Popis: | The effect of the surrounding liquid on the strength of the polymer/fibre interface was studied. For this purpose, the shear adhesive strength, τ, between an epoxy composition EDT-10 (based on diglycidyl ether of bisphenol A) and a steel wire of diameter 150 μm was tested by the pull-out technique at 20°C. Loading of the speciments was made in water, ethanol, and in their mixtures of different composition, i.e. in polar liquids with different surface tension γ: (23.5⩽γ⩽72) mN m −1 . It was shown from loading the epoxy/steel wire joints in these liquids that their adhesive strength is lower than the adhesive strength of the specimens tested in air. The losses in adhesive strength do not depend on the surface tension of the surrounding liquids under investigation. The possible mechanisms of the strength decrease are discussed. |
