Abstract

The invention belongs to the material technical field, and relates to a wide width continuous fiber reinforced thermoplastic plastic coiled material and a preparation method and implementation device thereof. The device from left to right sequentially comprises an uncoiling part (6), a heating and melting component (7), a rolled part (8) and a rolling unit (9), wherein the uncoiling part (6) is provided with a welding device (54). According to the device provided by the invention, the uncoiling part is improved, and the welding device (54) is added; and the product quality and production efficiency in the processing process can be greatly improved. The prepared continuous fiber reinforced thermoplastic plastic coiled material has the advantages of wide width, wide thickness range, higher strength, low elongation, low recovery rate, good continuous tension and long service life, and can be applied in many fields of automotive, transportation and building, etc.

Description

technical field [0001] The invention belongs to the field of material technology, and relates to a wide-width continuous fiber-reinforced thermoplastic coil, a preparation method and a realization device thereof. Background technique [0002] At present, due to the limitations of equipment and processing technology, most of the continuous fiber reinforced thermoplastic coils are narrow in width, but the products produced in many application fields have wide widths and require wider continuous fiber reinforced thermoplastic coils. For example, the inner liner of the container requires the coil to have a long size and width, and the coil for building plate reinforcement also requires a large length and width. The new type of van also requires the coil to be continuous and wide of. However, when narrow-width continuous fiber-reinforced thermoplastic coils are prepared for wide-width products, not only the processing technology is complicated, but also the final mechanical prop...
