Abstract

The invention provides a continuous carbon fiber thermoplastic prepreg preparation system. The prepreg preparation system comprises a creel, a fiber spreading device, a coating device, a hot pressingdevice and a winding device; a carbon fiber bundle is arranged on the creel, the carbon fiber bundle is drawn out of the creel and then enters the coating device after being uniformly spread by the fiber spreading device, after the coating device is used for spraying resin with the carbon fiber bundle, heating and rolling of the hot pressing device are carried out to form a prepreg tape with complete impregnation, and finally the prepreg tape is rolled through the winding device. The continuous carbon fiber thermoplastic prepreg preparation system has the beneficial effects that the size of awhole set of equipment is small, the whole set of equipment is less than 5m, and the occupied space is small; the equipment with modularization design, and the fiber spreading and the preimpregnatingcan be carried out separately; a fiber tape with uniform width and thickness can be obtained; a hot pressing module can control the shrinkage in the heating process of a bonding body, so that the prepreg tape with uniform thickness can be obtained.

Description

technical field [0001] The invention relates to the field of carbon fiber preparation, in particular to a continuous carbon fiber thermoplastic prepreg preparation system. Background technique [0002] Continuous carbon fiber reinforced composites have excellent properties such as high specific strength and large specific modulus, so they have been widely used. At present, continuous carbon fiber reinforced thermosetting composite materials are widely used. Thermosetting prepreg tapes are prone to crosslinking when the temperature is too high. The storage period at room temperature is within one month, and the storage environment requirements are high; thermosetting composite materials are difficult to recycle and do not decompose. It is not conducive to environmental protection; and thermoplastic composite materials have the advantages of excellent fatigue performance, short molding cycle, heat repair and easy recycling, so they are widely used in the fields of sports and l...
