The invention provides a preparation process of a
composite material laminated plate formed by directionally arranging carbon naon-tubes. The preparation process is characterized by comprising the following steps: (1) mixing
acetone with carbon nano-tubes in a
mass ratio of 100: 1, stirring for 5 min by using a high-speed
cutting stirrer at the stirring rate of 20000 r / min, and
drying for standby use; ..., (5)
hot pressing and forming a prepreg with the upper surface and lower surface respectively laid with a
copper film
electrode in a
composite material hot vulcanizing instrument, first heating to 40 to 60 DEG C, respectively introducing high-frequency pulse alternating-current power to the
copper film electrodes at the upper end and lower end of the prepreg, wherein the
electrification time is 5 to 10 minutes, removing the power after the
electrification, then heating to a curing temperature of
epoxy resin, thermally insulating for 2h, naturally cooling, and demolding to prepare the
composite material laminated plate of carbon
fiber /
epoxy resin filling the carbon nano-tubes. According to the preparation process, the carbon naon-tubes are directionally arranged along the thickness direction (direction Z) of the laminated plate by utilizing a high-frequency
pulse electric field, so that the preparation process is simple to operate, and the produced composite material has excellent performance.
