Abstract
A honeycomb structural body includes multiple cores, at least face sheet, and at least one reinforcement sheet. The multiple cores each have a honeycomb structure, and are bonded to each other with foamed adhesive in a direction in which the number of multiple pores formed by the honeycomb structure increases. The at least one face sheet is adhered to the multiple cores so as to cover the multiple pores. The reinforcement sheet is placed between the multiple cores and the at least one face sheet, at a position where the reinforcement sheet covers the foamed adhesive.
Claims16
A honeycomb structural body, comprising:
- multiple cores that have a honeycomb structure, and which are bonded to each other with foamed adhesive in a direction in which the number of multiple pores that is formed by the honeycomb structure is increased;
- at least one face sheet adhered to the multiple cores so as to cover the multiple pores, the at least one face sheet being made of composite material;
- and
- multiple reinforcement sheets each placed on an outer surface side of the at least one face sheet, and at a position where the reinforcement sheets cover the foamed adhesive, the multiple reinforcement sheets being used to reinforce the composite material upon curing,
- wherein the reinforcement sheets are adhered with film adhesive to the at least one face sheet.
A honeycomb structural body, comprising:
- multiple cores that have a honeycomb structure, and which are bonded to each other with foamed adhesive in a direction in which the number of multiple pores that is formed by the honeycomb structure is increased;
- at least one face sheet adhered to the multiple cores so as to cover the multiple pores, the at least one face sheet being made of composite material;
- and
- multiple reinforcement sheets each placed on an outer surface side of the at least one face sheet, and at a position where the reinforcement sheets cover the foamed adhesive, the multiple reinforcement sheets being used to reinforce the composite material upon curing,
- wherein the reinforcement sheets are formed with chamfers.
A method of manufacturing a honeycomb structural body, comprising:
- placing multiple cores that each have a honeycomb structure on both sides of foamed adhesive in a direction in which the number of multiple pores formed by the honeycomb structure is increased;
- placing at least one skin prepreg on the multiple cores so as to cover the multiple pores;
- protecting an outer surface side of the at least one skin prepreg by a bagging film;
- placing multiple reinforcement sheets between the at least one skin prepreg and the bagging film, and at a position where the reinforcement sheets cover the foamed adhesive for reinforcing the at least one skin prepreg upon curing, the reinforcement sheets being adhered with film adhesive to the at least one skin prepreg;
- and
- manufacturing the honeycomb structural body in which the multiple cores are bonded to each other with the foamed adhesive and the at least one skin prepreg that is cured is bonded to the multiple cores, by heating and pressurizing the multiple cores, the at least one skin prepreg, the bagging film, and the reinforcement sheets in a set state.
