Abstract:

In order to online monitor damage status of carbon fiber during weaving with upper control system for further providing important references to adjust the loom speed and change the yarn tension and even check stands, a set of applicable evaluation standard and implementation method on damage status of carbon fiber during weaving were put forward. According to the fuzzy control theory, the input and the output of the fuzzy algorithm were analysed and fuzzy rules were also put forward. The realized program can provide evaluation of single yarn damage degree with the Matlab fuzzy logic toolbox. By calling Matlab procedure the evaluation of regional yarn damage is implemented on Labview software platform. The error of damage evaluation results between evaluation algorithm and artificial experience judgment is small. The evaluation standard and implementation method are feasible.

Key words: carbon fiber, weaving, warp damage status, fuzzy algorithm, evaluation standard
