Influence of Processing Parameters on Cobonding-Induced Deformation of Composite Panel with “I”-Shape Stiffener

Article Preview

Abstract:

Composite panels with “I”-shape stiffeners are widely used, but cobonding process induces large warpage deformation after demoulding. Finite element simulation was used in this paper to analyze the effects of some representative processing parameters on the process-induced deformation. The results show that the deformation increases with the consolidation pressure, the CTE of mould and the friction coefficient. The deformation is more sensitive to the consolidation pressure and the friction coefficient for a shorter part, while it is more sensitive to the CTE of mould for a longer part.
