摘要： According to the present invention, there is provided a pipe forming apparatus for forming a pipe at an installation site. The apparatus includes a former upon which material is wound, and a mold for receiving the former bearing the wound material. An applicator is provided for applying curable liquid within the mold. Advantageously, the pipe is formed at site to provide for efficient formation of a pipeline. A transported ISO container providing the material and curable liquid to the site can produce 800 metres of pipeline section, compared with 60 metres in the prior art, representing a significant increase in efficiency.

摘要： Provided is a method for manufacturing a fiber reinforced resin molded article capable of distributing the pressure without concentration on the vicinity of the resin inlet and so preventing the deformation of a preform, and such a manufacturing device thereof. The method lowers a lower core as a moving core in a lower mold (first mold) (away from a preform) to let resin flow toward the lower mold (first mold). This distributes the pressure concentrated in the vicinity of the resin inlet and prevents deformation of the preform.

摘要： A method and device for mixing plastic from liquid components in a mixer (8) and conveying it through a line (10) into a mould (12), in particular for vacuum infusion, characterised in that the components are each pumped by means of a pump (24) from their own respective component container (22) into a mixer (8) and are mixed therein, that these volume flows are controlled by a controller (26) in such a manner that they supply the components to the mixer (8) in a specific ratio, that the pressure loss in the line (10), between a pressure sensor in one of the component supply lines (32) leading to the mixer (8) and the mould (12), is determined, and that the pressure is measured by the pressure sensor and supplied to a controller (26) which, taking into consideration the determined pressure loss, controls the volume flows such that the pumps (24) supply the components to the mixer (8) at a pressure that is greater than the ambient pressure or than another specific pressure that should not be exceeded in the mould (12) by at most the pressure loss.

摘要： A process of forming the fiber preform includes providing a substrate, applying a first layer of a fiber bundle to the substrate in a predetermined pattern having a principal orientation, stitching the first layer of the fiber bundle to the substrate using a thread, building up subsequent layers of the fiber bundle from the first layer, and stitching each of the subsequent layers to a preceding layer using the thread. A process of forming a unitary reinforced composite material includes the fiber preform. The process of forming a unitary reinforced composite component includes placing the fiber preform a mold platen, heating the perform to promote fusion of the thermoplastic fibers therein, cooling the perform until solidified with contours of the component, and removing the vehicle component from the mold platen.
