The invention relates to a method for continuous production of a composite material profile by injection-pultrusion from at least one reinforcing fabric and at least one thermoplastic polymer having high fluidity, said method being characterized in that: i) said fabric is continuously pulled with a pulling speed of at least 0.4 m.min.sup.−1 in the course of said process; ii) the impregnation stage is performed by injection of a polymeric composition having high fluidity through the fabric; iii) the profile is then shaped with a specific thermal profile.

The invention also relates to a profile obtained according to the method of the invention and a composite article comprising such a profile the curvature whereof may be modified in its curvature by bending and/or its profile by rotational molding.

A method of providing a fibre-reinforced composite material, the method comprising: dispersing particles of a first polymeric composition comprising a first thermoplastic in a liquid comprising water, thereby forming a dispersion; coating, at least in part, a first set of reinforcement fibres with the dispersion; redistributing the particles of the first polymeric composition comprised in the coating; and melting at least some of the redistributed particles of the first polymeric composition comprised in the coating, thereby providing the composite material.

The invention relates to a method for coating a textile hose (4) with a thermoplastic sealing material (5), in particular polyurethane-based, in a coating device (2). The textile hose (4) has a longitudinal direction and a circumferential direction and is manufactured continuously in the longitudinal direction and in the circumferential direction, in particular formed from a tubular knit hose; the textile hose (4) is fed to the coating device (2) and is continuously drawn onto a mandrel (6) extending in the longitudinal direction and approximately in the vertical direction (8) and is continuously transported further over this mandrel (6), the mandrel (6) being supported and oriented according to the position by at least one support means (10) provided outside the textile hose (4). The thermoplastic sealing material (5) is provided in a heated flowable state and is fed continuously to an entire outer circumference (38) of the textile hose (4) which is continuously transported over the mandrel (6) in such a way that some of the thermoplastic sealing material (5) can penetrate into the textile hose (4) and/or can adhere to the outer circumference (38) of the textile hose (4) and forms a closed superficial coating, and the textile hose (4) coated in this way is then continuously drawn off from the mandrel (6).

The present invention relates to a process for the treatment of technical textiles based on thermoplastic fibers and comprising a coating, such as, in particular, airbags, using the principle of centrifugal decanting to separate the fiber residues and the coating material. The invention also relates to a process for the manufacture of a thermoplastic composition, in particular for molding, obtained by use of the fiber residues as obtained and optionally of reinforcing fillers. The distinguishing feature of this invention is based on the preparation of the fabric devoid of coating, thus resulting in formulations with elevated mechanical performances.
