Title:
STRUCTURE WITH MULTILAYER HONEYCOMB CORE AND MANUFACTURE THEREOF
Document Type and Number:
Japanese Patent JP3152478
Kind Code:
B2
Abstract:
PURPOSE: To manufacture a product having excellent strength without using a molding die by alternately laminating a large number of honeycomb materials and a large number of fiber-reinforced plastic materials respectively and forming a multilayer honeycomb core while fast sticking a skin layer consisting of fiber-reinforced plastics on the surface of the honeycomb core.
CONSTITUTION: A wing-shaped structure 1 is composed of a multilayer honeycomb core 2 and a skin layer 3 fast stuck to the surface of the honeycomb core and covering the surface. The multilayer honeycomb core 2 is formed from a large number of honeycomb materials 21-26 and a large number of fiber-reinforced plastic materials 41-45 disposed at every these layer. Each honeycomb material 21-26 is set thinly in sections, in which comparatively high strength is required, in the structure 1 at that time, and the relative quantities of the fiber-reinforced plastic materials 41-45 in the sections are augmented, thus increasing strength and rigidity. The insides of the honeycomb materials 25, 26 in the end sections (a leading edge section A and a trailing edge section B) of the structure 1 are filed with a resin 5 for reinforcement, thus further augmenting the rigidity of the end sections.
