Description

Continuous fiber bicolor one-way belt preparation device

Technical Field

The utility model relates to a two-color one-way zone preparation facilities of continuous fibers.

Background

Continuous Fiber Reinforced Thermoplastic CFRT-Continuous Fiber Reinforced Thermoplastic is a polymer-based composite material developed in the early 70 s of the 20 th century. CFRT is a process of impregnation in which the fibers (glass fibers, carbon fibers, etc.) in the product are maintained in a continuous filament and orderly arrangement. CFRT was originally and at most applied to aerospace, automotive and military industries. Because the excellent performance becomes a competitive hot spot in various countries, the technology is rapidly improved, and the composite material is applied to the lightweight of pipelines and automobiles in recent years.

Over the years of practice, the method of pre-impregnating thermoplastics with increasingly applied continuous fibers is the melt impregnation process: the continuous glass fiber (carbon fiber) bundle is spread into parallel thin layers and impregnated with the extruded resin melt through a compounding die into a continuous sheet containing the thin layers of parallel continuous glass fiber (carbon fiber).

The thermoplastic continuous fiber single-color unidirectional tape is seen in the market, has the advantages of complex process, multiple steps, poor impregnation and uneven thickness, and is only used in the field with low required strength. With the wider application of the market, the thermoplastic continuous fiber unidirectional tape is required to be multi-color, better in impregnation and higher in thickness precision.
