Sandwich panel joints and methods for joining sandwich panels
Joints for joining panels together, such as for joining honeycomb sandwich panels used in aerospace applications, and methods of joining said panels are disclosed. In some examples of disclosed joints, a first panel and a second panel can be joined together to form a joint. The first panel can be a flat panel that includes a rabbet formed along a first longitudinal edge, and the second panel can be a curved panel that includes a notch formed along a second longitudinal edge. In forming the joint, a portion of the rabbet can be positioned within the notch, and the flat panel and curved panel can be oriented at a non-parallel and non-perpendicular angle to one another. Adhesive can be applied along the rabbet and/or the notch in order to secure the joint.

Flexible golf club grip with stable cap
A flexible elastomeric grip for the shaft of a golf club having an end cap with a cavity for receiving a sensor and/or counterweight. The cap has a durometer hardness equal to or greater than the tubular body portion of the grip and a flange sized to match the larger diameter of the body, with a sleeve engaging the inner periphery of the larger end of the tubular body. In one version of the cap, the sleeve portion is extended in length and has stiffening ribs on the outer surface of the sleeve; and, in another version, the sleeve is shorter and may also have stiffening ribs on the outer surface of the sleeve. In another version of the cap, fibrous material is disposed in the flange and sleeve to increase lateral stiffness without increasing durometer.
Crown reinforcement for an aircraft tire
Crown reinforcement of an aircraft tire comprises a working reinforcement (2) radially inside of tread (3) and radially outside of carcass reinforcement (4). Working reinforcement (2) comprises two working bi-plies (21, 22) radially superposed with respective axial widths (L.sub.1, L.sub.2), from first axial end (I.sub.1, I.sub.2) to second axial end (I.sub.1, I.sub.2). Each working bi-ply (21, 22) comprises two working layers (211, 212; 221, 222) radially superposed and respectively made up of axially juxtaposed portions of strip (5) of axial width W extending circumferentially in periodic curve (6) that forms, in the equatorial plane (XZ) of the tire and with the circumferential direction (XX) of the tire, a non-zero angle A and has a radius of curvature R at its extrema (7). The difference DL between the respective axial widths (L.sub.1, L.sub.2) of the radially superposed working bi-plies (21, 22) is at least equal to 2(W+(RW/2)(1cos A)).
Method for obtaining a welded joint between elements of different materials, and a hybrid component obtained through this method
A welded joint between at least one metal material element and at least one thermoplastic material element is obtained by pressing the elements against each other while applying heat. Contact surfaces of the metal material, which are in contact with the thermoplastic material, are provided with uneven surface portions having a distribution of asperities. With heat applied, the thermoplastic material fills spaces between these asperities and maintains this configuration after subsequent cooling, thereby improving strength of the joint. The uneven surface portions are obtained in a preliminary forming step of the metal material in a press mold, which is configured with a forming surface for generating the uneven surface portions by mechanical deformation and/or with a device for guiding a laser or electron beam. By this technique, hybrid components are obtained made of one or more elements of metal material between which a shaped component of thermoplastic material is interposed.
