Design and simulation analysis of pressing molding mould for remoulding CFRP stiffened panel
The design and manufacturing process of the hot bending moulding mould of a kind of carbon fiber reinforced Vitrimer resin matrix composite material were introduced for T-shaped stiffened panel,the hot bending moulding process of T-shaped stiffened panel was described from the aspects of the shape size of T-shaped stiffened panel,mould design,temperature field and ther-mal deformation check,the effect of hot bending moulding of T-shaped stiffened panel with Vitri-mer resin matrix composite was introduced by experiments and production practice,and the key dimensions and apparent state of the moulded parts were examined and evaluated,and the all could meet the requirements.The design of the mould structure could realize the uniform heat transfer and high-precision molding of Vitrimer resin matrix composite parts in the process of hot bending moulding,which could reduce the stress concentration caused by the product thermal de-formation and improved the product production efficiency and the product yield.
