(5). a) What are sheet-molding compounds (SMC)? Bulk-molding compounds (BMC)? Sheet-molding compound (SMC) is a fiber glass reinforced thermosetting compound in sheet form‚ usually rolled into coils interleaved with plastic film to prevent auto adhesion. Made by dispensing mixed resin‚ fillers‚ maturation agent‚ catalyst and mold release agent onto two moving sheets of polyethylene film. The lower one also contains chopped glass roving or glass mat. SMC can be molded into complex shapes

Compounds First to define the word‚ compounds are pure substances made up of atoms of two or more elements chemically combined together in fixed ratios determined by mass. When a compound is formed from its components‚ a chemical change takes place through chemical reactions. Elements form compounds to become more stable‚ which happens when the maximum number of possible electrons are in the outermost energy level. Carbohydrates: A carbohydrate is one of the elements of the 5 major compounds
