Knee braces enlist epoxy composite
Modeling and tooling systems, and epoxy resin from Ciba-Geigy Corp. helped Innovation Sports of Irvine, Calif., create ``The Edge'' knee brace.
Made of metal and a carbon fiber/fiberglass/epoxy laminate, the knee brace is designed to provide sports enthusiasts and joggers with the performance of custom-made braces at an off-the-shelf price, according to Ciba-Geigy.
Ciba-Geigy's Formulated Ma-terials Group of East Lansing, Mich., supplied modeling and tooling systems, including its Ren Shape 450 modeling material, Ren RP 1129 surface coat, Ren RP 1700-1 epoxy for the tooling intermediate and laminating braces and Ren RP 3209-1 iron oxide-filled black epoxy for the mold.
Innovation Sports wets down graphite ply with RP 1700 epoxy after fiberglass layers are applied to the mold.
The laminate is cured at 150 F for about 40 minutes and at room temperature for another 72 hours.
The braces are then sanded and coated with an ultraviolet cure system.
