Problems solved by technology

If you want to use thermoplastic resins with high melting point and poor fluidity such as PA66, TPU, PEEK and continuous fibers with high linear density such as 2400Tex or woven plain fiber cloth as the base layer, the impregnation effect will be very poor, and there will be obvious The dry yarn or the delamination of the resin layer and the fiber layer can not give full play to the performance advantages of high linear density continuous fiber and fiber cloth, and cannot produce thicker continuous fiber reinforced thermoplastic composite materials.
Therefore, the thickness of the continuous fiber reinforced thermoplastic composite material sheet produced by this kind of molding process is thinner and does not exceed 0.5mm, and it is impossible to use plain fiber cloth as the base layer to produce continuous fiber reinforced thermoplastic composite material

Abstract

The invention belongs to the technical field of composite materials, and relates to a fiber reinforced thermoplastic composite material and a preparation method thereof. A preparation device sequentially comprises a yarn stretching device, an impregnation device, a moulding press, and a heating drying tunnel; and the moulding press includes a first compaction transmission portion and a second compaction transmission portion, the first compaction transmission portion and the second compaction transmission portion are in contact with each other to form a contact surface, and continuous pressureis generated on a passage object entering the contact surface and is transferred to the heating drying tunnel. The fiber reinforced thermoplastic composite material prepared by the preparation deviceand the preparation method can be prepared by selecting high-line-density continuous fibers, is good in impregnation effect, and has no obvious dry yarn or resin delamination phenomenon.

Description

technical field [0001] The invention belongs to the technical field of composite materials, and relates to a fiber-reinforced thermoplastic composite material, a preparation device and a preparation method thereof. Background technique [0002] At present, the fiber thermoplastic composite materials on the market basically use a set of two-roll or three-roll calenders for pressure impregnation. Since only a pair of pressure rollers have a large line contact between the rollers, the pressure impregnation of the resin and the fiber The time is extremely short, so only PP and PE resins with better fluidity and continuous fiber yarns with a linear density not exceeding 1200Tex can be used for arrangement to produce unidirectional continuous fiber thermoplastic composite materials. If you want to use thermoplastic resins with high melting point and poor fluidity such as PA66, TPU, PEEK and continuous fibers with high linear density such as 2400Tex or woven plain fiber cloth as th...
