A method is disclosed for reinforcement of thin wall hollow thermoplastic storage vessels with one or more wraps of continuous fibers. This heat-shield mechanism includes a 3-dimensional housing that defines a cavity in which the power source resides, and a plate that is positioned to cover an opening to the cavity that is defined by an edge of the housing. The first p-type layer is sandwiched between the semi-insulating substrate and the first n-type layer. The polymerization is conducted in water and is followed by direct hydrolysis. The backing plate has a cylindrical recess that corresponds to the diameter of the target insert.
