Composite materials are gaining wide applications in aircraft, spacecraft, automotive and energy generation. For example, in the case of the Boeing 787 Dreamliner, carbon fiber reinforced plastic composites are used for the main structural members. However, their design and analysis still presents challenges due to the multiple scales from micro-level to the structural. For example, for analyzing the deformation of a composite structure, it should be regarded as an anisotropic body at a macroscopic scale. However, to analyze its failure or damage, one must use microscopic analysis with the representative volume elements (RVEs) considering micro cracks in matrix and/or fiber/matrix interfaces. Furthermore, for fabrication and processing of composite structures, the molecular scale at which fiber and resin react also must be considered (i.e. atomistic modeling).
This presentation will introduce the numerical modeling of fiber reinforced plastic composites considering bridging of scales. The studies presented in this presentation are not always tightly connected in a scheme, and each scale is independently modeled in many cases. However, the results from a series of models give us a concise view of how to connect those scales and to use the composite wisely.
This presentation discuss (1) Numerical simulation of interlaminar damage propagation in CFRP cross-ply laminates under transverse loading and impacts, (2) Numerical method for failure simulation of unidirectional fiber reinforced plastic composites, (3) Micromechanics on the rate-dependent fracture of discontinuous fiber reinforced plastic composites, (4) A periodic unit-cell simulation of transverse tensile failures in unidirectional carbon fiber reinforced composites (5) Effect of Nanostructure upon the Deformation Micromechanics of Carbon Fibres and (6) Atomistic simulation of the curing reaction of Epoxy resin.
