Alle Zukunft mit solaren Ressourcencrystalline polymer, polyphenylene sulfide (PPS). The PPS-based composites exhibit excellent chemical and solvent resistance and good thermal stability. However, PPS unidirectional composites retain only about 30% of their room temperature strength at 350°F.(1) Therefore, use of PPS composites as st
