MULTI-SCALE INTERFACE SIMULATION RESEARCH AND DEVELOPMENT OF FIBER REINFORCED RESIN COMPOSITES

纤维增强树脂基复合材料作为轻量化结构材料,被广泛应用在各行各业,其界面设计与调控研究也受到人们的广泛关注。然而,传统的实验表征很难解释复杂的平衡态/非平衡态界面作用机理,计算机模拟技术作为其补充,在构效关系可视化方面展现了强大的优越性。本文从微观、宏观以及跨尺度三个方面综述了纤维增强树脂基复合材料界面的建模方法和作用机理及其对材料力学性能、热力学性能、动力学性能等的影响,并提出了计算机模拟技术在未来高性能复合材料研发中的指导意义和发展趋势。

Nowadays,fiber reinforced resin matrix composites are widely applied in various industries as lightweight structural materials,and the design and research of interface have also attracted people′s widespread attention as the Achilles′heel of composite materials.The traditional experimental characterization methods are difficult to explain the complex equilibrium/non-equilibrium interface interaction mechanism,but computer simulation technology shows strong superiority in the visualization of interface interaction mechanisms and the description of quantitative structure-activity relationship(QSAR).In this paper,the modeling methodology and the mechanism of interface of fiber reinforced resin composites and its effect on mechanical properties,thermodynamic properties and kinetic properties of materials are in hierarchical order,including perspectives from microscale,macroscale,and cross-scale,and this article proposes the guiding significance of computer simulation technology for cross-scale constitutive parameters,nonlinear friction dissipation mechanisms,high strengthening and toughening mechanisms,and high-throughput prediction and screening which represent the trends in future development of high-performance composites.
