A method for making a conductive pre-impregnated composite sheet includes the steps of joining a nanomaterial composite sheet, a fiber-reinforcing sheet and a resin system to form a combined sheet, heating the combined sheet, compacting the combined sheet, and cooling the combined sheet to form conductive pre-impregnated composite sheet including the fiber-reinforcing sheet, and the nanomaterial composite sheet coupled to the fiber-reinforcing sheet, wherein the fiber-reinforcing sheet and the nanomaterial composite sheet are embedded in the resin system.

In an example, an apparatus for generating a three-dimensional object includes a build area platform, a build material distributor, a secondary material ejection device, a coalescing agent ejection device, and a controller. The controller may control the secondary material ejection device to eject a secondary material in a predefined pattern over the build area platform, control the build material distributor to distribute a layer of the build material around the ejected secondary material, control the coalescing agent ejection device to eject the coalescing agent onto the layer of the build material, and control an energy source to apply energy onto the ejected coalescing agent to cause the build material in contact with the ejected coalescing agent to coalesce and solidify.

A method of manufacturing a wind turbine blade with integrated lightning strike protection is provided. The method includes forming a plurality of fiber reinforced plies having carbonized textile-grade PAN fibers. The fiber reinforced plies are then stacked on a surface of a mold, wetted with a resin, and cured to form at least part of a wind turbine blade. Because the textile-grade PAN fibers are electrically conductive, the resultant structure provides both electrical conductivity and structural integrity. Laboratory testing of carbon fiber structures against simulated lightning strikes demonstrated high resilience due to their high electrical conductivity both in-plane and in through-thickness directions, with no significant damages, e.g., fiber breakage, resin evaporation, or delamination. High-temperature epoxy helped to improve the performance of the CFRP against the lightning strikes.
