Introduction:SMC, or Sheet Molding Compound, is a composite material comprising long carbon or glass fibers dispersed in a resin bath of vinyl ester, polyester, or epoxy. This combination results in a robust final product known for its strength. Typically sold in rolls, SMC can be cut into smaller pieces called "charges" for various applications. Production involves integrating the fibers and resin by applying resin paste to a film, adding cut fibers, and compressing the mixture between two films. After storage to achieve the desired texture, compression molding applies heat and pressure to cure the SMC, yielding the finished product.
