Abstract
Single fiber pull-out tests were conducted for G34-700/ Araldite-F, T700S/Araldite-F and T800H/Araldite-F model composites using an improved experimental set-up to evaluate the interfacial shear strength (IFSS). The modified method made it possible to reduce the formation of resin meniscusand to accurately define the embedded fibre length, and it also provided a practical approach to conveniently estimate the IFSS for comparison of the fibre-matrix adhesion between different composite systems or different fibre surface conditions. A strong interfacial adhesion and unstabledebonding process without detectable friction stages were found for all types of model composites with fibres being chemically treated/sized or sizing being removed. The electrochemical oxidation treatment and sizing on the carbon fibres noticeably increase the IFSS of the composites.
