Abstract

In this works, a glow discharge cold plasma treatment was employed to treat organic and inorganic fibre (aramid , polyethylene and glass fibres) with the aim to improve the fibre-matrix interface properties. In order to quantitatively assess the effect of plasma treatment, treated and untreated fibres were used to fabricate specimens suitable for mechanical test characterisation. Peeling test and three-point bending tests were performed on untreated and treated specimens. Scanning electron microscopy was utilised to examine the plasma effects on the fibres surface and on the specimen fracture surfaces. The results obtained indicate that the interface strength depends of both the fibre type and the treatment time. In all cases, an increase in delamination energy was observed under appropriate treatment conditions. SEM analysis had shoved variation in the fibres roughens Although this last result, the measured Young’s modulus and flexural strength do not undergo any decrease, whichever the exposure time
