Carbon fiber multi-workstation tension control machinery automatic sample preparation method

Abstract

The invention relates to a carbon fiber multi-workstation tension control machinery automatic sample preparation method. The method includes: step 1, putting 5 spindles of fiber on a spindle of a sample preparation machine, enabling the fiber to pass a resin tank at a running speed of 5m / min through 5 roller guide wheels which are tensioned at set tension of 100-500 g, extruding surplus resin on the fiber through an extrusion guide wheel, and winding a plurality of fibers on a diamond sample preparation frame taking stainless steel as a main body at the same time; putting the whole frame in an oven with an inner cavity of 1m in size, and drying at set temperature of 150 DEG C for 2h; after drying is finished, cutting down a testing sample piece from the frame; step 2, adopting hot pressing equipment, and curing to prepare samples in batches at pressure of 1 ton and at temperature of 150 DEG C. The method is balanced in sample preparation, influence of artificial sample preparation is eliminated, and tension and speed amount samples are formed under certain conditions, so that data reliability is improved.

Description

technical field [0001] The invention relates to the technical field of carbon fiber equipment, in particular to a carbon fiber multi-station tension control mechanical automatic sample preparation method. Background technique [0002] The original carbon fiber test sample preparation method adopts two methods: manual dipping and shaking. Manual dipping is to manually wind the fibers on a square frame, and soak the frame wrapped with fibers in a resin solution. During the winding process of sample preparation, each person feels different when stretching the fiber, and the tightness of the fiber varies greatly. Glue shaking is to manually dip a section of fiber in the resin solution, then manually straighten the fiber, shake it repeatedly, shake off the excess resin remaining on the fiber, and then manually wind it on a square frame. The winding process is still different. People control the strength of straightening fibers differently. But no matter which one, it is necess...

AI Technical Summary

Problems solved by technology

But no matter which one, it is necessary to manually stretch the fiber and mix and soak the fiber and resin. The common defect is that the tension control of the fiber depends entirely on manual experience. The test samples made by different people are quite different. Experienced people can only manufacture test samples based on experience, and there is no process data control that can be used to check and verify
