Abstract:

The objectives of this research are a To demonstrate the feasibility of processing novel transparent interpenetrating polymer networks by combining stiff and compliant polymeric constituents and b To mechanically characterize them under impact loading conditions. On the material processing front, novel polymer systems termed Molecular Interpenetrated Polymer Composites MIPC comprising of two or more networks are partially interlaced at the molecular scale to produce sheet stock. By manipulating the reaction kinetics MIPCs are tailored topossess good optical transparency as well as improved mechanical characteristics. On the mechanical characterization front, high-strain rate failure characterization of MIPCs is critical for armor applications. Hence techniques capable of characterizing MIPCs by exploiting their optical transparency would be of great value. Accordingly, a novel, non-contact, full-field deformation measurement method to investigate fracture and failure of monolithic and layered transparent sheets under stress-wave loading conditions is developed.
