Building panels with a homogenous decorative surface having a wear layer comprising fibres, binders and wear resistant particles. A building panel including a surface layer and a core, the core including wood fibres, and the surface layer including a substantially homogenous mix of wood fibres, a binder and wear resistant particles, the substantially homogenous mix of wood fibres including natural resins.

A composite material provided in the form of a sheet material includes at least one textile layer as a cover for an airbag. The cover is arranged to form at least one flap with a hinge which includes a hinge region. One side or both sides of the at least one textile layer includes a plastics coating. A melting point of the plastics coating is lower than a melting point of the at least one textile layer. The hinge region is arranged to form at least one single or double fold along the hinge so that the sheet material contacts itself once or twice. In a region of the at least one single or double fold, areas of the plastics coating are arranged to contact each other and, via a prior introduction of heat or a subsequent introduction of heat, are melted onto each other.

An acoustic material comprising one or more acoustic composite layers; and a facing layer, wherein the one or more acoustic composite layers are formed of a nonwoven sound absorption material; wherein the facing layer is permeable; and wherein the facing layer is attached to a top surface of the one or more acoustic composite layers. The facing layer may optionally include metallic components or a metallized outer surface. The acoustic material may optionally include a pressure sensitive adhesive material on an opposing side of the one or more acoustic composite Sayers to enable installation of the acoustic material. The facing layer may include a permeable scrim, a perforated film, or a perforated foil. The facing layer may be metalized on its top exposed surface to provide infrared heat reflection, and a corrosion resistant coating may be applied on top of the metalized layer if required to stabilize the metal coating.

A mold assembly for forming a component exhibiting a sealed interior, including providing first and second mold halves, forming first and second half shells of material within cavities defined within each of the mold halves, and upon mating the mold halves together in a first closed mold configuration. The mold halves are reopened, with at least one of the shells being subsequently reoriented such that the first and second half shells are arrayed in opposing fashion with perimeter extending edges of each half shell arranged in contact with one another. Additional steps include reclosing the mold halves and subsequently forming a second perimeter extending material in contact with the contacting perimeter extending edges in order to bond the half shells together, upon which the mold halves are reopened and a completed component removed.

A joining structure includes a first member, a second member of a material different from that of the first member, and a separation mechanism provided between the first member and the second member and that separates the first member and the second member from each other, wherein a resin is filled into the space between the edge of at least one member among the first member and the second member, and the other member.

The present invention relates to a phosphazene compound containing an ester group having a structure of formula (I). The present invention grafts ester groups to phosphazene compounds and makes terminal grafted hydroxyl and carboxyl groups reacted with polymer matrix, producing an improvement of flame retardancy and a reduction of dielectric constant at the same time when the phosphazene compound is introduced into polymer matrix. Since N and P atoms are directly bonded into the polymer matrix by a reaction rather than addition and combination means in the prior art, there is no reduced mechanical properties of the matrix due to the addition of flame retardants.

The present invention relates to a molding made of expanded bead foam, wherein at least one fiber (F) is partly within the molding, i.e. is surrounded by the expanded bead foam. The two ends of the respective fibers (F) that are not surrounded by the expanded bead foam thus each project from one side of the corresponding molding. The present invention further provides a panel comprising at least one such molding and at least one further layer (S1). The present invention further provides processes for producing the moldings of the invention from expanded bead foam or the panels of the invention and for the use thereof, for example as rotor blade in wind turbines.

A component of a vehicle structure is obtained by a hot forming operation on a hybrid panel having a sheet element of light alloy and a sheet of plastic material. The hybrid panel is hot formed by pressing it against a forming surface of a mould element by a pressurized gas or by a second mould element. Following this operation, the hybrid panel assumes a configuration corresponding to the forming surface, whereas the light alloy sheet element and the plastic material sheet constituting the hybrid panel adhere to each other following softening by heat of the plastic material. Before the hot forming step, a surface of said light alloy sheet element which must contact the plastic material sheet is subjected to a roughening treatment, thereby defining surface asperities between which the plastic material of the plastic material sheet is inserted when it is softened by heat.

Disclosed herein is a technique for further improving the quietness in a vehicle cabin while reducing an increase in the weight of a motor vehicle. A noise reduction member, arranged in a fender inner space defined between a fender panel serving as an exterior panel for a motor vehicle and an inner fender forming a wheelhouse, includes a pair of wall portions which are made of a foamed material and arranged to be spaced apart from each other.

A composite panel structure has opposing outer walls or surfaces and a core comprising a plurality of ribs extending between and connected to the outer walls and defining chambers which are filled with expanding foams, non-expanding foams, gases, or a combination thereof. The outer panel surfaces and internal chamber walls or ribs are made of woven or non-woven fibrous material impregnated with one or more resins. The panel structure may be used for making a variety of products including sports equipment such as sports paddles, surfboards, kite boards, skateboards, wakeboards, as well as construction panels for walls, ceilings or floors, display panels, panels for the vehicle industry, furniture, and other structures requiring high strength to weight properties.
