Abstract

This study considers the effect of prepreg properties on the manual layup process. Commercial prepregs were characterised in terms of shear behaviour, tack and flexural rigidity. The materials were then laid up by professional laminators on a series of increasingly challenging moulds, and the time taken to lay up each material was used as a metric of layup performance. It was found that there is a positive correlation between shear angle and layup time. Considerable differences (up to a factor of 2) in time taken to lay up different materials were also seen. The measured properties were used as predictors in a linear model to determine layup time, where it was found that shear energy and tack are significant. Lastly, some implications for the design and manufacture of composite components are discussed.
