A jacquard type loom for making a fabric by weaving plural warp yarns with plural weft yarns, the fabric including a determined number of columns of warp yarns per unit length and a determined number of layers of weft yarns. The loom includes a comber board including plural holes passing a corresponding number of control cords, each control cord including an heddle eye through which a warp yarn passes. The holes are distributed in a determined number of columns extending parallel to the warp yarn direction and a determined number of rows per column extending in a direction perpendicular to the warp yarn direction. The comber board includes a number of columns of holes per unit length smaller than the number of warp columns in the same unit length in the fabric, and a number of rows of holes greater than the number of warp layers in the fabric.

A three-dimensional corner lap joint preform and a method of forming a three-dimensional corner lap joint preform including a woven flange with one or more legs that extend from the flange. The legs may include one or more independently woven portions which allow formation of a corner without darting the leg or adding additional reinforcement. The independently woven portions may include warp fibers which are not woven into the preform. The unwoven area allows removal of a portion of the leg prior to formation of the corner, allowing the portions of the leg to overlap and form a lap joint.

A woven preform for a reinforced composite material, which may be woven flat and folded into shape. The preform has off-axis reinforcement with one or more legs and/or base extending in an off axis or bias (non 0/90 degree) orientation with respect to the warp/weft fibers. One or more legs extend from a base, the base and legs each having at least two layers of warp fibers. The legs may be parallel or angled to each other. The outer ends of the base and/or the legs may have tapers formed from terminating layers of warp fibers in a stepped or angled pattern.

Preforms including fiber reinforced nodes for use in fiber reinforced composite structures and methods for making fiber reinforced composite structures. Preforms with woven fabric elements extending radially from a common node include at least one reinforcing fiber interwoven between at least two elements and passing through the node. A method of assembling preform structures using the preforms to provide a structure with reinforced nodes.
