Abstract

The invention provides a carbon fiber fuzzing quantity testing device. The carbon fiber fuzzing quantity testing device is characterized by comprising a tow unwinder, a tow spreader, a fuzziness adsorber and a winder which are sequentially connected in a feeding direction, wherein a drop weight is arranged on the tow unwinder, the tow spreader comprises a plurality of spreading bars, and the fuzziness adsorber comprises sponge and a pressurizing weight disposed on the upper surface of the sponge. The carbon fiber fuzzing quantity testing device has the advantages that through the special arrangement of the spreading bars, carbon fibers can be spread according to a fixed angle, carbon fiber fuzziness exposed during carbon fiber spreading can be collected by the fuzziness adsorber, and accordingly the carbon fiber fuzzing quantity testing device is more accurate when carbon fiber fuzzing quantity is computed.

Description

technical field [0001] The invention relates to the field of fiber technology, in particular to a carbon fiber fuzz collection device and a collection method, a carbon fiber fuzz amount testing device and a measurement method. Background technique [0002] Carbon fiber has attracted attention for its high specific strength, high specific modulus, high temperature resistance, corrosion resistance, good electrical and thermal conductivity and other excellent properties. Advanced resin-based composite materials with carbon fiber as reinforcement have been widely used in aerospace, cultural and sports Various fields such as equipment, civil engineering and construction, automobiles, and energy. However, carbon fiber is a brittle material. During the production process, it is easy to produce some hairs and hair balls due to the breakage of some fibers. When preparing prepregs or composite materials, these hairs and hair balls will cause surface appearance, quality uniformity, etc...
