Failsafe injected adhesive joint
First Claim
1. A method of securing two members to each other, comprising:
- (a) providing each of the members with a bonding surface;
(b) forming elongated recesses in each of the bonding surfaces that mate with each other to define a cavity;
(c) placing the bonding surfaces against each other;
then(d) injecting adhesive into the cavity and curing the adhesive.

Abstract
A composite member is joined to another composite or noncomposite member, using liquid or paste adhesive resin that cures in the joint. The joint is configured in such a way that the adhesive forms an interlocking key within recesses in the joined members that prevents joint disassembly once the adhesive has cured and hardened. Both of the members are provided with recesses extending along their lengths in the joint. The recesses register with each other to define a cavity and may undulate. The recessed are designed in such a way as to take the full load capability if the joint, even if there is no adhesion to the joined members. Adhesive is injected into the cavity through injection ports spaced periodically along the length of the joint.

7. A method of joining a structural member to an aircraft skin, comprising:
-
(a) providing the structural member with a recess extending lengthwise along the first member; (b) providing an interface member with a base and a leg, the leg having a recess extending lengthwise along the interface member; (c) placing the structural member and the interface member against each other so that the recesses mate to define a cavity; (d) injecting adhesive into the cavity; and (e) bonding the structural member to the skin. - View Dependent Claims (8, 9, 10, 11, 12, 13)

14. A method of joining a structural member to an aircraft skin, comprising:
-
(a) providing the structural member with a pair of recesses, the recesses being on opposite sides of the structural member and extending lengthwise along the structural member; (b) providing an interface member having a base and a pair of legs extending orthogonally therefrom, each of the legs having an inside surface with a recess extending lengthwise along the interface member; (c) inserting the structural member between the legs, the recesses of the structural member aligning with the recesses of the legs to define elongated cavities; (d) injecting adhesive into each of the cavities;
then(e) curing the adhesive and thereby bonding the interface member to the skin. - View Dependent Claims (15, 16, 17, 18, 19, 20)
