Abstract
The disclosure relates to polymer-containing composite materials and to unusually low-pressure consolidation methods for forming composite parts from such materials. More specifically, for example, the disclosure relates to use of a certain “PEEK-PEDEK” copolymer in low-pressure consolidation methods, using as little as 1 bar pressure (or using atmospheric pressure acting on a consolidation that is held under vacuum) to provide composite parts that are substantially void-free.
