Continuous carbon fiber reinforced PEKK prepreg production process and equipment

Abstract

The invention discloses a continuous carbon fiber reinforced PEKK prepreg production process and equipment, relates to the technical field of continuous carbon fiber reinforced PEKK prepreg production, and is mainly used for solving the problem that industrial production of continuous carbon fiber reinforced PEKK prepregs cannot be realized in China at present. The continuous carbon fiber reinforced PEKK prepreg production process comprises the following steps: 1, performing unwinding and leveling; 2, performing carding; 3, spreading the yarns and removing a sizing agent; 4, performing gluing; 5, performing primary gum dipping; 6, performing secondary gum dipping; 7, performing cooling; 8, performing online detection; and 9, performing winding. The equipment structurally comprises a creel, a guide roller set, a grate, a high-temperature drying oven, gluing molds, an extrusion dipping roller set, a dipping device, a cooling platform, an online detector, a traction roller set and a winding device. According to the continuous carbon fiber reinforced PEKK prepreg production process and equipment provided by the invention, the industrial production of the continuous carbon fiber reinforced PEKK prepreg can be completed by utilizing the process and the equipment.

Description

technical field [0001] The invention relates to the technical field of continuous carbon fiber reinforced PEKK prepreg production technology, in particular to a continuous carbon fiber reinforced PEKK prepreg production process and equipment. Background technique [0002] At present, with regard to the continuous carbon fiber reinforced PEKK prepreg preparation technology, aerospace research institutions represented by NASA and some manufacturers represented by Japan's Toray are relatively leading in the world. [0003] Since continuous carbon fiber reinforced thermoplastic composite materials are mostly used in aerospace, satellite, military and other fields at this stage, especially carbon fiber reinforced PEKK composite materials are strictly prohibited for export in Japan, the United States, Europe and other countries. Its related technologies and equipment are highly confidential and are prohibited from being exported to China. As for carbon fiber reinforced PEKK prepr...
