Questions about Thermoset Composites?

STC®

Structural Thermoset Composites
Structural thermosets are high-performance composites that are distinguished from standard compounds by the use of more specialized resins both liquid and solid (vinylester, epoxy, benzoxazine, etc.) combined with higher levels of reinforcement (glass, carbon, natural, etc.).

SMC

Sheet Molding Compounds
SMC is a combination of long chopped glass strands, mineral fillers and liquid thermosetting resin in the form of a malleable sheet material. Processing of SMC of is typically done by compression or injection molding.

BMC

Bulk Molding Compounds
BMC is a combination of short chopped glass strands, mineral fillers and liquid thermosetting resin in the form of a bulk material. BMC is suitable for either compression or injection molding.

Structural Thermoset Composites Address High Performance Applications

High Strength Thermoset CompositesStructural thermosets are high performance composites that are distinguished from standard SMC and BMC by the use of more specialized resins combined with higher levels of reinforcement (glass, carbon, aramid, etc.). The resulting fiber reinforced composite material satisfies unique performance requirements. Structural thermosets improve the design, manufacture, and durability of a broad range of products, causing many design engineers and molders to convert their product designs to Structural Thermoset SMC and Structural Thermoset BMC. Consisting of fiber-reinforced polymers with cross-linked molecules, these products offer a number of advantages over metals and thermoplastics, including higher strength per unit weight, better dimensional stability and corrosion resistance, greater design flexibility, and lower overall costs.


comparison of Structural Thermoset Composites to competing materials

Markets such as Military & Aerospace, Transportation, Safety, Medical, Electrical, Oil & Gas, Alternative Energy, and Marine rely increasingly on Structural Thermoset SMC and BMC technology to address growing demands for high-reliability metal replacement materials. Due to the intrinsic limitations of metals and thermoplastics, many designers turn to structural thermosets to provide greater strength, lower coefficients of thermal expansion, and better corrosion resistance than other commonly used materials, while increasing design flexibility and manufacturing efficiency. The strong molecular bonds inherent in high-performance thermoset compounds impart a tight web of inner connectivity that provides these materials with the ability to maintain excellent structural properties during prolonged exposure to extreme chemical and temperature profiles.
