The invention provides for it before, to form the mold comprising a plurality in the direction of production consecutive mold sections each having the cross-section of the plastic profile corresponding shaping passage, said mold sections in order to achieve a desired course of the plastic profile are displaced so that the longitudinal directions of the shaping passages on the longitudinal center axis of the plastic profile and are tangential to the central longitudinal axis of the plastic profile extending.


BMW: Method for producing a fiber-reinforced plastic component

Bayerische Motoren Werke AG has filed a World Intellectual Property Organization (WIPO) patent application for a method for producing a fiber-reinforced plastic component. This invention was developed by Jan Pfrang and Roman Sternagel.

According to the abstract released by the WIPO: The invention relates to a method for producing a fiber-reinforced plastic component, having the following steps: arranging an insert element into at least one fiber layer, the reinforcing fibers of the fiber layer being locally displaced by the insert element; aligning the at least one fiber layer in an open cavity of a tool; closing the tool cavity; and infiltrating the fiber layer located in the cavity with a matrix material.


Japan U Pica Co Ltd: Urethane (meth)acrylate compound

Japan U Pica Co Ltd has filed a WIPO patent application for a urethane (meth)acrylate compound. This invention was developed by Tetsuji Moroiwa, Nozomi Ishine, and Hiroshi Hayashi.

According to the abstract released by the World Intellectual Property Organization: The present invention provides a heat-curable resin which enables the production of a carbon-fiber-reinforced plastic having good workability and excellent mechanical properties by hand lay up (HUP) molding, resin transfer molding (RTM) or vacuum assisted resin transfer molding (VaRTM). The urethane (meth)acrylate (A) compound according to the present invention is a urethane (meth)acrylate produced by reacting a compound having at least two isocyanate groups with a monoalcohol compound containing an ethylenically unsaturated group or by reacting a compound having at least two isocyanate groups with a monoalcohol compound containing an ethylenically unsaturated group and an alcohol compound having at least two hydroxy groups, said urethane (meth)acrylate (A) compound being characterized by having an isocyanate group and an ethylenically unsaturated group.


NDSU Research Foundation: Self-Healing Nanofibers, Composites and Methods for Manufacturing

NDSU Research Foundation has filed a WIPO patent application for self-healing nanofibers, composites and methods for manufacturing. This invention was developed by Xiangfa Wu, Arifur Rahman, Zhengping Zhou and Youhao Zhao.

According to the abstract released by the World Intellectual Property Organization: The present invention is a new type of hybrid high-strength carbon-fiber/epoxy composites reinforced with ultrathin toughening and self-healing core-shell fibers at interfaces by means of wetted lay-up, followed by vacuum-assisted resin transfer molding (VARTM) technique. The core-shell fibers loaded with liquid healing agent (a liquid monomer at room temperature) are produced by co- electrospinning, in which a plastic polymer solution (dissolved in an organic solvent) is used as the exterior jet and the monomer solution (dissolved in the same organic solvent) is used as the interior jet. Also described is a fiber manufacturing device utilizing a novel dual-wire emulsion-electrospinning method capable of producing ultrathin continuous core-shell and hollow fibers in commercial volumes.


Anhui Jincen Composites Co Ltd: Method for smoothing inner wall of GRP

The State Intellectual Property Office of China has received Anhui Jincen Composites Co Ltd's patent application for method for smoothing inner wall of GRP. Li Xirui, Ai Qian and Yang Juncheng developed the invention.

According to the abstract: The invention relates to the field of GRP (glass reinforced plastic), in particular to a method for smoothing the inner wall of the GRP. The method comprises the following steps: a) polishing burrs or bulged parts on the inner wall of the GRP by using a polishing tool; and b) brushing or spraying a resin layer onto the polished inner wall of the GRP. Observable burrs and bulged parts are polished manually, and the resin layer is brushed or sprayed on the polished inner wall of the GRP, so that the inner wall surface damaged during polishing is repaired, and reduction of the aging resistance of the inner wall of the GRP is prevented. Furthermore, brushing and spraying of the resin layer can fill concave pits in the inner wall of the GRP, then only the bulged parts on the inner wall are required to be polished so as to achieve smoothing of the inner wall of the GRP, the polishing quantity is reduced greatly, dust harm to human bodies is reduced, and the work efficiency is improved simultaneously.
