摘要

This paper presents experimental results for the processing and mechanical properties of carbon fiber reinforced composites with newly developed amorphous, asymmetric, and addition type polyimides (Triple A-PI). The imide oligomers were synthesized from the reaction of 2,3,3',4'-biphenyltetracarboxylic dianhydride (a-BPDA), 4,4'-oxydiaminine (ODA), and phenylethynyl phthalic anhydride (PEPA). Even though the molecular weight of the imide oligomer is relatively low, the cured polymer exhibits excellent mechanical properties because of its irregular and asymmetric structure. Unidirectional carbon fiber reinforced composites were fabricated by prepreg consolidation. The composites exhibit high glass transition temperature, and excellent shot beam shear strengths at elevated temperature compared to PETI-5.
