The present invention is directed to a method of manufacturing a fibre-reinforced polymer composition comprising the steps of providing at least one multifilament strand comprising a plurality of continuous fibre filaments, applying an impregnating agent to said strand to form an impregnated continuous multifilament strand, and embedding the impregnated continuous multifilament strand in a thermoplastic polymer material for providing said fibre reinforced polymer composition, wherein said impregnating agent has a low viscosity at application temperature and is applied by jetting said impregnating agent onto the at least one continuous multifilament strand. The invention is further directed to a device for use in such a method.

The invention relates to a method for manufacturing a part made from composite material, having a body and one or more continuous fibre bundles in its interior, characterised in that it comprises the stages of: a) obtaining a body that includes one or more tubular cavities in its interior that extend between a first end, disposed on the outer surface of the body and which comprises an inlet orifice, and a second end, opposite to the first end; b) introducing resin in the liquid state and a continuous fibre bundle in the interior of at least one tubular cavity through its inlet orifice; and c) curing the resin until it solidifies, adhering to the body and fixing the continuous fibre bundle. The invention also relates to a system for manufacturing a part made from composite material and to the part made from composite material obtained.

According to one implementation, a prepreg lamination apparatus includes first and second rollers, a table, and a feed structure. The first roller sends out a first prepreg tape which is a part of material of an FRP. The second roller sends out a second prepreg tape which is another part of the material of the FRP. The table is for laminating the first and second prepreg tapes directly or indirectly. The feed structure is adapted to feed out the first and second prepreg tapes in a feeding direction by moving the first and second rollers relatively to the table while performing at least one of movement of the first roller relatively to the second roller, and rotation of at least one of the first and second rollers relatively to the table around an axis which is not parallel to each of rotation axes of the first and second rollers.

A process for manufacturing a fibre-plastic composite with a secured fibre orientation, wherein continuous fibres or long fibres are oriented and sheathed with a matrix, characterized by the steps of (a) providing a mold comprising at least one flow channel, (b) introducing the continuous fibres or long fibres into the at least one flow channel, (c) positioning and orienting the continuous fibres or long fibres in the at least one flow channel by way of a pressure gradient in the flow channel, (d) sheathing the continuous fibres or long fibres with a matrix.

Provided is an adhesive composition for organic fiber cords containing (A) synthetic rubber latex having unsaturated diene, (B) gelatin, and (C) an aqueous compound having a (thermal dissociative blocked) isocyanate group and containing no resorcin or formaldehyde, which has the following effects: (1) causing little damage to the environment by using no resorcin or formaldehyde, (2) in a process of coating an organic fiber cord with the adhesive composition for organic fiber cords and drying and heat curing, it is possible to suppress the adhesion of the adhesive composition for organic fiber cords to a roller or the like, thereby achieving good operability, and (3) achieving good adhesion between an organic fiber cord and a coated rubber composition.

Disclosed herein is a process for producing a long glass fibre-reinforced thermoplastic polymer composition, comprising the sequential steps of a) unwinding continuous glass multifilament strand containing at most 2% by mass of a sizing composition; b) applying from 0.5 to 20% by mass of an impregnating agent to form an impregnated continuous multifilament strand; and c) applying a sheath of thermoplastic polymer around the impregnated continuous multifilament strand to form a sheathed continuous multifilament strand, wherein the impregnating agent is non-volatile, has a melting point of at least 20° C. below the melting point of the thermoplastic matrix, has a viscosity of from 2.5 to 100 cS at application temperature, and is compatible with the thermoplastic polymer to be reinforced. This process allows trouble-free handling and unwinding of packages, and results in long glass fibre-reinforced thermoplastic products that can be made into articles having good mechanical properties and high quality surface appearance.

A device for coating a thread with a coating material includes a housing, a die body, and a supply line for the coating material. The housing includes a support and a cover mounted on the support, delimiting a chamber. The die body is installed in the chamber, between the support and the cover. The die body includes a lower part and an upper part, with a calibrated die channel being located between the lower and upper parts. Between the support and the cover are an inlet through passage and an outlet through passage. The inlet and outlet passages and the die channel are aligned, so that a thread is able to be passed longitudinally therethrough. The supply line for the coating material includes a lower outlet end located close to the thread, between the inlet or upstream through passage and the die channel.
