The present invention provides a device for producing a composite material, including: a mat production unit that produces a mat which forms a polymer film having a plurality of fiber layers; a fiber production unit that produces a wide-width fiber which is formed of a plastic resin with a single direction fiber layer; and a composite material production unit to which the mat and the double width fiber are supplied so that the mat and the wide-width fiber are laminated according to a predetermined order of lamination. Also, the present invention provides a composite material produced using the device and a method for producing said composite material.

This specification discloses an article of manufacture. The article of manufacture has at least one structural blank and at least one guide. The structural blank has a plurality of oriented fiber plies in a thermoplastic matrix. The guide has a plurality of random dispersed fibers in a thermoplastic matrix. The guide is affixed to the structural blank by injection molding and over molding the guide onto the structural blank. The article of manufacture can take a number of forms for use in industries such as aircraft, automobiles, motorcycles, bicycles, trains or watercraft.

A threaded shaft for a ball screw comprising: a shaft of fibre-reinforced polymer material; and a helical ridge formed on an outer surface of said shaft, said helical ridge being formed from a fibre-reinforced polymer material comprising a plurality of helical fibres wound around the shaft in the same sense and grouped together to form the ridge. The helical ridge formed from grouped helical fibres all wound with the same sense provides excellent axial load carrying capability as the fibres run continuously from end to end of the shaft and can thus transmit load from end to end. This adds much greater strength than a shaft formed from plastics only. The load carrying capability of the fibre wound helical ridge can indeed approach that of existing metal threads while still being much lighter in weight.

The present invention relates to a multilayer composition comprising a surface layer comprising a thermoplastic polymer A and a substrate layer comprising a polymeric composite material based thermoplastic (meth)acrylic matrix and a fibrous material as reinforcement. The multilayer composition is suitable for mechanical or structured parts or articles with a decorative surface aspect. The present invention concerns also a manufacturing process for multilayer mechanical or structured parts or articles and three-dimensional mechanical or structured parts.

A wind turbine blade component is made by providing a plurality of first pultrusion plates formed of a first pultrusion fiber material, and a plurality of second pultrusion plates formed of a second pultrusion fiber material. The first and second pultrusion plates have a length corresponding to an entire length of a spar cap for a wind turbine blade shell. The first and second pultrusion plates are stacked in a hybrid pattern that contains both first and second pultrusion plates, and the stack is arranged on blade shell material in a mold for the blade shell. The stacked hybrid pattern of first and second pultrusion plates is bonded with the blade shell materials to form an integral blade shell and bonded spar cap component.

A method for connecting insulation panels, each of the panels comprising a cellulosic web having two sides and an outside edge, and comprising layers of cellulosic fibers, the method comprising: arranging a portion of each panel to be adjacent to the other, thereby forming an edge portion where the two webs can be connected; relaxing the fibers of cellulosic material in the edge portion of each insulation panel by applying heat to the edge portion at a temperature of 150? F. to 450? F., thereby forming a relaxed fiber edge portion;
compressing the relaxed fiber edge portion of each insulation panel at a pressure of at least 5 psig, thereby forming a compressed panel portion having a thickness and a density; and
fastening the compressed panel portions together using sewing, riveting, adhesive, tape, interlacing, stamping, ply bonding or stapling thereby forming a fastened area, wherein step (c) can be conducted at the same time or following step (b).

The present invention is a method and apparatus for producing ready to use RFID devices in a convenient and economical manner. The apparatus of the present invention may be collocated with a manufacturer of consumer goods.

In a composite material structure, which is configured as a fiber-reinforced plastic composite material extending in one direction and having a plurality of holes defined at intervals in a row in the one direction and which is subjected to a tensile load and/or a compressive load in the one direction, a peripheral region around the holes comprises a first area obtained by bending composite material, which is reinforced using continuous fibers that have been made even in a longitudinal direction, so that a center line of a width of the composite material weaves between adjacent holes and zigzags in the one direction. A tensile rigidity and/or a compressive rigidity in the one direction of the peripheral region around the holes is lower than a tensile rigidity and/or a compressive rigidity in the one direction of other regions that surround the peripheral region.

A carpet tile having a greige good, an adhesive layer, and a secondary backing material. The greige good has a primary backing component and a plurality of fibers attached to the primary backing component. The adhesive layer has an adhesive composition and a reinforcement material that is at least partially embedded within the adhesive composition. The adhesive layer is applied to a back surface of the primary backing component. The secondary backing material is adhered to the primary backing component by contact with a portion of the adhesive composition that flows through the reinforcement material. The reinforcement material and the secondary backing material are co-laminated onto the adhesive composition.
