摘要:
Provided is a composite material capable of keeping a good appearance even after heat processed, a method for manufacturing a composite material and a method for manufacturing a molded article. The composite material of the present invention contains a commingled yarn that contains a continuous reinforcing fiber (A) and a continuous thermoplastic resin fiber (B) as fiber components thereof; and a thermoplastic resin fiber (C) that keeps the commingled yarn in place, a thermoplastic resin that composes the thermoplastic resin fiber (C) having a melting point 15°C or more higher than the melting point of a thermoplastic resin that composes the continuous thermoplastic resin fiber (B).

A process for continuous composite coextrusion comprising: (a) forming first a material-laden composition comprising a thermoplastic polymer and at least about 40 volume % of a ceramic or metallic particulate in a manner such that the composition has a substantially cylindrical geometry and thus can be used as a substantially cylindrical feed rod; (b) forming a hole down the symmetrical axis of the feed rod; (c) inserting the start of a continuous spool of ceramic fiber, metal fiber or carbon fiber through the hole in the feed rod; (d) extruding the feed rod and spool simultaneously to form a continuous filament consisting of a green matrix material completely surrounding a dense fiber reinforcement and said filament having an average diameter that is less than the average diameter of the feed rod; and (e) arranging the continuous filament into a desired architecture to provide a green fiber reinforced composite.
摘要:
The present invention relates to a recyclable composite having natural (4) and carbon fibers (6) as a reinforcement material and epoxy resin (8) as a matrix. Preferably, the natural fibers are hemp. Furthermore, the present invention relates to a method for producing such a recyclable composite comprising the steps of preparing the composite, vacuum bagging it and then heating it with a heating cable (12). Finally, the present invention relates to a kit having a frame (10), a heating cable (12) and an apparatus box with a thermostat and heat sensors and which can be used for performing the method according to the invention.
