A body part for a road vehicle comprising an outer portion configured to be arranged on the outer side of a road vehicle and defining a first side of the roof panel; an inner portion configured to be arranged, with respect to the outer portion, towards a passenger compartment of the road vehicle and defining a second side of the roof panel; wherein the outer portion comprises one or more first composite material layers, each comprising a reinforcement texture; wherein the outermost layer of said one or more first composite material layers, i.e. the one visible, in use, from the outside of the road vehicle, comprises a plurality of metal filaments woven into the reinforcement texture.

Assemblies of stacked layers of materials are described. The assemblies include functional and structural layers. Functional layers include binderless ceramic materials on woven or non-woven substrates of natural, synthetic, or metallic materials. The layers of functional and structural materials may be configured to transport moisture or heat from an inner surface to an outer surface that is exposed to an ambient environment.

One or more aspects of the present disclosure provide components for an article of manufacture, having a film with an optical element that imparts a structural color to the component. The present disclosure also provide methods for making components with the films and optical element, and articles of manufacture including the component.

One or more aspects of the present disclosure are directed to components having an optical element that imparts structural color to the component or article. The present disclosure is also directed to articles of manufacture including the component having an optical element, and methods for making components and articles having an optical element that imparts structural color.

Systems and methods of forming fiber reinforced polymer (FRP) composites with electrostatic dissipative properties are described herein. The FRP composite is bonded to a surface and integrates a grounding system to dissipate electro-static energy, thus eliminating the potential risk of explosion. The system can be used for structures that require reinforcement and that are susceptible to electro-static explosions.

A method for manufacturing a flame-resistant textile material for protective clothing is characterized in that at least one textile layer is subjected to a treatment step wherein at least one fibre component is at least partially detached from the textile layer such that air chambers (5) are formed.

The tape incudes a water vapor-permeable air and water barrier article and a pressure sensitive adhesive layer. The air and water barrier article includes a fibrous layer having first and second major surfaces and a polymeric layer on a first major surface of the fibrous layer that penetrates into the fibrous layer but leaves at least some fibers exposed on the second major surface. The pressure sensitive adhesive layer is on the polymeric layer of the air and water barrier article. The tape can retain greater than 50 percent by weight of mortar applied according to the Vertical Mortar Receptivity Evaluation. The article includes a substrate, the tape, and a composite layer comprising at least one of gypsum, lime, or cement. The composite layer is at least one of dried or cured on the second major surface of the fibrous layer. Methods of making the article are also described.

Embodiments are directed to systems and methods for creating a tubular composite structure. In one embodiment, a device comprises multiple layers of cured composite fabric bonded together to form a tubular composite structure, wherein alternating groups of the multiple layers comprise on-axis fabric and off-axis fabric. The tubular composite structure may form a spar for an aerodynamic component. The composite fabric may comprise one or more of carbon, fiberglass, or other composite materials, or a combination of materials. One or more stacks of the fabric wrap completely around the tubular composite structure, and other stacks of fabric may not wrap completely around the tubular composite structure.

A multilayered bullet resistant member, including a three-layered structure formed of a metal-ceramic crack arrest reflecting layer, a fiber-elastomer composite energy absorbing layer and a two-dimensional fabric blunt trauma protective layer sequentially overlapped with each other. The integration of performances of all the components guarantees high strength, hardness and good impact toughness of the bullet resistant member.

One or more aspects of the present disclosure provide optical element transfer structures that include an optical element releasably coupled with a transfer medium and methods of making and using the optical element transfer structures. The optical element transfer structures can be used to dispose an optical element onto an article, whereby the optical element imparts a structural color to the article.
