    In this study Micro-Raman spectroscopy, with the ability to measure strains in graphite fibers with a spatial resolution of 2m, was used to measure fiber strain and monitor fiber interactions in model multi-fiber graphite/epoxy composites.

[Donald O Thompson; Dale E Chimenti;] -- This volume (Parts A and B) contains edited papers presented at the annual Review of Progress in Quantitative Nondestructive Evaluation held at the Fort Magruder Inn, Williamsburg, Virginia, June.

    Thus composites designers will gain an understanding of the causes of material performance, allowing them a wider choice of materials than might otherwise be possible. Secondly, the book describes composites manufacturing methods, providing tips for getting the best results that weigh the required material properties against cost and production. An attempt is made to rationalize the fracture behavior of pearlitic gray irons on both the microstructural and macrostructural levels. Along with the effects of inoculation, those of as-cast section size and carbon equivalent may be rationalized on the basis of coarseness and volume fraction of the weak graphite flakes present in the structure based upon Hornbogen and Motz Author: D. K. Verma, J. T. Berry.

      Exothermic heat generation due to the epoxy resin’s chemical reaction is included as a function of temperature and degree of cure. Numerical simulations using a control-volume-based finite difference method are run for a common graphite/epoxy (AS4/) by: Thesis title, Impact and Post-Impact Response of Kevlar/Epoxy and Graphite/Epoxy Structures. Research included the development of a consistent analytical and experimental design approach for assessing the impact response, the damage produced from impact, and the post-impact residual strength of advanced composite structures.
