Determination of fluff amount of carbon fiber tow
1 Scope
This document specifies the test principle, test conditions, instruments and equipment, samples, test procedures and test data processing of carbon fiber tow fuzziness
and test reports, etc.
This document is applicable to polyacrylonitrile-based carbon fiber tows of 1k~50k, and carbon fibers of other specifications can also be used as a reference.

GB/T 8813 Determination of compression properties of rigid foamed plastics
GB/T 26749 Determination of tensile properties of carbon fiber dipped yarn
GB/T 40724 Terminology of carbon fiber and its composite materials
3 Terms and Definitions
The terms and definitions defined in GB/T 40724 apply to this document.
4 Test Principle
The carbon fiber tow is stretched and thinned by the guide rod at a certain speed under the mechanical traction with the length measuring device, and then passed through a pair of
A fuzz collecting material with normal load, which produces moderate friction on the unwound tow and collects the fuzz in the tow. Weighing fuzz collection
The amount of fluff is obtained from the change in mass of the material before and after the fluff is collected.
5 Test conditions
Before the test, place the sample in a laboratory environment with a temperature of (23±2)°C and a relative humidity of (50±10)% for not less than 24h. exist
Tested in the same environment.
6 Instruments and equipment
6.1 Fuzz tester
As shown in Figure 1, the fuzz tester is mainly composed of the following parts.
a) Unwinding device. with a tension adjustment device, which can provide unwinding tension for the tow unwinding process. Rubber and other materials can be used to provide unwinding
tension. The unwinding tension ranges from 100g to 800g, and the recommended values are shown in Table 1 (the breaking strain is determined according to GB/T 26749).
