Investigation of Some Basic Properties of Hybrid Composite Materials

摘要

This final report presents the major findings of research for the investigation of some basic properties of hybrid composite materials. The topics covered in this study were: (1) Statistical strength theory of continuous fiber composites; (2) Non-linear stress strain behavior of hybrid composites; (3) Two-dimensional fabric composites: 3.1 woven hybrid composites, 3.2 notched strength of woven fabric composites with molded-in holes, 3.3 friction and wear of advanced thermoplastic composites, 3.4 impact behavior and damage tolerance of woven carbon fiber reinforced advance thermoplastic composites. (4) Flexural and axial compressible failures of three-dimensionally braided composite I-beams. (5) Three-dimensional analysis of transient interlaminar thermal stress of cross-ply composites. Keywords: Fiber composites, Fiber Hybridization, Statistical strength theory, Woven fabric composites, Notched strength, Friction and wear, Impact, Damage tolerance, Residual strength.
