Stress modelling in curved parts of short fibres reinforced plastic products

Abstract

An investigation was carried out through a study of the influence of material anisotropy of the rounded corners of thin-walled plastic injection molded products reinforced by short-fibres, on the state of stress. It has been shown that the result of such injection-moulded processes is an anisotropic and layered product, whose mechanical behaviour differs for that of isotropic and homogenous solids. Unlike unreinforced plastics, fibre composites exhibit secondary stress effects thus need to be careful consideration in the course in designing of short fibres reinforced plastic products. © (2014) Trans Tech Publications, Switzerland.
