Abstract

The invention discloses an impregnated fiber bundle sample making device and method. The device comprises a rear creel, a moving platform, a braking device, a wheel strain, a glue pressing device, a glue extruding device, an impregnating tank and a fiber rack. The device is simple in structure, a test can be done through the four faces of at most four creels simultaneously, and the sample making period is effectively shortened. When a fiber sample is tested, not only can the impregnated fiber glue extruding tension be controlled, but also the sample making number can be increased; in addition,the fiber rack in the device is a four-face device, therefore, sample making work of multiple groups of fiber samples can be completed, the fiber rack can be clamped into a curing oven for rotating and curing, and the ununiformity of glue liquid on the fiber bundle surfaces is avoided.

Description

technical field [0001] The invention belongs to the technical field of winding and forming manufacturing of resin-based composite materials, and in particular relates to a sample preparation device and method for impregnated fiber tow. Background technique [0002] At present, with the development of industry, carbon fiber materials have replaced the status of traditional steel and iron to a certain extent by virtue of their light weight and superior electrical conductivity, and are widely used in aerospace and civil fields. The performance of composite materials depends to a large extent on the combination of carbon fiber and resin, and in the process of fiber testing, making impregnated fiber tow for mechanical performance testing is the most commonly used method. In the process of dipping fiber sample preparation, the biggest problem is how to make the fiber bundles be stressed as uniformly as possible, and how to prevent adjacent fiber bundles from sticking during curing...
