Abstract: In this paper we studied the pultrusion method of notor wedges vrohirh is composed of polydiphenyl oxide derivatives or xylene formaldehyce unsaturated polyester resins as a matrix and the continuous glass rovings as a reinforcement. The efforts of various processing conditions on the properties of the products are studied and discussed. The optimum proecssing conditions are also proposed.It is proved by the epxerimental results that tte polydiphenyl oxide derivatives and xylene formaldehyde unsaturated polyester resins are suitable for using in the motors of Class B and motors of Class B, F, H,respectively.
