This paper addresses the damage modeling, damage characterization, and optimization issues in discontinuous fiber polymer composites. Damage modeling is achieved using a multiscale mechanistic approach which accounts for the damage mechanisms in addition to the constituents’ properties and characteristics. Acoustic emission techniques are applied to characterize the type and accumulations of damage under quasi-static and cyclic loading. Optimization of the composite microstructure that better distributes the micro-features (i.e. fiber orientation, aspect ratio, volume fraction) is performed using an optimal control theory approach.
