Abstract
Composite structures consisting of galvanized steel wire as a fiber and low density polyethylene as a thermoplastic matrix were manufactured by hot-press molding. The mechanical properties were experimentally determined. The effect of orientation angle and symmetric-antisymmetric structure was investigated under in-plane forces. An elastic-plastic numerical solution was carried out using finite element modeling (FEM) for some iteration numbers. Residual stresses and expansion of plastic zone have been illustrated in tables and figures.
Highlights
Composite materials offer great potential and flexibility in structural design because of the anisotropy of material properties, unique ply-by-ply constructions, and novel fabrication methods (Alexander and Tzeng, 1997)
A number of papers have appeared on stress analysis of fibrous composite structures
The metal matrix laminated plate of constant thickness is composed of orthotropic layers bonded symmetrically or antisymmetrically about the middle surface
Summary
Composite materials offer great potential and flexibility in structural design because of the anisotropy of material properties, unique ply-by-ply constructions, and novel fabrication methods (Alexander and Tzeng, 1997). G., Torlon, PEEK and Ryton, followed by numerous other candidates, as matrix materials in structural composites have given another dimension to the advanced application of reinforced plastic materials (Chen et al, 1993.). This new generation of engineering materials, thermoplastic polymer matrix continuous fiber composites, offer the potential of significant improvement and advantage in many aspects, compared with conventional reinforced thermosets (Hoggatt, 1973, 1975; Hartness, 1980, 1982, 1984; Rigby, 1982; Hergenrother et all., 1984; Muzzy and Kays, 1984). Prediction and measurement of residual stresses are important in the production, design and performance of composite component (Karakuzu et all., 1997)
