DOUBLE SHEAR BONDED JOINT AND METHOD FOR MAKING SAME

Номер: US20170045068A1

Described are channel joints () for bonding a tube or tubular member () to an end fitting () in double shear. The channel joint may include a receiving channel () in the end fitting () that is complementary in shape to the tube, tubular member, or other hollow member () 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 (). 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. The resulting joint is less likely to have voids, has additional bonding area compared to lap joints, and prevents the adhesive or bonding agent from experiencing tensile loads. 1. A bonded joint comprising:a hollow member comprising a wall, the wall having a wall thickness;a receiving member comprising a receiving channel of complementary shape to the hollow member comprising a channel width;wherein the channel width is greater than the wall thickness;the hollow member disposed at least partially within the receiving channel; andthe hollow member secured within the receiving channel by a bonding agent.2.

In a method of printing a transferable component, a stamp including an elastomeric post having three-dimensional relief features protruding from a surface thereof is pressed against a component on a donor substrate with a first pressure that is sufficient to mechanically deform the relief features and a region of the post between the relief features to contact the component over a first contact area. The stamp is retracted from the donor substrate such that the component is adhered to the stamp. The stamp including the component adhered thereto is pressed against a receiving substrate with a second pressure that is less than the first pressure to contact the component over a second contact area that is smaller than the first contact area. The stamp is then retracted from the receiving substrate to delaminate the component from the stamp and print the component onto the receiving substrate. Related apparatus and stamps are also discussed. 1. An elastomeric stamp , comprising:a deformable elastomeric layer including a post protruding therefrom, the post having an elastomeric surface configured for contact with a transferable component, wherein the elastomeric surface includes a plurality of three-dimensional relief features protruding therefrom, wherein at least a portion of the relief features and a region of the post between the relief features are mechanically deformed when the post is pressed against a transferable component at a first pressure so that the post contacts the transferable component over a first contact area, and wherein the post contacts the transferable component over a second contact area smaller than the first contact area when the post is pressed against the transferable component at a second pressure less than the first pressure.2.
