Abstract
The shear behaviour of uncured carbon fibre prepreg is fundamental to avoiding process-induced defects during manufacturing of large-scale components. Shear tests for AS4/8552, are compared to a one-dimensional elastic-plastic model for combined intra-ply shear and inter-ply slip. The paper presents a methodology capable of determining the parameters of temperature and pressure at which minimum resistance to movement for a prepreg exists. Investigating the joint strength and friction values individually shows that friction increases with temperature, contrary to previous work, and that the new value of joint strength is predominant at lower temperatures. Rate dependency arises as an issue to be discussed in future work.
