Apparatus and methods for processing composite components using an elastomeric caul

摘要

Apparatus and methods for processing composite components using an elastomeric caul are disclosed. In one embodiment, a method includes forming a prepreg material on a non-planar portion of a lay-up mandrel, and providing an elastomeric caul over the prepreg material in an initial position such that a first portion of the elastomeric caul is proximate the prepreg material on the lay-up mandrel, and a second portion of the elastomeric caul adjacent the first portion is spaced apart from the prepreg material. Next, a pressure is reduced within a space disposed between the elastomeric caul and the lay-up mandrel proximate the non-planar portion. Simultaneously with the reducing of the pressure with the space, the elastomeric caul is stretched into a second position such that the second portion of the elastomeric caul is drawn proximate to at least one of the prepreg material and the lay-up mandrel.
