Abstract

It is often suggested that optimization of the fibre-matrix interfacial adhesion is essential to improve the mechanical performance of natural fibre reinforced thermoplastic compounds. The use of such composites in many applications often requires characterisation of performance over a range of temperatures. This paper presents a study on the measurements of the interfacial adhesion of coir fibre with various polyolefin matrices at room temperature. We then present a novel adaptation of a dynamical mechanical analyser to enable the measurement of interfacial shear strength over the temperature range of −40°C to 120°C. Results from these measurements are presented and discussed in terms of the relationship of apparent IFSS to residual thermal stresses in such thermoplastic composites.
