Carbon Fiber Reinforced Sheet Molding Compound (SMC) Epoxy is a subcategory of Epoxy. The additative is added during the manufacturing process. Its tensile strength ranges from 40000 to 50000 MPa at break. Its flexural strength ranges from 75000 to 95000 MPa. Its compressive strength ranges from 30000 to 40000 MPa. Its Izod Impact strength ranges from 15 to 20 J/cm. Its elongation at break ranges from 0.5 to 2 %. Its hardness ranges from 55 to 65 Shore B. Its molding pressure ranges from 0.5 to 2 MPa.

Epoxy is a thermoset polyadduct. Common trade names include Acme, Aerolam, Basoset, Beckopx, Conapoxy, Corlar, Cycom, DER, Desmobond, Dobeckot, Dynopon, Ecco, Epikote, Epocast, Epodite, Eprosin, Eurepox, Exatron, Grilonit, Hysol, Isochembond, Lekutherm, Lopox, Nikalet, Paraplex, Quartrex, Scotchcast, and Synthane. Epoxy possesses many useful properties: air curable, highly fillable, low shrinkage, low susceptibility to stress formation, good adhesion to almost all materials, high tensile and vibrational strength, high heat resistance, high heat deformation resistance, high chemical attack resistance, good aging properties, good electrical and dielectrical properties, odorless, tasteless, and low flammability. Epoxy is commonly used in adhesives and reactive molding compounds. Epoxy is a copolymer, which means it is formed from two different chemicals, usually referred to as the "resin" and the "hardener". Epoxy-based materials can be used for coatings, adhesives, composite materials, mold making, and electrical insulators. When working with epoxy, vinegar is an effective and safe solvent for cleaning epoxy resins from tools, brushes, skin, and most surfaces.
