Abstract

Ryton®-PPS carbon fiber reinforced composites have excellent temperature stability, chemical resistance, and toughness. As a result, the use of polyphenylene sulfide (PPS) carbon fiber composites is being evaluated throughout the aerospace and related industries. Critical molding parameters such as temperature, pressure, and cooling rate have been investigated both as a fundamental study concerning the polymer matrix and to provide assistance to molders. Initial results indicate that mechanical properties are influenced by the crystallinity of the molded composites. The property variations correlate with the crystallinity data obtained from differential scanning calorimetry (DSC) on the polymer matrix and composites.
