Embodiment 1

[0019] Illustrate the embodiment of the present invention in conjunction with accompanying drawing, under certain tension effect (tension size is controlled by tension device 2), continuous carbon fiber 1 passes through guide roller 3 at a certain speed and impregnates through PEK-C resin solution 4 of certain concentration Glue, so that it is soaked with a certain amount of resin matrix, and then pass through the scraping roller 5 to remove excess glue, and then pass through the drying tunnel 6, and the solvent is removed by drying to obtain a carbon fiber prepreg tape 8, and the solvent is carried out after passing through the exhaust duct 7. Recycling.

[0020] The carbon fiber prepreg tape 8 enters the preheating device 9 for preheating, then utilizes the heat provided by the heating device 10 to melt the matrix resin (the temperature is measured by an infrared thermometer 11), and then winds longitudinally on the surface of the tubular mandrel 12. Under the action of tens...

Embodiment 2

[0023] The present embodiment is described in conjunction with the accompanying drawings. Under a certain tension (the tension is controlled by the tension device 2), the continuous carbon fiber 1 passes through the guide roller 3 at a certain speed and then impregnates it with a certain concentration of PES-C resin solution 4. Soak it with a certain amount of resin matrix, then pass through the scraping roller 5 to remove excess glue, then pass through the drying tunnel 6, and dry to remove the solvent to obtain a carbon fiber prepreg tape 8, and the solvent is recovered after passing through the exhaust duct 7 deal with.

[0024] The carbon fiber prepreg tape 8 enters the preheating device 9 for preheating, then utilizes the heat provided by the heating device 10 to melt the matrix resin (the temperature is measured by an infrared thermometer 11), and then wraps it in a hoop direction on the surface of the annular mandrel 12. Under the action of tension, the pores between th...

Embodiment 3

[0027] In conjunction with the accompanying drawings to illustrate this embodiment, the continuous glass fiber 1 is impregnated with a certain concentration of PEK-C resin solution 4 after passing through the guide roller 3 at a certain speed under a certain tension (the tension is controlled by the tension device 2). , so that it is soaked with a certain amount of resin matrix, and then pass through the scraping roller 5 to remove excess glue, and then pass through the drying tunnel 6, and then dry to remove the solvent to obtain a glass fiber prepreg tape 8, and the solvent passes through the exhaust duct 7 For recycling.

[0028] The glass fiber prepreg tape 8 enters the preheating device 9 for preheating, and then utilizes the heat provided by the heating device 10 to melt the matrix resin (the temperature is measured by an infrared thermometer 11), and then longitudinally and annularly carry out the process on the surface of the tubular mandrel 12. Alternately wrap around...

Abstract

The invention discloses a method for winding a cardo-containing polyaryletherketone or polyarylethersuifone resin matrix composite, which comprises the following steps that: N-methylpyrrolidone, chloroform, N,N-dimethyl acetamide, morpholine or methylene dichloride and other solvents are used to prepare a PEK-E or PES-C resin solution at a certain concentration; continuous fibers are impregnated with gum and the solvent is removed to prepare a prepreg; during winding, the prepreg is first pre-heated to a certain temperature before reaching a mandrel, and then wound on the surface of the mandrel in a longitudinal direction, circumferential direction or alternately in the two directions under the action of a certain tensile force; and at the same time, the prepreg is further heated to promote the rise matrix to be fused quickly to adhere winding layers and finally consolidates and cools to form a compact winding structure. The method of the invention can manufacture high-performance thermoplastic composite winding members which are light in weight, high in strength and high temperature-resistance, and can meet the needs of petrochemical, sports, building and aerospace fields and other fields.

Description

technical field [0001] The invention relates to a method for preparing continuous fiber-reinforced polyaryletherketone (PEK-C) or polyarylethersulfone (PES-C) resin-based composite materials containing phenolphthalein side groups through a winding process, in particular to thermoplastic resin-based composite materials winding molding method. It belongs to the field of advanced composite material manufacturing technology. Background technique [0002] Filament winding molding is a common process method for manufacturing resin-based composite products, and it is one of the low-cost methods for manufacturing composite structures. This method can configure reinforcing materials according to product performance requirements. It has high structural efficiency, high product strength, continuous and mechanized production, and is mainly suitable for forming large rotating components. widely used. [0003] Thermoplastic resins and their composite materials have developed rapidly in...
