The Relationship

A systematic study has been conducted to investigate the influence of silane treatment on the interfacial shear strength of glass fibre/epoxy composites by means of microbond tests, and to clarify the relationship between the interphase consisting of physisorbed and chemisorbed silanes on glass fibre surfaces and the corresponding interfacial shear strength.

Transfer Models

A model has been proposed that represents the compressive fragmentation phenomenon and can evaluate the interfacial shear strength without recourse to complicated stress transfer models. The temperature dependence of the interfacial shear strength is investigated for carbon fibre-polycarbonate microcomposites and the values obtained are applicable to a system that has weak interfacial bonding.

AbstractFibre-reinforced cements are proving to be useful in various oilfield applications. Low cost and increased toughness render glass fibre reinforced cements of particular interest. In most cases, improvements in toughness are the result of extensive fibre pull-out and this can be clearly observed in electron micrographs of fracture surfaces. This observation implies that there is much scope for improving the interfacial shear strength between the hydrated cement and glass fibres.Experiments have shown that increases in flexural strength and in energy to fracture can be achieved by incorporating small amounts of a polymer latex. Improvements of a factor of four in energy to fracture have been measured when approximately 0.8% by volume of a styrenebutadiene copolymer latex is added to a glass fibre reinforced class G oilwell cement. Experimental results suggest that this effect is not due to improvements in the strength of the cement matrix but due to an enhancement of the interfacial shear strength between fibre and cement.
