Abstract
Channel joints (1) can permit bonding a tube or tubular member (30) to an end fitting (20) in double shear. The channel joint may include a receiving channel (25) in the end fitting (20) that is complementary in shape to the tube, tubular member, or other hollow member (30) that is to be fitted and bonded with the end fitting. The use of a channel joint allows for simplified assembly because the receiving channel acts as a reservoir for the bonding agent or adhesive (50). Upon insertion of the tube, tubular member, or other hollow member into the adhesive-loaded receiving channel, the adhesive will backflow to fill the voids in the joint and expel the excess adhesive.
Claims22
A bonded joint comprising:
- a hollow member formed of a first material and comprising a wall, the wall having a wall thickness;
- a monolithic receiving member formed of a second material and comprising a receiving channel of complementary shape to the hollow member, the monolithic receiving member comprising an inner channel surface, an outer channel surface, and a channel width, wherein:
- the first material and the second material are subject to corrosion when placed in contact with each other;
- the channel width is greater than the wall thickness;
- at least one of the inner channel surface or the outer channel surface comprises a continuous linear taper along a full length thereof such that the channel width has a maximum value at an opening of the receiving channel and a minimum value at an end of the receiving channel;
- the hollow member is disposed at least partially within the receiving channel;
- the hollow member is secured within the receiving channel by a bonding agent that provides a barrier against corrosion between the first and second materials;
- and
- the inner channel surface and the outer channel surface comprise symmetric continuous linear tapers along full lengths thereof.
A method of manufacturing a bonded joint, the method comprising:
- providing a hollow member formed of a first material;
- providing a monolithic receiving member formed of a second material, wherein the first material and the second material are subject to corrosion when placed in contact with each other;
- forming a receiving channel in the monolithic receiving member complementary in shape to the hollow member;
- injecting a bonding agent into the receiving channel and that provides a barrier against corrosion between the first and second materials;
- and
- inserting the hollow member at least partially into the receiving channel, wherein the receiving channel comprises a channel width with a continuous linear taper along a full length thereof such that the channel width has a maximum value at an opening of the receiving channel and a minimum value at an end of the receiving channel, wherein an inner channel surface and an outer channel surface of the receiving channel each comprise symmetric continuous linear tapers along full lengths thereof.
