**Abstract**
 Improvements in the interfacial adhesion of glass fibre reinforced polypropylene by heat treatment, was studied. Polypropylene was blended with glass fibres and injection moulded. The moulded parts were treated at various temperatures for various times, and characterisation of the mechanical properties of the resulting samples was performed including measurement of the critical fibre length, and by means of differential scanning calorimetry. Results show that the critical fibre length increases while the tensile strength decreased with increasing testing temperature. At 25 and 80 degrees C, heat treatment is shown to improve tensile strength, but that at or above 120 degrees C, certain treatment conditions cause the tensile strength to decrease significantly. 32 refs.
