Structurally Engineered Molding Compounds refers to a class of material and its interdependency on the design elements of the material structure. Specifically the selective use of continuous fiber uni-directional and woven reinforcement locally introduced into a parent structure consisting of a chopped random fiber reinforcement. This ‘Engineering’ allows the strength and stiffness characteristics of an SEMC structure to be comparable with a continuous fiber reinforced composite without incurring the typical cost of that type of structure.
