摘要： A method for imparting textures of grained or woven patterns to the surfaces of thermoset articles during the formation of the article includes a platen with a texture being introduced into a mold. A thermoset material is charged into the mold. Pressure and heat are applied to bring the thermoset material into contact with the platen to impart the texture to a surface of the thermoset material. The thermoset material is allowed to cure in the mold. The thermoset article is removed from the mold with the texture. The textured article is structurally improved relative to a like article formed with a smooth or other platen texture. A system for producing the article by way of the method is also provided.

摘要： A process is provided to reclaim carbon fiber from a cured vinyl ester, crosslinked unsaturated polyester, or epoxy thermoset matrix. The composite pieces are added to a polyol solvent composition under to conditions to free more than 95% by weight of the carbon fiber from the composite. The freed carbon fibers are washed and dried to reclaim carbon fiber reusable to reinforce a polymer to form a new FRC article. Solvents are chosen that are low cost and low toxicity. Processing is further facilitated by techniques such as solvent pre-swell of the particles, microwave heating, and sonication to promote thermoset matrix digestion to free reinforcing carbon fibers.

摘要： A process of compression molding an article from a curable resin is provided that includes opening a mold to an open position by displacing an upper die having an upper mold surface from a lower die having a lower mold surface. Resin is placed a mold surface and the dies are closed to an intermediate start position at a rate of from 1 to 10 cm/sec. The dies are then closed to a start position at a rate of between 25 and 60% of the rate of closure to the intermediate position. A shroud volume is evacuated for at least 3 seconds to a reduced pressure of less than 0.16 atmospheres while continuing to press toward a mold cavity volume at a rate of between 12 and 30% of the rate of closure to the intermediate start. The reduced pressure is removed as the full compression is applied.
