Abstract
PURPOSE: To obtain a perforated FRP product without causing deterioration of strength by a method wherein before the resin is hardened, a preliminary hole is made by breaking the fibers nearly in the center of a portion to be perforated and then a pointed pin is pierced and removed after the resin is heated and molded.
CONSTITUTION: Approximately at the center of the portion 12' to perforate a final finished hole on an unhardened molded product 11' manufactured in a desired shape is provided a preliminary hole 12A smaller than said finished hole of the final product and a pointed pin 14 having a section of the same shape as the desired hole 12' is pierced through. Mold-releasing agent preferably is coated previously on the pin. When the resin is heated as the pin is inserted and then hardened and the pin is removed, the desired hole 12 is obtained on the finished product 11.
