2Make ultrasonic transmitter (4) begin length feed to the right by numerical control servo mechanism (5) from the front side left end of silicon rubber container (3), feed speed is 15mm/min～25mm/min, ultrasonic transmitter (4) is launched ultrasonic near the whole ULTRASONIC ABSORPTION liquid (6) the interior vertical vertical guide of silicon rubber container (3) from the top down, again along the horizontal direction of silicon rubber container (3) feeding 5mm～15mm backward, begin length feed left from right-hand member then, feed speed is 15mm/min～25mm/min, ultrasonic transmitter (4) is launched near the whole ULTRASONIC ABSORPTION liquid (6) the ultrasonic next vertically vertical guide to silicon rubber container (3) from the top down, so repeats until inswept whole ULTRASONIC ABSORPTION liquid (6); Repeat above-mentioned scanning process then and rise to 130 ℃, then the ultrasonic sound intensity is reduced to 800W/cm until ULTRASONIC ABSORPTION liquid (6) temperature
2, be incubated scanning 2h down at 130 ℃;
Then, the ultrasonic sound intensity is risen to 10000W/cm
2, scanning 0.5h makes ULTRASONIC ABSORPTION liquid (6) temperature rise to 200 ℃, then the ultrasonic sound intensity is reduced to 1200W/cm
2, be incubated scanning 3h down at 200 ℃;
At last, the ultrasonic sound intensity is reduced to 80W/cm
2, scanning 4h closes ultrasonic transmitter (4) then, makes ULTRASONIC ABSORPTION liquid (6) temperature reduce to 0 ℃～40 ℃, and in this temperature, pressure change procedure, polymer base carbon fiber composite material blank (7) solidified forming is corresponding product; Pressure in the whole process mesohigh water pot (1) that ultrasonic transmitter (4) heats ULTRASONIC ABSORPTION liquid (6) is regulated accordingly.
5. the water under high pressure can shaping method of polymer base carbon fiber composite material according to claim 4 is characterized in that: the pressure in the whole process mesohigh water pot (1) that ultrasonic transmitter (4) heats ULTRASONIC ABSORPTION liquid (6) is regulated in 10MPa～20MPa.
6. according to the water under high pressure can shaping method of the described polymer base carbon fiber composite material of one of claim 3 to 5, it is characterized in that: described ULTRASONIC ABSORPTION liquid (6) is the pure matrix resin of glycerine or polymer base carbon fiber composite material.
