Abstract: A hybrid reinforcing fabric includes glass fibers and carbon fibers. The hybrid reinforcing fabric can be readily infused at an acceptable infusion speed, without requiring that the carbon fiber tows used resin. Thus, the fabric provides for an effective one-step (i.e., in the mold) infusion process during composite part formation.

Abstract: Fabrics formed from a multitude of continuous fibers, each of the fibers including many individual filaments, are disclosed. The fibers are held together by a stitching yarn. Properties of the stitching yarn allow a resin to more readily flow through the fabric.

Abstract: A fiber-reinforced fabric, composite materials formed from such fabrics, and methods of making the fiber-reinforced fabric or composite materials, are provided. The fabrics and composite materials demonstrate improved fatigue performance relative to conventional fiber-reinforced fabrics.

Abstract: A hybrid reinforcing fabric includes glass fibers and carbon fibers. The hybrid reinforcing fabric can be readily infused at an acceptable infusion speed, without requiring that the carbon fiber tows used to form the hybrid reinforcement fabric be spread or pre-impregnated with resin. Thus, the fabric provides for an effective one-step (i.e., in the mold) infusion process during composite part formation.

Abstract: This electrolyte material for an electrically controllable device having variable optical/energy properties is in the form of a self-supported layer intended to be placed between two layers of electroactive material, and comprises or consists of a matrix which is capable of maintaining the mechanical strength thereof and in which are inserted ionic charges capable of allowing, under the action of a current, oxidation and reduction reactions in adjacent layers of electroactive material. The ionic charges are within the matrix in the solubilized state, solubilized by a solubilization liquid (L). The matrix is chosen to provide the percolation pathway for the ionic charges.
