The invention relates to a process for making swaged lighting holes () in planar areas of parts () made of preimpregnated composite, by means of which the part () is arranged between a female tooling () with the final shape of the bottom side of the swaged part and a caul plate () with the final shape of the top side of the swaged part, except in an area () which must be swaged, pressure Pis applied on the caul plate () in the area of the part () that must be maintained substantially planar, and pressure Pis applied by means of a male tooling () on the area () of the part () which must be swaged at a forward speed allowing the flow of the resin during the slippage of the fibers of the material so that it may deform, adapting to the final shape of the female tooling ().

Process for making swaged lighting holes in planar areas of preimpregnated composite parts

The present invention relates to a process for manufacturing composite ring frames for aeronautical fuselages by means of the application of the RTM technology to two preforms with C- and L-shaped sections manufactured using two tools () in the following steps: providing the material; hot-forming planar rectangular laminates (); hot-forming laminates of right angle section () on one part of right angle section of the first tool (), placing an elastic membrane () and applying a temperature and vacuum cycle; hot-forming the preforms into a C shape () and L shape () on a second curved tool () by deforming said laminates of right angle section () thereon, and applying a temperature and vacuum cycle. The invention also relates to said tools ().
