11/4/2022 0 Comments Diaposheet![]() The discontinuous nature of the reinforcement allows these materials to be molded into complex geometries by compression molding processes. Reinforced with 40% - 65% discontinuous glass fiber, this high level of reinforcement imparts high strength and impact resistance to these composite materials. They are not intended to have superior color properties but will provide a suitable surface for adhesion and surface quality. These composite materials exhibit a minimal expansion characteristic. These materials are intended for use in automotive or transportation body panels that require painting. From UL 94 V0 and 5VA to the Bonfire testing levels, we work with customers to identify the flame performance level best suited for their application. IDI's Flamevex ™ materials offer a range of flame performance levels that can be tailored to an OEMs requirements. IDI also offers carbon fiber reinforcement for applications that require exceptional strength coupled with severe weight restrictions in our Structural Thermoset line of products.įor more information, on Sheet Molding Compounds and Bulk Molding Compounds. Fiber Lengths range from 1/32-inch in BMC up to 1-inch in some SMC's, resulting in various strength characteristics which can be customized for individual needs. ![]() ![]() SMC uses slightly longer length fibers than BMC, and typically has a higher percentage of reinforcement fibers than BMC. For instance, design engineers might choose vinyl ester resin for corrosion-resistant products, epoxy resin for high-strength applications, or polyester resin when good overall performance and cost are the driving factors.īulk Molding Compounds (BMC) and Sheet Molding Compounds (SMC) are both fiber reinforced materials, typically utilizing glass strand fibers of varying lengths. Each of these resins has its own price and performance characteristics, so selection is based on the functional and cost requirements of the application. The most common thermoset resins are polyester, vinyl ester, polyurethane, and epoxy. ![]()
