Role of Tool-Part Interaction in Consolidation of L-Shaped Laminates during Autoclave Process

Abstract

The role of tool-part interaction in the consolidation process of the L-shaped laminate was studied using a finite element model. The tool-part shear actions during processing were modeled by introducing shear layers. The predicted data demonstrate the necessity of considering the slippage between the tools and the laminate in simulations. A parametric study examining the effects of the shear layer properties on the compacting behavior was performed and the results show that improving the slippage ability of the male mold upon the composite part is of advantage to apply the pressure on the corner section of the L-shaped laminate. Moreover, the mechanical properties and the thickness of the shear layer have a significant influence on the modeling of the consolidation process.
