The Concept of One Polymer Composites Modeled with High Density Polyethylene.
Abstract
The effort described here is to present a novel idea in reinforced polymeric materials, the one polymer composite. This corresponds to a composite in which the matrix and reinforcement are made from different morphologies of the same polymer. As a model case, polyethylene has been used through this study; the results, nonetheless, may be generally extended to other semicrystalline thermoplastics. High modulus polyethylene fiber and film strips have been prepared by a solid-state (crystal-crystal) transformation. The resulting morphology has been subjected to intense characterization. Important characteristics of these fibers and film strips are their optical transparency and their high and time and temperature insensitive Young's moduli. Typical melting endotherms for the oriented fiber and the starting polyethylene, are shown. The melting point difference between the fiber and matrix is the defining feature for the one polymer composite. The melting point difference makes possible the dispersion of the polyethylene fibers in the melt of the polyethylene matrix.
