In particular, the central control device compares the acquired resistance of the reinforcing device during the process of leading in the special fibers with the preset resistance, and adjusts the pushing force of the splicing device, wherein when the acquired resistance of the central control device is smaller than or equal to the first preset resistance, the resistance of the reinforcing device to be overcome when leading in the special fibers is not very large, the current adjacent ceramic plates are loosely spliced, and are easily broken when being impacted by bullets, so that the central control device increases the pushing force of the splicing device, and when the acquired resistance of the central control device is larger than or equal to the second preset resistance, the reinforcing device needs to overcome very large resistance to guide the special fibers between the adjacent ceramic plates, so that the splicing is too tight, and the bearing capacity on the impact force can be reduced, and therefore, the central control device reduces the pushing force of the splicing device.
In particular, the central control device compares the obtained pushing force of the splicing device with a preset pushing force, and adjusts the quantity of the special fibers led in by the reinforcing device, wherein when the pushing force obtained by the central control device is smaller than or equal to a first preset pushing force, the pushing force is smaller, the interval between the ceramic plates is larger, in order to enable the combination between the ceramic plates to be more stable, the central control device judges to increase the quantity of the fibers led in by the reinforcing device, when the pushing force obtained by the central control device is larger than or equal to a second preset pushing force, the pushing force is larger, the interval between the ceramic plates is smaller, more special fibers do not need to be led in, and in order to save cost and avoid the influence of excessive special fibers on the performance of a ceramic combination layer, the central control device judges to reduce the quantity of the fibers led in by the reinforcing device.
In particular, the central control device compares the thickness increase rate of the bulletproof fiber layer acquired in the pressing process with the preset thickness increase rate, and the pressing force of the pressing device is adjusted once, wherein when the thickness increase rate acquired by the central control device is smaller than or equal to the first preset increase rate, the thickness increase of the bulletproof fiber layer is slow, the two-dimensional prepregs are combined tightly, the buffering capacity of the bulletproof fiber layer on the bullet impact force can be reduced, the bulletproof fiber layer is thinner, the bulletproof performance of the composite bulletproof ceramic can be influenced, the pressing force of the pressing device is reduced by the central control device, and when the thickness increase bulletproof rate acquired by the central control device is larger than or equal to the second preset increase rate, the two-dimensional prepregs are combined loosely, so that the fiber bulletproof layer is too thick, and the portability of the composite ceramic is reduced, and the pressing force of the pressing device is increased by the central control device.
In particular, the thickness of the bulletproof fiber layer should be kept in a certain proportion with the thickness of the ceramic composite layer, which would otherwise affect the bulletproof performance of the composite bulletproof ceramic, so that the central control device obtains a balance degree through the thickness of the bulletproof fiber layer and the thickness of the ceramic composite layer, when the balance degree obtained by the central control device is smaller than or equal to a first preset balance degree, the thickness of the bulletproof fiber layer is smaller than that of the ceramic composite layer, so that the central control device judges to reduce the pressing force of the pressing device, the number of layers of the two-dimensional prepreg is increased to increase the thickness of the bulletproof fiber layer, and when the balance degree obtained by the central control device is larger than or equal to a second preset balance degree, the thickness of the bulletproof fiber layer is larger than that of the ceramic composite layer, so that the central control device judges to increase the pressing force of the pressing device, and reduces the number of layers of the two-dimensional prepreg to reduce the thickness of the bulletproof fiber layer.
Particularly, after the bulletproof fiber layer and the ceramic composite layer are adhered to form a pre-assembly, a sound transmission test is carried out, the obtained sound transmission speed of the pre-assembly is compared with a preset sound transmission speed by the central control device, the glue amount between the ceramic composite layer and the bulletproof fiber layer is adjusted, wherein when the sound transmission speed obtained by the central control device is smaller than or equal to a first preset sound transmission speed, the glue amount between the ceramic composite layer and the bulletproof fiber layer is smaller, more air exists between the ceramic composite layer and the bulletproof fiber layer, the compactness is poor, so that the central control device judges that the glue amount is increased, and when the sound transmission speed obtained by the central control device is larger than the first preset sound transmission speed and smaller than the second preset sound transmission speed, the sound transmission speed is smaller than the sound transmission speed when the air exists, the glue amount between the central control device is too much, the redundant sound transmission blocked by glue is influenced, the bulletproof performance is affected, and the central control device judges that the glue amount is reduced, and adhesion is carried out again.
In particular, the ceramic combination layer and the bulletproof fiber layer are adhered to form a pre-combined part through fiber micropore riveting to form a combined part, in order to determine the number of micropore riveting structures, the central control device obtains the laminating difficulty through the thickness of the ceramic combination layer and the thickness of the bulletproof fiber layer, and compares the obtained laminating difficulty with the preset laminating difficulty, the number of micropore riveting structures is respectively turned over on the surface of the bulletproof fiber layer, wherein the larger the laminating difficulty is, the more easily separation of the ceramic combination layer and the bulletproof fiber layer is caused, and therefore, the larger the laminating difficulty is, the larger the number of micropore riveting structures selected by the central control device is.
In particular, the central control device performs sound transmission detection on the assembly formed by combining the ceramic composite layer and the bulletproof fiber layer, when the sound transmission speed of the assembly obtained by the central control device is smaller than or equal to a first preset sound transmission speed standard value, the compactness of the assembly is far lower than a preset standard at this time, because the microporous riveting structure is used for reinforcing the assembly, the compactness is far smaller than the preset standard because the ceramic composite layer has problems, the compactness of the combination between ceramic sheets does not meet the preset standard, therefore, the central control device judges to increase the driving force of the pushing device so that the compactness of the assembly formed next time meets the preset standard, and when the sound transmission speed obtained by the central control device is larger than the first preset sound transmission speed standard value and smaller than the second preset sound transmission speed standard value, the compactness of the assembly is relatively close to the preset standard at this time, the central control device judges to increase the number of microporous riveting structures used for reinforcing at this time so that the compactness of the formed assembly meets the preset standard, and when the sound transmission speed obtained by the central control device is greater than or equal to the second preset standard, the sound transmission speed obtained by the central control device meets the preset standard, and the performance of the assembly is respectively met the preset sound transmission speed standard and the vacuum-modified ceramic composite layer and the bulletproof fiber layer is formed by the composite ceramic.
