A unitized composite aircraft wing (14) includes upper and lower composite laminate wing skins (22, 24) that have differing stiffnesses and are bonded to a composite grid structure (34). The grid structure (34) includes grid spars (40) extending in a spanwise direction, and cross beams (42) extending in a chord-wise direction of the wing (14). The grid spars (40) include caps bonded to the upper and lower wing skins (22, 24).

An accessory unit includes a front flap and a rear cover. The rear cover includes a recessed portion that defines a chamber and a frame that extends about an opening of the chamber. The chamber is configured to receive a consumer electronic device, and the frame is configured to hold the consumer electronic device therein. For example, the frame may define a multi-sided cross-section with an inner edge thereof configured to engage a chamfered edge of the consumer electronic device. The front flap may include segments formed from panels with folding regions therebetween, which allow the front flap to fold. Further, an end region of the front flap hingedly couples the front flap to the rear cover, such that the front flap may be moved between open and closed configurations.

Composite structures and methods for mitigating edge glow resulting from lightning strikes on composite structures, such as aerospace structures, containing carbon fiber reinforced plastic components. One or more thin layers of conductive coating material is applied over a cut edge or drop off of the carbon fiber reinforced plastic components to reduce inter-ply voltage potential between composite layers of the carbon fiber reinforced plastic component. The conductive coating (308) material is made of a conductive doping material (310) dispersed in a carrier medium.

Exemplary methods for manufacturing a wire and resultant wires are disclosed herein. The method includes extruding a receptor cross-linkable polymer that is substantially free of curing agent about a conductive core and extruding a donor polymer in association with a curing agent. The method includes disposing the donor polymer about the receptor polymer and conductive core to create a multi-layer wire pre-product. The method also includes heat curing a multi-layer wire pre-product to form a wire.

The invention relates to the use of an encoded and detectable polymer component, wherein encodable and detectable particles are completely embedded or embedded by segments in the polymer material of said polymer component, for marking an article against product piracy, wherein the article consists of a polymer material, a polymer-textile composite, a polymer-metal composite or a polymer-textile-metal composite, and wherein the encoded and detectable polymer component is furthermore integrated in the article. The marked article is in particular a hose. The encoded and detectable polymer component is, for example, a retaining sleeve (1) for a hose clamp, comprising a retaining ring (2) having a retaining bridge (3) and retaining collar (4).

This disclosure relates to a composition for a composite sheet including core-shell type filler particles comprising magnetic particles covered with thermally conductive ceramic compound, and a curable organic binder, a composite sheet comprising the core-shell type filler particles, and a method for preparing the composite sheet. According to the composition for a composite sheet, excellent thermal conductivity and electromagnetic wave absorption performance may be achieved without degradation of dielectric strength, and low hardness of the final composite sheet may be achieved with the same filler contents.

An object is to provide an impact-absorbing structure superior in impact-absorbing capacity. An impact-absorbing structure includes a pair of flat, plate-like face plates (19) arranged to oppose each other with a predetermined distance therebetween; a core member (17) arranged between the face plates and fixed to the face plates; and a composite-material tube arranged between the face plates (7), at the core member side, the impact-absorbing member extending in one direction and fracturing progressively due to an impact compression force acting in the one direction. The composite-material tube is fixed to the face plates at one portion constituting a bonded region and is allowed to move relative to the face plates at a remaining portion constituting a non-bonded region.
