| titleOfInvention | A kind of continuous carbon fiber reinforced polyarylene ether nitrile composite material prepreg tape and preparation method thereof |
| abstract | The invention discloses a continuous carbon fiber reinforced polyarylene ether nitrile composite material prepreg tape and a preparation method thereof, belonging to the technical field of polymer composite materials. The novel polyarylene ether nitrile resin provided by the invention can be dissolved in alcohol and ketone solvents to prepare a resin solution, and a carbon fiber composite material unidirectional prepreg tape can be prepared by a solution prepreg process, which solves the technical problem that the resin cannot fully infiltrate the carbon fiber by the melting method. At the same time, the solvent has a high boiling point and is slightly soluble or insoluble in water, which overcomes the problems of easy moisture absorption and volatility of traditional polar solvents, and uses a coagulation bath to recover most of the organic solvents, shortening the drying time, and compacting by hot pressing rollers. The prepreg tape is obtained, which greatly improves the production efficiency and process stability, and reduces the production cost. The composite material prepared by the composite material prepreg tape provided by the invention has excellent mechanical properties and thermal properties, and has low manufacturing cost, which is favorable for popularization and application in the civil high-tech field. |
