[0002] Composite materials are materials that have reinforcement added to the base material, and the material properties of the base material and the reinforcement can complement each other to improve the overall material properties. One of the recycling methods of composite materials is to degrade the base material of the composite material into oligomers soluble in the degradation liquid, so that the base material and the reinforcement can be recycled separately.

[0003] The existing practice is to mix the composite material substrate with the degradation liquid and place it in a degradation tank for degradation. When the composite material substrate is degraded by the degradation liquid, the degraded mixture needs to be taken out from the degradation tank, and the composite material reinforcement and the degradation liquid (including the degraded substrate) are separated separately. Then, the composite material reinforcement is separated again, cleaned and dried by various processing devices. In addition, when the next degradation operation is carried out, the degradation liquid needs to be re-injected into the degradation tank and the degradation liquid needs to be heated to the degradation temperature.

[0062] See also Figure 2 , Figure 7 and Fig. 9 The composite material degradation and recovery method of the present invention is applicable to the composite material degradation and recovery system mentioned above, and the composite material degradation and recovery method comprises the following steps:

[0063] Step 91: One of the moving carriers 73 drives one of the inner cylinders 1 to move into one of the degradation cylinders 31, and the filter holes 114 of one of the inner cylinders 1 allow the degradation liquid to enter the chamber 12 to degrade the matrix of the composite material in one of the inner cylinders 1 into the oligomers.

[0064] Step 92: One of the moving carriers 73 drives one of the inner tubes 1 to move from one of the degradation tubes 31 to the separation tube 41, and one of the inner tubes 1 is centrifugally rotated in the separation tube 41, so that the degradation liquid containing the oligomers flows into the separation tube 41 from the filter holes 114 of one of the inner tubes 1.

[0065] When one of the movable carriers 73 drives one of the inner cylinders 1 to move out of one of the degradation cylinders 31 , the degradation liquid containing the oligomers can flow into one of the degradation cylinders 31 through the filter holes 114 of one of the inner cylinders 1 .

[0066] Step 93: The collection box 33 collects the degradation liquid containing the oligomers from one of the degradation cylinders 31 and the separation cylinder 41, and the degradation separator 34 separates the oligomers from the degradation liquid, and the oligomer box 35 collects the oligomers again.

[0067] Step 94 : One of the movable carriers 73 drives one of the inner tubes 1 to move from the separation tube 41 to one of the cleaning tubes 42 , and the corresponding injector 43 injects the cleaning liquid to clean the reinforcing material of the composite material in one of the inner tubes 1 .

[0068] Step 95 : One of the inner cylinders 1 is centrifugally rotated in one of the cleaning cylinders 42 , so that the cleaning liquid containing the degradation liquid flows into one of the cleaning cylinders 42 through the filter holes 114 of one of the inner cylinders 1 .

[0069] Step 96: The central tank 45 collects the cleaning liquid containing the degradation liquid in one of the cleaning cylinders 42, and the cleaning separator 46 separates the degradation liquid from the cleaning liquid, and the degradation liquid tank 47 collects the degradation liquid again.

At this time, the reinforcing material can be collected and recycled.

[0071] The present invention provides the filter hole 114 for the degradation liquid and the cleaning liquid to enter and exit the chamber 12 through the inner cylinder 1 used for containing the composite material, and uses the movable carrier 73 to drive the inner cylinder 1 into the degradation cylinder 31, so that the base material of the composite material is degraded into the oligomers by the degradation liquid, and then the movable carrier 73 drives the inner cylinder 1 containing the reinforcing material of the composite material into the separation cylinder 41, the cleaning cylinder 42 and the drying cylinder 51 for subsequent processing, thereby preventing the reinforcing material from remaining in each device during the process, so as to improve the recovery rate of the reinforcing material of the composite material. In addition, when the composite material in the inner cylinder 1 is degraded by the degradation liquid in the degradation cylinder 31, the movable carrier 73 moves the inner cylinder 1 containing the reinforcement material out of the degradation cylinder 31, and the degradation liquid is still in the degradation cylinder 31. The movable carrier 73 can then place the next inner cylinder 1 containing the composite material into the degradation cylinder 31 to continue the next degradation operation, thereby achieving the effect of continuous composite material degradation operation. Therefore, the purpose of the present invention can be achieved.

A method for recycling composite materials by degradation, characterized in that: The composite material degradation and recovery system according to claim 1 is applicable, wherein the composite material degradation and recovery method comprises the following steps: (A) the movable carrier drives the inner cylinder to move into the degradation cylinder, and the degradation liquid in the degradation cylinder degrades the matrix of the composite material in the inner cylinder into the oligomers; (B) the movable carrier drives the inner cylinder to move from the degradation cylinder to the separation cylinder, and the inner cylinder is centrifugally rotated in the separation cylinder, so that the degradation liquid containing the oligomers flows into the separation cylinder through the filter holes of the inner cylinder; (C) the movable carrier drives the inner cylinder to move from the separation cylinder to the cleaning cylinder, and the injector then injects the cleaning liquid to clean the reinforcing material of the composite material in the inner cylinder; (D) the inner cylinder is centrifugally rotated in the cleaning cylinder, so that the cleaning liquid containing the degradation liquid flows into the cleaning cylinder through the filter holes of the inner cylinder; and (E) The movable carrier drives the inner cylinder to move from the cleaning cylinder to the drying cylinder, and the dryer then dries the reinforcing material of the composite material in the inner cylinder.

16. The method for recycling composite materials according to claim 15, characterized in that: The degradation device also includes a collecting box connected to the degradation cylinder and the separation cylinder, a degradation separator connected to the collecting box, and an oligomer box connected to the degradation separator. The degradation and recovery method of the composite material also includes a step (B′) after step (B). In step (B′), the collecting box collects the degradation liquid containing the oligomers, and the degradation separator separates the oligomers from the degradation liquid, and the oligomer box collects the oligomers again.

17. The method for recycling composite materials according to claim 15, characterized in that: The separation device also includes a concentration box connected to the cleaning cylinder, a cleaning separator connected to the concentration box, and a degradation liquid tank connected to the cleaning separator. The degradation and recovery method of the composite material also includes a step (D′) after step (D). In step (D′), the concentration box collects the cleaning liquid containing the degradation liquid, and the cleaning separator separates the degradation liquid from the cleaning liquid, and the degradation liquid tank collects the degradation liquid again.
