CARBON FIBERS AND INTERFACIAL PROPERTIES OF THEIR REINFORCED RESIN MATRIX COMPOSITES

Abstract

Abstract: Surface properties including surface physical morphology,chemical elements and wetting properties of MT700C-6K-42B-1 (abbr． MT700C) and T700SC-12K-50C (abbr． T700SC) carbon fibers were analyzed by SEM、XPS and contact angle analyzer． The interfacial properties of their reinforced resin matrix composites MT700C /603 and T700SC /603 were also studied at dry / hygrothermal ageing conditions． Results show MT700C carbon fibers present better wetting property and stronger adhesion with resin matrix due to higher O/C ratio and active carbon ratio than T700SC carbon fibers． MT700C /603 composite has higher ILSS than T700SC /603 composite at dry and RT conditions． While,through hygrothermal aging,the T700SC /603 composite has better ILSS retention rate than MT700C /603 composite．

Key words: carbon fibers, composites, wetting property, interface
