Abstract

A method for bonding a plurality of non-magnetic members includes the steps of (1) mating the non-magnetic members via an uncured adhesive interposed between their surfaces to be bonded; (2) applying pressure to their mated portions between a pressing magnet jig and a pressure-receiving, soft-magnetic jig; and (3) curing the adhesive while applying pressure.

Claims

1. A method for bonding a plurality of non-magnetic members comprising the steps of:

(1) mating non-magnetic members via an uncured adhesive interposed between their surfaces to be bonded;

(2) applying pressure to the mated portions of said non-magnetic members between a pressing magnet jig and a pressure-receiving, soft-magnetic jig; and

(3) curing said adhesive while applying pressure.

2. The method for bonding a plurality of non-magnetic members according to claim 1, wherein said adhesive is a thermosetting adhesive in the form of a sheet.

3. The method for bonding a plurality of non-magnetic members according to claim 1, wherein a cushioning member is interposed between a pressing surface of said pressing magnet jig and outside surfaces of the mated portions of said non-magnetic members.

4. The method for bonding a plurality of non-magnetic members according to claim 2, wherein a cushioning member is interposed between a pressing surface of said pressing magnet jig and outside surfaces of the mated portions of said non-magnetic members.

5. The method for bonding a plurality of non-magnetic members according to claim 1, wherein said non-magnetic members are made of a fiber-reinforced composite material.

6. The method for bonding a plurality of non-magnetic members according to claim 1, wherein a pair of non-magnetic members are bonded together, and said non-magnetic members are half-cylindrical skin members made of a fiber-reinforced composite material for constituting a fuselage of aircraft.
