Document Type and Number:
WIPO Patent Application WO/2024/043318
Kind Code:
A1
Abstract:
Provided is a novel method for manufacturing a honeycomb sandwich structure in which a honeycomb core is sandwiched between CFRP layers. The method comprises: (i) charging a mold for primary molding with a honeycomb core and at least two first prepregs; (ii) obtaining a primary molded article of a honeycomb sandwich structure in which the honeycomb core is sandwiched between two first CFRP layers by pressurizing and heating the charged mold for primary molding with a press machine; (iii) charging a mold for secondary molding with the primary molded article and at least two second prepregs; and (iv) obtaining a secondary molded article of the honeycomb sandwich structure in which the honeycomb core is sandwiched between the two first CFRP layers and second CFRP layers are stacked on the two respective first CFRP layers by pressurizing and heating the charged mold for secondary molding with the press machine.
