A Tentative Interpretation of the CFRP Mechanical Characteristics Based Upon the Fibre/Matrix Relations at the Interface. A Case Study

Materials selection aimed at structural applications calls for notions of “efficiency factor” and “fibre/resin matching” that are based mainly upon a comparison of the constituents characteristics with those of the corresponding moulded composites. It is shown in the presentation that a full a better knowledge of the fibre/matrix relation at the interface. Example is taken of two widely used carbon fibres (T300 and AS4) associated with the Ciba 914 resin.
