Abstract

If components are manufactured from compression moulded fibre reinforced material then the flow of the material during the moulding process complicates any analysis as the resultant material properties are not constant throughout the component. This paper presents some of the work carried out in a comparative study of notched plates manufactured from sheet moulding compound (SMC) subjected to a uniaxial tensile load. Two techniques have been used (i) the experimental thermoelastic stress analysis technique based on the SPATE equipment, and (ii) a numerical finite element technique with data from a flow modelling programme. The notched plates were manufactured using two different "charge" positions so that different degrees of fibre alignment and material anisotropy were developed during the moulding process. The experimental and numerical results are compared and useful conclusions are drawn for further work in this important area.
