US Patent 4,001,478 (granted Jan. 4, 1977) to Robert W. King, assigned to Avco Corporation, describes three-dimensional woven filamentary materials and the looms used to make them. Filaments on a Z axis are woven with X-axis and Y-axis filaments, compressed so inter-yarn friction holds the structure together, then impregnated with resin or another matrix and cured into a machinable composite billet. The patent describes a rectangular needle loom and a cylindrical weaving apparatus built from wound slats on a mandrel. It includes the claims, the description, and four sheets of drawings (Figs. 1-8). The scan contains both a USPTO web printout and the original patent print.
