A body panel for repairing damaged vehicle bodies including a layer assembly. The body panel makes use of a fibrous sheet that includes fiber glass, carbon fiber, or Kevlar that would be easily painted and installed to replace damaged vehicle bodies. The body panel makes great usage for repairing damaged body panels as it is strong and durable as it does not dent, it is lightweight, it is inexpensive, and it importantly does not rust.

A roof construction for a motor vehicle, including a displaceable roof element which is displaceable between a retracted out-of-use position and an extended use position, wherein the roof element in its extended use position is in a spaced-apart position relative to a body of the vehicle. Arranged on the roof element is a folding bellows which, when the roof element is in the use position, assumes an opened state and bridges a gap between the roof element and the body, and which, when the roof element is in the out-of-use position, assumes a compressed state collapsed in folds. The folding bellows has a layer structure with at least two different layers.

A sole includes a bottom layer and a carbon fiber layer. The bottom layer has at least two engaging portions. The carbon fiber layer is penetrated by at least two fitting holes. The at least two engaging portions are engaged with the at least two fitting holes, respectively. The diameter of the at least two fitting holes, which is close to the bottom layer, is less than the diameter of the at least two fitting holes closed to a upside surface of the carbon fiber layer. The at least two engaging portions undergo an injection process so as to be coupled to the at least two fitting holes, respectively, thereby reducing greatly the chance of injury which might otherwise happen to users as a result of separation of the bottom layer and the carbon fiber layer of the sole while the users are running quickly.

A magnetic PCB generated by simultaneously spin-spraying a ferrite ion solution and an oxidant solution on a substrate plate while the substrate plate is rotated at a speed 40 rpm to about 300 rpm and heated at 40° C. to 300° C.

An kinetic object protection system for protecting a space in a building or vehicle comprising a protective barrier including one or more sheets of a laminated material having a plurality of layers of lightweight, flexible, ballistic resistant material such as woven sheets, nets, or mesh which are secured together using a glue, heat weld, or stitching. The system may include an automated control system operably configured to cause a change in state of the barrier from a retracted state to a protective deployed state, which may include a sensing system operably configured to detect a threatening event, wherein the sensing system upon sensing the threatening event triggers the barrier to transition from the retracted state to the deployed protective state such that in the protective state, the barriers are adapted to be resistant to penetration by the kinetic objects such as vehicles.

A molded article of a carbon fiber composite material includes at least carbon fibers and a resin composition. The molded article of a carbon fiber composite material is characterized in that the surface roughness Ra thereof is 0.01-2 μm and in that the tensile shear adhesive strength (F0) thereof when a metal has been adhered to the surface thereof via an adhesive layer that contains an epoxy compound and is 0.1-3 mm thick is 10-40 MPa.

The invention relates to composite sleeves for producing a cured in place pipe, to materials and methods for producing the composite sleeve, to methods for repairing a native pipe with the composite sleeve, and to improved cured in place pipes. The composite sleeve has multiple layers including a core layer of a curable one-part resin composition. The curable one-part resin composition is a solid material at 25° C. Preferably the resin composition is pliable at 25° C. so that it can be flexed during manufacturing and/or during installation in a native pipe.

A ballistic panel and a ballistic panel assembly that absorb and stops high velocity projectiles is provided. The ballistic panel includes a first layer assembly with a first plurality of weave mesh layers, a second layer assembly with a second plurality of weave mesh layers, and a third solid layer sandwiched between the first layer assembly and the second layer assembly. The ballistic panel assembly can include a releasably attachable GPS tracking chip, an alert signaling device, and/or an outer electromagnetic shield.

A composite skinned panel is disclosed which uses, in some embodiments, a combination of cementitious, insulative and ablative core materials to provide a building panel which can effectively meet a variety of different commercial, residential and marine fire codes. For example, one such fire test is an A60 fire rating (International Marine Organization (IMO) A60 Class A Bulkhead), which establishes that the panel provide 60 minutes of protection from a front side temperature of 1750° F. without raising the internal temperature more than 250° F.

Disclosed is a ceramic matrix component having a fibrous core and a ceramic matrix composite shell surrounding at least a portion of the fibrous core. The ceramic matrix composite shell comprises a fibrous preform. The fibrous core has a greater porosity than the fibrous preform. A method of making the ceramic matrix component is also disclosed.
