Abstract

Varying part dimensions usually result in reduced usable material properties. The dependence of the resultant part properties with reduced part dimensions associated with fibre reinforcement is largely uninvestigated. This paper discusses the interactions between different part dimensions and varying short glass fibre reinforcement. The results show that fibre reinforcement can favour the use of mechanical material properties. However, the amount is dependent of the fibre content and the part dimensions available.
