NANOTECHNOLOGY FOR FIBER REINFORCED COMPOSITES AND FUTURE DIRECTION- MATRIX SENSITIVE LAMINATE PROPERTIES PREDICTION

摘要

Research on Nanotechnology that impacts the laminates properties of composites will bernpresented. These include addressing the matrix, fiber and the ply level properties. Futurerndirections in modeling development for fiber reinforced composites will be discussed.rnMost micromechanics models are more fiber-centric than matrix centric. That is if onernsubstitutes one fiber with another fiber in a composite structure design, one canrnreasonably predict the changes in laminate properties from the currently availablernmicromechanics models. However, replacing one matrix resin with another, the effect onrnthe laminate properties is not easily predictable. Substantial testing will be required tornaddress the answer to this question. This has been an obstacle to rapid matrixrndevelopment, and prevents achieving future goals of designing materials based on desiredrnend-structure properties/requirements. To address this issue further, there is a lack ofrnlinkage between molecular-scale modeling in a multi-scale modeling framework for fiberrnreinforced composites. This has also prevents the prediction of end laminate propertiesrnbased on changes in resin chemistry and formulations. This issue will be explored asrnpossible future basic research directions for Fiber Reinforced Composite Technology.
