What is claimed is: 1. A product comprising: an anti-intrusion beam for a vehicle door assembly, the anti-intrusion beam comprising a composite material comprising a fiber reinforcement, the fiber reinforcement having a plurality of fibers oriented at an angle between about 35 and 55 degrees with respect to a lengthwise dimension of the anti-intrusion beam. 2. A product as set forth in claim 1 wherein the angle is about 45 degrees. 3. A product as set forth in claim 1 wherein the fibers comprise glass. 4. A product as set forth in claim 1 wherein the fibers comprise carbon. 5. A product as set forth in claim 1 wherein the composite material comprises 2 to 6 layers of fiber reinforcement, each layer having fibers oriented at an angle between about 35 and 55 degrees with respect to the lengthwise dimension of the anti-intrusion beam. 6. A product as set forth in claim 5 wherein the composite material comprises 3 layers of fiber reinforcement. 7. A product as set forth in claim 1 wherein the anti-intrusion beam has a corrugated cross-sectional profile with a pair of ridges on an inboard side of the anti-intrusion beam. 8. A product as set forth in claim 1 wherein the composite material comprises an epoxy resin, a polyester resin, a vinyl ester resin, or a polyurethane resin. 9. A product comprising: a vehicle door assembly including an anti-intrusion beam connected to the vehicle door assembly, the anti-intrusion beam comprising a composite material comprising a glass fiber reinforcement, the glass fiber reinforcement having a plurality of weft and warp glass fibers oriented at an angle of about 90 degrees with respect to each other and each oriented at an angle between about 35 and 55 degrees with respect to a lengthwise dimension of the anti-intrusion beam, the anti-intrusion beam having a generally corrugated cross-sectional profile. 10. A product as set forth in claim 9 wherein the angle with respect to the lengthwise dimension of the anti-intrusion beam is about 45 degrees. 11. A product as set forth in claim 9 wherein the composite material comprises 2 to 6 layers of glass fiber reinforcement, each layer having glass fibers oriented at an angle of about 90 degrees with respect to each other and each oriented at an angle between about 35 and 55 degrees with respect to the lengthwise dimension of the anti-intrusion beam. 12. A product as set forth in claim 11 wherein the composite material comprises 3 layers of glass fiber reinforcement. 13. A product as set forth in claim 9 wherein the composite material comprises at least one of an epoxy resin, a polyester resin, a vinyl ester resin, or a polyurethane resin. 14. A method of making a product, the method comprising: forming an anti-intrusion beam for a vehicle door assembly comprising providing a composite material with a fiber reinforcement having a plurality of fibers, orienting the fibers at an angle between about 35 and 55 degrees with respect to a lengthwise dimension of the anti-intrusion beam. 15. A method as set forth in claim 14 wherein orienting the fibers comprises orienting the fibers at an angle of about 45 degrees. 16. A method as set forth in claim 14 wherein the fibers comprise glass. 17. A method as set forth in claim 14 wherein the fibers comprise carbon. 18. A method as set forth in claim 14 wherein the composite material comprises 2 to 6 layers of fiber reinforcement, and orienting the fibers comprises orienting the fibers in each layer at an angle between about 35 and 55 degrees with respect to the lengthwise dimension of the anti-intrusion beam. 19. A method as set forth in claim 14 comprising forming a corrugated cross-sectional profile in the anti-intrusion beam.
