A comparative study of fibre/matrix interface in glass fibre reinforced polyvinylidene fluoride composites

A single fibre pull-out technique was used for interfacial adhesion measurements. The results obtained for MAH-g-PVDF revealed the increased apparent interfacial shear strength by 135% and 75% for the acidic and basic surface fibre, respectively. No changes in interfacial shear strength in case of neutral surface glass fibre were observed. Therefore, better mechanical properties of composites can be achieved by improved interactions between acidic/basic surface glass fibre and MAH-g-PVDF matrix.
