METHOD FOR MAKING STATIC-DISSIPATIVE COMPOSITE STRUCTURE WITH EXPOSED CONDUCTIVE FIBER

Petro Guardian, L.L.C., ...

1. A method for making an object with an electrically conductive surface, comprising the steps of:1) applying a mask to a conductive fiber material, wherein the mask inhibits infiltration of a liquid resin into the conductive fiber material, and wherein the mask is not applied to some areas of the conductive fiber material;
2) disposing the conductive fiber material and the mask on a mold;
3) disposing a structural fiber and the liquid resin on the conductive fiber material and the mold, such that the liquid resin infiltrates the unmasked areas of the conductive fiber material;
4) curing the resin;
5) releasing the conductive fiber material, the structural fiber and the cured resin from the mold; and
6) removing the mask from the conductive fiber material, such that the conductive fiber material becomes exposed in the previously masked areas.
