Method for making a molded composite article

摘要

A method for making a molded composite article includes the steps of: providing a sleeve body on a pressing portion of a male mold body, the sleeve body being made of a heat-expansible material and having a primary engaging segment and an abutting segment; disposing a composite laminate material on a female mold body; moving the male mold body provided with the sleeve body toward the female mold body while the male mold body and the female mold body are heated; continuing to move the male mold body so that the pressing portion extends into the abutting segment and presses the composite laminate material to form the molded composite article; and separating the male mold body from the female mold body and removing the molded composite article.

1. A method for making a molded composite article, comprising the steps of:
a) providing a sleeve body on a pressing portion of a male mold body, the sleeve body being made of a heat-expansible material and having a primary engaging segment sleeved around the pressing portion and an abutting segment extending co-axially from the primary engaging segment and away from a pressing end surface of the pressing portion; b) disposing a composite laminate material on a female mold body to span an open side of a molding space of the female mold body, the female mold body having a bottom wall and a side wall that cooperate to define the molding space; c) moving the male mold body provided with the sleeve body toward the female mold body while the male mold body and the female mold body are heated so as to force the composite laminate material into the molding space and so as to cause the sleeve body to expand so that the abutting segment forces the composite laminate material to abut against the female mold body at a corner of the bottom wall and the side wall; d) continuing to move the male mold body so that the pressing portion extends into the abutting segment and that the pressing end surface presses the composite laminate material directly against the bottom wall of the female mold body to form the composite laminate material into the molded composite article; and e) separating the male mold body from the female mold body and removing the molded composite article from the molding space of the female mold body.
