The inventive fiber manufacturing process is particularly adapted for demanding applications such as sports racquets. Because of the improved strength to weight ratio of components formed using the inventive method, a wide range of flexibility is achieved, allowing use of the inventive process to manufacture, for example, a fiber reinforced (for example, graphite) modular sports racquet, optionally provided with user-selectable weights and/or handle replacements. The inventive fiber (for example, graphite fiber) racquet frame is filled with a plastic foam and is formed using, for example, microencapsulation technology to time, generate and apply the pressure and gives the same or greater strength for a given size compared to conventional racquets. Advantageously, an outer tubular member may be used to form the racquet frame, with an inner tubular member extending around the head of the racquet frame.

The present invention concerns a method of producing an insulation product comprising a board of porous insulation material wrapped in a gas-impermeable foil, said method comprising the steps of providing a succession of porous insulation material boards on a first conveyor apparatus and feeding the boards on a second conveyor apparatus; providing wrapping foil and wrapping said foil to form a tube around the boards on said second conveyor apparatus, flushing the boards with an insulating gas, and sealing the wrapping foil at the ends of each board transverse to the direction of travel of the second conveyor apparatus.

The present invention relates to a booster seat comprising a seat shell with a lower face for supporting the seat shell and an upper face, on which a seat base and lateral seat cushion regions and backrest regions that delimit the seat base laterally and rearwards are provided. The lower face of the seat shell has a stacking contour which is designed to provide a stacking capability on the upper face of the seat shell. The invention also relates to a booster seat comprising a strap system that has four eyelets, wherein one retaining strap is allocated to a pair of eyelets. Two eyelets are arranged in the front outer region of each lateral seat cushion region, while two eyelets are arranged in the rear outer region of each lateral seat cushion region or in the lateral outer region of the back region. The invention further relates to a method for producing a booster seat of this type.

The invention relates to a shut-off flap (26) for a motor vehicle shut-off device, notably for a device for shutting off an air inlet in the front face of a motor vehicle, comprising a flap body (28), the flap body (28) being at least partially made of a fibre reinforced composite material, notably one that uses continuous reinforcing fibres (42, 44). The invention also relates to a motor vehicle shut-off device comprising such a flap and to methods of manufacturing this flap and this shut-off device for a motor vehicle.

a method for manufacturing a part made of composite material includes the steps of placing, in a mold, a fibrous preform including reinforcing fibers and being resin-impregnated, positioning a prefabricated element in the mold in contact with the fibrous preform at a predefined location of the fibrous preform, the prefabricated element having a predefined form and being produced in composite material comprising partially polymerized resin, compressing the assembly formed by the fibrous preform and the prefabricated element in the mold, heating the assembly formed by the fibrous preform and the prefabricated element in the mold to polymerize the resin and thus binding the prefabricated element with the fibrous preform in order to form the part made of composite material.

A long fiber sheet molding compound and a manufacturing method thereof are illustrated. The long fiber sheet molding compound has a first resin layer, a second resin layer and a hybrid layer being disposed between the first resin layer and the second resin layer. The hybrid layer has a fiber mesh structure being formed by a plurality of fiber silks which are discontinuous and twisted to each other to have a non-directional distribution. The manufacturing method of the long fiber sheet molding compound at least has following steps: a material providing step, an adhesion step and a lamination step. Thus, compared to the prior art, the long fiber sheet molding compound of the present disclosure can efficiency reduce a fiber content, a thickness and a weight, and an anti-slicing strength, an anti-bending strength and an anti-bending modulus can be uniform in any direction.

The inventive fiber manufacturing process is particularly adapted for demanding applications such as sports racquets, including tennis racquets, badminton racquets and other sports applications. Because of the improved strength to weight ratio of components formed using the inventive method, a wide range of flexibility is achieved, allowing use of the inventive process to manufacture, for example, a fiber reinforced (for example, graphite) modular sports racquet, optionally provided with user-selectable weights and/or handle replacements. From the standpoint of the player, this allows a racquet frame featuring self customization. From the standpoint of a retailer, the benefit provided is reduction of inventory. The inventive fiber, for example graphite fiber) racquet frame is filled with a plastic foam and is formed using, for example, microencapsulation technology to time, generate and apply the pressure used to form the graphite composite material of which the racquet is comprised. Advantageously, inner and outer tubular members may be used to form the racquet frame, with the inner tubular member extending around the head of the racquet frame. This compares to the standard industry technique of air injection. The racquet is thus not hollow like conventional graphite racquets, and the walls therefore can be made thinner than those of existing graphite racquets still being of the same strength or being stronger, which gives the racquet exceptional performance. In addition, the overall dimensions of, for example the cross-section, of the racquet can also be reduced while still maintaining performance characteristics.

A method is disclosed for making an article with an additive manufacturing machine that includes a build platform (14) and an additive material dispensing nozzle (18) for controlled application of the additive material with respect to a location of the build platform. The method includes attaching a first part (24a) to the build platform. The first part includes a first mating surface that includes a protruding portion (34) and a recessed portion (32). A digital model of a second part that includes a second mating surface comprising recessed and protruding portions (39, 38) complementary to the first mating surface is inputted to the additive manufacturing machine. The nozzle dispenses and hardens an incremental quantity of a polymer material to the first mating surface according to the digital model, and successively-dispensed incremental quantities of polymer material are applied and hardened according to the digital model to produce the article including first and second parts.
