Abstract
A method of manufacturing includes producing a powder resin comprising a polymer precursor and a thermal initiator, packing a fiber structure with the powder resin, resulting in a resin-packed structure, and heating the resin-packed structure to a curing temperature high enough to melt and cure the resin-packed structure to form a final structure.
