Title:
METHOD FOR FORMING HONEYCOMB SANDWICH COMPOSITE MATERIAL AND JIG USED THEREFOR
Document Type and Number:
WIPO Patent Application WO/2019/171683
Kind Code:
A1
Abstract:
Provided is a technique for forming a honeycomb sandwich composite material which is easy and can be automated. The honeycomb sandwich composite material 30 comprises a honeycomb core 20, an FRP lower portion provided on the honeycomb core lower surface, and an FRP upper portion provided on the honeycomb core upper surface. A first prepreg sheet laminate 21 serves as the fiber-reinforced plastic upper portion. A second prepreg sheet laminate 22 serves as the fiber-reinforced plastic lower portion. A jig 10 having a trough 11 corresponding to the upside-down shape of the honeycomb 20 is used in the shaping step and the curing step. The first prepreg sheet laminate 21 is shaped so as to correspond to the trough 11 by a hot drape device (S15), the honeycomb core is disposed upside-down (S16), and the second prepreg sheet laminate 22 is placed thereon (S17). Without removing the mold, curing is effected by applying high temperature and high pressure by an autoclave device, the mold is removed after curing, and the composite material is turned upside-down.
