に種々の試みがなされてきた。[Prior Art] Polyphenylene sulfide resin is known as a resin with excellent heat aging resistance, chemical resistance, and flame retardancy, but this resin alone has the major drawback of being extremely brittle. In some applications,
The strength was also insufficient. In order to solve this problem, a technique is generally used in which glass fiber is blended into polyphenylene sulfide resin, but although strength is certainly improved by blending glass fiber, the surface appearance is poor. This tendency becomes particularly pronounced when glass fiber is blended at a high concentration, and various attempts have been made to solve this problem.
