Core Molding Technologies Inc. (Columbus, Ohio, USA), a North American compounder of custom sheet molding compound (SMC), has developed a low-density SMC with high surface quality and improved economics over previous low-density materials offered by the company. The Featherlite brand of SMC has a nominal density 25 percent less than the density of industry-standard SMC formulations. The material offers good toughness and is said to be ideal for high-impact applications where the strength of a glass-reinforced composite is also required. Because the material achieves lower density without the use of glass microspheres, it reportedly reduces the risk of “paint pops” in Class A applications and offers high surface quality not typical of SMC products in this density range.
Editor PickStrata, Reliance form partnership to advance aerospace composites
The partnership will look at opportunities in the production of carbon fiber aerostructures, prepegs as well as 3D printing of aerospace components and airframe panels.
