Embodiment 1

[0040] 1. Arrange the continuous carbon fiber (that is, Mitsubishi Rayon Grafil TR50S carbon fiber) on the arrangement machine.

[0041] 2. Then immerse the continuous carbon fiber in the molar ratio of resorcinol: 4-phenylacetylene phenylhydroquinone: 4-4'difluorobenzophenone is 0.4:0.6:1, and the viscosity is 76mpa*s 1 In the glue solution, set the parameters of the prepreg arranging machine to the traction tension of 5N and the traction speed of 10m / min to start routing.

[0042] 3. Remove the carbon fiber / polymer prepreg collected by the collection roller and place it in a cool place to dry. The resin content of the obtained prepreg is 32.1 wt%, the impregnation is good, and the surface is smooth and even. see figure 1 Photo.

[0043] 4. Cut the prepared carbon fiber / polymer prepreg tape into a suitable size, and put it into a mold for hot pressing. The hot-pressing parameters are as follows: first raise the temperature to 240°C, melt for 15 minutes, then raise the tem...

Embodiment 2

[0045] The glue solution in the embodiment 1 step 2 is changed to the polymerization molar ratio and is hydroquinone: 4-phenylacetylene phenylhydroquinone: 4-4' difluorobenzophenone is 0.8: 0.2: 1, and the viscosity is For the formula 2 glue of 66mpa*s, the remaining processes in steps 1, 2, and 3 are consistent with embodiment 1. The resin content of gained prepreg is 28.2wt%, impregnation is good, and the surface is smooth and level (see figure 2 Photo). Step 4 is to put the prepared carbon fiber / polymer prepreg tape into a mold for thermocompression molding. The hot-pressing parameters are as follows: first raise the temperature to 240°C, melt for 15 minutes, pressurize to 0.6 MPa, raise the temperature to 370°C, keep constant pressure and temperature for 1 hour, and take out the sample after natural cooling.

Embodiment 3

[0047] All the other are consistent with embodiment 1 except following processing conditions. The glue solution in the embodiment 1 step 2 is changed to a polymerization molar ratio of resorcinol: 4-phenylacetylene phenylhydroquinone: 4-4' difluorobenzophenone is 0.1: 0.9: 1, and the viscosity is Formula 1 glue of 90mpa*s. The resin content of the obtained prepreg is 36.5 wt%, the impregnation is good, and the surface is smooth and even. The prepared carbon fiber / polymer prepreg tape is put into a mold for thermocompression molding. The hot-pressing parameters are as follows: first raise the temperature to 230°C, melt for 15 minutes, pressurize to 0.6 MPa, raise the temperature to 350°C, keep constant pressure and temperature for 1 hour, and take out the sample after natural cooling.

Abstract

The invention belongs to the field of polymer materials, and relates to a polyether-ether-ketone polymer carbon fiber composite material containing a phenylacetylene side group and a preparation method thereof. The composite material consists of a polyether-ether-ketone polymer containing the phenylacetylene side group and a high-strength continuous carbon fiber, wherein the composite material comprises the following components in percentage by mass: 20-80% of the carbon fiber and the balance of the polyether-ether-ketone polymer. The preparation method comprises the following steps: firstly dissolving resorcinol or hydroquinone, 4-phenylacetylene phenylated hydroquinone and 4-4' difluorobenzophenone into a chloroform configuration adhesive solution, then preparing a carbon fiber/polymer prepreg tape by using a prepreg distributor, and finally performing compression molding. The composite material prepared by using the method disclosed by the invention has excellent mechanical performance, thermal performance and corrosion resistance, and combines the toughness of a thermoplastic resin based composite material and the advantages of a thermosetting resin based composite material so as to meet the requirements of the fields of supersonic aircrafts, military industries and high technologies; and moreover, the composite material is simple in preparation method, a production process is easy to operate, and production equipment is easy to achieve.

Description

technical field [0001] The invention belongs to the technical field of high-performance polymers, and specifically relates to two polyether ether ketone polymer carbon fiber composite materials containing phenylacetylene side groups and a preparation method thereof. Background technique [0002] Materials are the forerunner and material basis of technological progress, and the development of almost all new technologies is inseparable from the application of new materials. Therefore, all countries in the world attach great importance to the research and development of new materials. High-performance resin-based composites have the characteristics of high specific strength and high specific modulus, making them typical representatives of new lightweight high-strength materials. [0003] Thermosetting resin-based composites and resin matrices have been greatly developed and applied well, but their applications are limited due to their poor toughness and low damage tolerance of...
