AI Technical Summary

Problems solved by technology

Therefore, this molding technology not only requires high technical requirements, but also has complicated equipment structure.
The investment is huge, the process is difficult, the manufacturing cost is high, and its prepreg must be stored under low temperature refrigeration conditions, and the storage period is only a few months; at the same time, it must be cured under high temperature conditions when used
Therefore, prepregs cannot be produced in large quantities, nor can they be stored for a long time, and the production and storage costs are expensive, and the curing conditions and costs are also high. They can only be limited to the application of high value-added products such as aerospace and high-end sports equipment.

Embodiment Construction

[0013] like figure 1 As shown, this equipment first combs and positions the carbon fiber tow cluster v, and v first passes through the bridge roller 1, the telescopic fixed-width reed 10, the guiding and positioning reed 11-1, the slitting twisting roller 12, and the traction roller 13-1. Positioning, in order to further ensure the positioning of v when entering the thermocompression forming device, v passes through the bridge roller 2, the guide positioning reed 11-2, the bridge roller 3, the slitting twist rod 14 and then enters the thermocompression forming device, when v wears When the positioning reeds 11-1 and 11-2 are passed through the guide, it can comb the V into a semi-overlapped positioning state with a slope; the slitting twisting roller and the slitting twisting rod respectively play the role of stacking and arranging the v "pin" shape Or the effect of superimposed arrangement along the oblique direction. The guide reeds of the guide positioning reed are arrange...

Abstract

An apparatus for preparing the carbon fibre sheet with back net by hot pressing is composed of the locating-carding unit for carbon fibre tows, back net feeder divided into two parts, hot pressing unit with two hot-pressing rollers, finished product winder, and several delivery rollers. Its advantages are simple structure, and low cost of product.

Description

Technical field: [0001] The invention relates to a carbon fiber forming technology, in particular to special equipment for forming a carbon fiber sheet. technical background: [0002] Carbon fiber is currently one of the most excellent performance and most widely used reinforcement materials in advanced composite materials. How to make carbon fiber in a state of uniform distribution, high orientation and straight arrangement, and become a new material that is convenient to use, permanent storage and low cost, is still to maximize the use and play of its strength and modulus characteristics, and realize the low cost of composite materials the key to. The technology closest to the present invention is carbon fiber prepreg molding technology. This technology is to pre-impregnate the high-temperature cured latent resin matrix (or clamped on the adhesive film) carbon fiber tows that are highly oriented and arranged in parallel on the release paper tray, and then heated to the p...
