1. An aircraft seat spreader beam corresponding to outer sides of a seat pan and seat back of an assembled aircraft seat, the aircraft seat spreader beam comprising:
(a) a central part formed of a fibrous material suspended in a thermoplastic matrix, the central part having a continuous periphery forming a predetermined shape and internal portions separated by an array of weight-reducing interior voids, the internal portions are each diagonally oriented relative to the continuous periphery and directly connected to the continuous periphery thereby reinforcing the central part;
(b) a first and second side part, each side part formed of woven materials embedded in a thermoplastic matrix; and
(c) the central part positioned between the first and second side parts being directly bonded together while in a heated thermoplastic state to form a single, integral structure with the absence of discontinuity across the bond plane of the structure, wherein:
the spreader beam includes a through hole adapted for attachment of the aircraft seat spreader beam to an aircraft seat.
