Abstract:

A MOLECULAR MECHANICS COMPUTATIONAL SCHEME IS PROPOSED FOR SIMULATION OF GRAPHITE-POLYPROPYLENE SEMICRYSTALLINE THERMOPLASTIC COMPOSITE. A CELL OF APPROXIMATE DIMENSIONS 18X18X60 A(O) OF GLASSY POLYPROPYLENE BOUNDED BY GRAPHITE ORCRYSTAL ON THE UPPER AND LOWER PLANES IS GENERATED USING KNOWN STRUCTURAL PARAMETERS AND INTERATOMIC POTENTIAL FUNCTIONS FOR POLYPROPYLENE AND GRAPHITE. AFTER GENERATION OF A SUFFICIENT NUMBER OF MICROSTRUCTURES, THE ELASTIC MODULI OF THE COMPOSITE FILM ARE COMPUTED ACCORDING TO THEODOROU-SUTER ALGORITHM. THE SCHEME IS USED TO INVESTIGATE THE EFFECT OF THERMAL EXPANSION MISMATCH AND CRYSTALLIZATION ON THE ELASTIC MODULI. THE SCHEME IS GENERAL AND MAY BE APPLIED TO ANY SEMICRYSTALLINE THERMOPLASTIC COMPOSITE.
