Carbon fiber winding machine process parameter adjusting system and tension adjusting method

Abstract

The invention relates to a carbon fiber winding machine process parameter adjusting system modular structure and a tension control method. A winding machine process parameter adjusting system comprises an unwinding module used for releasing fibers, a tension generation module generating enough tension when the tension of the fibers is requested to be high, an adhesive impregnation amount adjustingmodule for precisely controlling the fiber adhesive impregnation amount, a temperature adjusting module for controlling the adhesive temperature and the temperature of the adhesive impregnation fiber, a tension stabilizing module for controlling tension and reducing tension fluctuation in the fiber conduction process and a tension measuring module used for measuring the fiber in real time. Through a modular design method, the function requirement of the system can be finally achieved, the stage-by-stage control strategy is adopted in the tension control method, and through the parameter self-adjusting fuzzy PID algorithm, precise control over the tension is achieved.

Description

technical field [0001] The invention belongs to the technical field of composite material forming, and relates to a modular structure of a process parameter adjustment system of a carbon fiber winding machine and a tension control method. Background technique [0002] Carbon fiber composites have excellent mechanical properties, so they are widely used in high-tech fields such as aerospace. [0003] In the field of aerospace, the forming process of composite components has developed from the more traditional hand lay-up process to more advanced forming processes such as molding, spraying, pultrusion, winding and laying, among which the winding forming process is a kind that has obtained Widely used resin-based composite molding method. The winding molding process is to wind the continuous fiber (or cloth tape, prepreg) impregnated with resin glue on the mandrel according to the pre-arranged trajectory path, and then fix it, demould, and finally obtain a composite product. ...

AI Technical Summary

Problems solved by technology

However, the price of high-end winding machine equipment in my country is still very expensive, and often a winding machine can only process several specific components

When the process requirements change, the winding machine can only be redesigned, which greatly limits the application range of the winding machine, and also makes the processing cost of composite components remain high
