Problems solved by technology

However, a curing agent is mixed in the resin used for fiber bundle prepreg, so that when the temperature is too high or the exposure time to high temperature is increased, there is a problem that hardening starts

example 1

[0095] Carbon fibers were installed in the supply member 101; the fibers were unwound; and the fibers were passed through rollers in the fiber supply section (where the rollers were heated to 80° C.) to heat and expand the carbon fibers.

[0096] In order to manufacture a tow prepreg which is commonly used and has a resin content of 30%, the width of the fibers passing through the expander roll is controlled such that α is 20°.

[0097] The fiber passes through the gap between the first roll (metal) and the second roll (rubber) heated to 80°C. In this case, the gap between the two coating rollers was set to 0.2 mm so that the resin was sufficiently coated between the carbon fiber bundles. Next, the gap between the second roll and the third roll heated to 80°C was set to 0.135 mm, and in this case, the gap between the second roll and the third roll was set in consideration of the influence of resin flow. The gap was adjusted so that the width of the fiber passing through the g...

Abstract

An apparatus for manufacturing tow prepreg includes: a spreading roller which adjusts an incident angle of supplied fiber; and two or more coating rollers including a first roller and a second rollerwhich rotate while having a gap between the first roller and the second roller, in which the fiber supplied from the spreading roller passes through the gap between the first roller and the second roller to be coated with resin. The incident angle of the fiber supplied for immersing the resin is adjusted to adjust tension applied to the fiber supplied to a coating roller, thereby adjusting the content of resin. The invention further provides a method for manufacturing the tow prepreg.

Description

technical field [0001] The present disclosure relates to apparatus and methods of manufacturing tow prepregs, and more particularly, to apparatus and methods of manufacturing tow prepregs useful as pressure vessel materials for fuel cell vehicles. Background technique [0002] A pressure vessel for storing high-pressure gas requires a material that is substantially strong and has high-pressure resistance properties, and in particular, in order to improve fuel efficiency and performance of a fuel cell vehicle, structural portability is essential. The application of lightweight and strong carbon fiber composites is one of the most effective alternatives to pressure vessels formed from metal. [0003] The pressure vessel formed from the composite material is manufactured by a filament winding method. The filament winding method can easily manufacture a structure having a circular shape or a bend through integral molding, and intensively reinforces fibers in a load transfer dir...
