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.
Claims12
A fabric for reinforcing a composite material formed in combination with a resin, the fabric comprising first fibers and second fibers;
- wherein the first fibers are oriented parallel to one another;
- wherein the second fibers are oriented parallel to one another;
- wherein the second fibers are oriented perpendicular to the first fibers;
- and
- wherein a ratio of first fibers to the second fibers is 15:1 to 25:1;
- wherein the fabric is characterized by the first fibers including a first sizing and the second fibers including a second sizing, the first sizing being compatible with the resin and the second sizing being incompatible with the resin.

A method of making a composite material, the composite material formed from a fabric and a resin, wherein the fabric comprises first fibers and second fibers;
- the method comprising:
- applying a first sizing to the first fibers;
- applying a second sizing to the second fibers;
- positioning the first fibers in a parallel first arrangement, positioning the second fibers in a parallel second arrangement, wherein the first arrangement is perpendicular to the second arrangement, and wherein the ratio of first fibers to second fibers is 15:1 to 25:1;
- infusing the fabric with the resin;
- curing the resin to form the composite material;
- wherein the first sizing is compatible with the resin and the second sizing is incompatible with the resin.
