Abstract: A method of manufacturing a flexible element configured for pressing against composite material received on a mold surface of a mold during cure, including placing a porous material over the mold surface, forming a sealed enclosure containing the mold surface and the porous material, infusing a curable liquid material such as silicone in liquid form into the enclosure under vacuum and through the porous material, curing the liquid material to form the flexible element, and opening the enclosure and disengaging the flexible element from the mold. In a particular embodiment, the flexible element is a pressure pad.

Abstract: A vacuum bag system (VBS) for forming pre-consolidated composite blanks hasa blank enclosure for sealing around a periphery of the blank, while leaving a second sideof the blank exposed, an articulated forming caul (AFC) with at least two facets, eachfacet effectively jointedly coupled to an adjacent facet, and having a respective,independently controlled, heater integrated with, or coupled to the facet. The VBS furtherhas a forming enclosure for sealing around a periphery of a tool. The blank enclosurebrings the blank and the facets into uniform thermal contact resistance and mechanicalcontact; and permits the articulated AFC to distribute thermal and mechanical load acrossthe blank during forming, even as the facets move to align to faces of the mold.

Abstract: A technique for automated online inspection of manufacture of a fibre reinforced polymer composite part during automated ribbon placement (e.g. ATL or AFP) uses interferometric inspection (e.g. OCT) to detect deviations from a planned lay-up for the part, to identify defects. On line, real-time inspection (i.e. on-the-fly) is demonstrated, and edge type defects and whole surface defects are identifiable. A sensor is demonstrated that does not extend a working envelope of the robotic head used for ribbon placement.

Abstract: A method of manufacturing a monolithic component having internal wall(s), including separately placing uncured composite material on a mold parts, placing the mold parts on a support plate with a portion of the uncured composite material extending between and in contact with the adjacent mold parts, interconnecting the adjacent mold parts through a connection allowing limited relative movement on the support plate along a direction corresponding to a thickness of the uncured composite material therebetween, biasing the adjacent mold part toward each other along the limited relative movement to provide a compressive force on the uncured composite material extending therebetween, and curing the composite material to obtain the monolithic component with each internal wall being formed between adjacent mold parts. The bias causes the adjacent mold parts to move toward each other as the thickness of uncured material extending therebetween reduces during curing. A tool assembly is also discussed.
