crazing ahead of a growing crack whereas the other materials formed a shear yielded zone.
