Tool interface pressure during the forming of model composite corners

A new experimental technique is proposed to measure the pressure gradient in corner laminates with aim of guiding manufacturing practices that can produce composites desired thickness. mapping sensor was placed between a metal mould tool and silicone sheet acts as an idealised composite part. The compaction loss internal corners rise external reported for first time, covering part thickness radius ratio 0.2 0.8 corner. conclusive trend observed corners, where drop increases proportionally ratio. thickness, bulk, contact created difficulties measuring true extent corners. Stretchable thin film sensors might provide better alternatives future studies looking investigate gradients doubly curved geometries.
