A composite laminate structure includes one or more layers of prepreg and a thermoplastic polyurethane film layer on the surface of the one or more prepregs. A method of making a composite laminate structure including a thermoplastic polyurethane film is also provided.

Disclosed is a composite gypsum board comprising a board core and a concentrated layer, as well as related methods of preparing board and slurries. The board core and the concentrated layer both are formed from water and stucco. The concentrated layer is designed to have higher density and/or nail pull than the core. The concentrated layer is further formed from a polysaccharide that forms a complex with calcium ions, e.g., an alginate compound such as sodium alginate. In some embodiments, the concentrated layer is formed from an enhancing additive to enhance strength therein, while the core is formed without using enhancing additive or less enhancing additive than used in forming the board core.

Disclosed is a heat insulator comprising a substrate comprising of a bulk of silica-based inorganic fiber containing a hydroxyl group; a metallic or ceramic infrared mediator held on at least a part of one surface of the substrate; and a silica cured product holding the infrared mediator on/in the substrate. As the infrared mediator, a metal foil or a ceramic particle may be used. This heat insulator exhibits excellent heat insulating performance in a high temperature range of 600° C. or more, and can be molded into a three-dimensional shape which can be directly mounted to a structure.

Golf balls having covers made of thermoplastic polyurethane compositions are provided. Multi-piece golf balls can be made. Polyurethane primer coatings and polyurethane top-coatings are applied to the thermoplastic polyurethane cover. Different coating methods can be used. Isocyanate-rich and polyol-rich polyurethane coatings can be applied. In one embodiment, the golf ball can be treated with a multi-functional isocyanate prior to applying the coatings. The polyurethane cover composition and surface coatings can further include catalysts, ultraviolet (UV)-light stabilizers, and other additives. Heat is used to cure the coatings. The coating methods have many benefits and the finished balls have good physical properties.

Class-A components (CAC) include a first and second skin layer each having a polymer matrix and a fiber reinforcing material embedded within the polymer matrix, a third layer disposed between the first and second skin layers and including a third polymer matrix and a filler material interspersed within the third polymer matrix, and a Class-A finish coat applied to the second skin layer. The fiber reinforcing materials include a plurality of substantially aligned carbon fibers and a plurality of low strength regions staggered throughout the carbon fibers. The CAC can be integrated with a rigid vehicle frame. The CAC can be a structural component. The CAC can be a door, a roof panel, or a hood. The CAC can include a layer of woven fibers between the Class-A finish coat and the second skin layer and a portion of the woven fibers can be visible through the Class-A surface layer.

A method of fabricating a composite material, the method comprises the steps of a) providing a first layer of a fibre reinforced polymer, preferably a thermoset FRP, b) providing an array of thermoplastic islands across at least a proportion of a major surface of the first layer, c) providing a second layer of a fibre reinforced polymer, preferably a thermoset FRP, d) laying the second layer over at least some of the islands, and e) securing the first and second layers together. There is also disclosed a composite which comprises a first layer of a fibre reinforced polymer and a second layer of a fibre reinforced polymer, between which is an intervening layer comprising an array of thermoplastic islands.

A three-dimensional reinforced membrane is designed to be inflated and used in various structural applications. A dropstitch or double wall fabric may be reinforced with one or more coatings, such as urethane-based coatings, and may also be laminated in accordance with various disclosed embodiments.

A multi-layer protection element for thermal insulation of a battery, a battery with such a protection element and the use of the protection element to filter gases escaping in case of fire and to prevent the escape of flames and/or sparks are proposed. The highly gas-permeable protection element comprises a carrier layer of a fabric and a compressible fibre layer in the form of a sewn non-woven fabric. The protection element is arranged between at least one battery cell and a housing wall of the battery and covers an outlet of the housing wall on the inside. This enables good pressure compensation in the event of fire and/or a short circuit, wherein escaping gases are filtered in particular through the fibre layer and the escape of flames or sparks through the outlet is prevented.

A composite which comprises a first layer of a fibre reinforced polymer and a second layer of a fibre reinforced polymer, between which is an intervening layer comprising an array of thermoplastic islands.

The present invention relates to a molding made of reactive foam, wherein at least one fiber (F) is arranged partially inside the molding, i.e. is surrounded by the reactive foam. The two ends of the respective fiber (F) not surrounded by the reactive foam thus each project from one side of the corresponding molding. The reactive foam is produced by a mold foaming process. 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 according to the invention from reactive foam/the panels according to the invention and also provides for the use thereof as a rotor blade in wind turbines for example.
