A housing for an electronic device is disclosed. The housing comprises a first component and a second component separated from the first component by a gap. The housing also includes a first molded element disposed at least partially within the gap and defining at least a portion of an interlock feature, and a second molded element disposed at least partially within the gap and mechanically engaging the interlock feature. The first component, the second component, and the second molded element form a portion of an exterior surface of the housing. A method of forming the housing is also disclosed.

The present disclosure relates to a plank with anti-slip function and a method preparing the same; it belongs to the technical field of plank manufacturing. The plank with anti-slip function includes a support body and an anti-slip body clamped on the support body; the anti-slip body has a clamping member; the support body is provided with a plurality of clamping grooves that cooperate with the clamping member; the clamping groove is provided with at least one limiting part that restricts the clamping member from escaping from the clamping groove; the support body is made of thermoplastic material, and the anti-slip body is made of elastomer material. In the present disclosure, by replacing the material of the support body with thermoplastic polyolefin, the cost of the support body is significantly reduced, and the strength is improved; the present disclosure will also provide a matching structure between the support body and the anti-slip body to make the anti-slip body firmly clamped on the support body, so that the present disclosure simultaneously exerts the advantages of the thermoplastic support body and the elastic anti-slip body, thereby the plank has the advantages of high compressive strength and good surface contact.

A method for preparing a multi-material component including providing a fiber reinforced component, the fiber reinforced component having one or more working layers of a fiber reinforced composite material, wherein each of the one or more working layers includes one or more fiber reinforced composite material laminae. The method includes attaching the fiber reinforced component to a multi-material transition component, wherein the multi-material transition component includes a metallic component and a transition laminate includes a transition material, wherein the transition laminate includes one or more partially embedded transition laminae each having a first embedded end that is embedded in the metallic component. Also provided are multi-material transition components and multi-material components provided by the method.

A method for attaching a first window component to a second window component comprising the steps of: engraving a surface of the first window component with at least one first type cavity, and attaching the second window component to the first window component by introducing an anchor portion of the second window component into the least one first type cavity.

One aspect is an insert molded torsion bar hinge including a cylindrical metal torsion bar with a main bar body, a portion of which extends along a torsion bar axis, a first contoured bar end and a second contoured bar end on opposite ends of the main bar body. A first hinged element of molded plastic and with a first knuckle, is molded directly over and encompasses the first contoured bar end such that the first contoured bar end is fixed within and not rotatable relative to the first hinged element. The first knuckle is molded directly over and encompassing a portion of the main bar body. A second hinged element of molded plastic and with a second knuckle is molded directly over and encompasses the second contoured bar end such that the second contoured bar end is fixed within and not rotatable relative to the second hinged element. The second knuckle is molded directly over and encompassing a portion of the main bar body. The first and second hinged elements rotate and produce a torsional spring torque.

A fiber-reinforced resin substrate is described in which a plurality of resins having differing properties are strongly composited, wherein the fiber-reinforced resin substrate is obtained by impregnating a thermoplastic resin (A) and a thermoplastic resin (B) into continuous reinforcement fibers, wherein a thermoplastic resin (A) layer, which comprises the thermoplastic resin (A) and is exposed at one surface, and a thermoplastic resin (B) layer, which comprises the thermoplastic resin (B) and is exposed at the other surface, form a boundary region, where at least some of the continuous reinforcement fibers exist in a manner spanning across the boundary region and both the thermoplastic resin (A) and the thermoplastic resin (B) are crystalline resins having a melting point of not less than 200 C.

Disclosed are reinforced structures. The structures are comprised of reinforced elements that have continuous fibers embedded in a matrix material. The reinforced elements are combined in a matrix material to form a desired shape of reinforced structure.
