Abstract

A plurality of fibre surface modifications were assessed in the context of improving interfacial bonding of aramid fibres in Pebax 7033 matrices. Characterisation by optical and atomic force microscopy, differential scanning calorimetry and raman spectroscopy show that varied surface treatments for aramid fibres, with all other parameters constant, will affect the degree of transcrystallinity (TC) in the composite. Fibre surface modifications showed improvements in interfacial properties, especially in reducing the critical fibre fragment length.Quantitative analysis demonstrates improvements in the fibre-matrix interface suggesting a qualitative interdependency between the degree of TC and interfacial composite properties.
