Especially, well accuse device will acquire the reinforcing apparatus is at the resistance that leading-in special fiber in-process received with predetermine the resistance and compare, it is right splicing apparatus's motive force is adjusted, wherein, when the resistance that well accuse device acquireed when the first predetermined resistance that predetermines, it is not very big to explain this moment reinforcing apparatus at the resistance that leading-in special fiber will overcome, the pine of concatenation between the current adjacent ceramic wafer, it is very easy broken when receiving the bullet impact, consequently, well accuse device increases splicing apparatus's motive force, when the resistance that well accuse device acquireed is more than or equal to the second predetermined resistance, it indicates this moment that reinforcing apparatus need overcome very big resistance just can lead-in special fiber between the adjacent ceramic wafer, the concatenation is too close, can reduce the bearing capacity to the impulsive force, consequently, well accuse device reduces splicing apparatus's motive force through subtracting.
Especially, well accuse device will acquire splicing apparatus's driving force compares with predetermineeing the driving force, and is right the leading-in special fiber volume of reinforcing apparatus adjusts, wherein, when the driving force less than or equal to first predetermined driving force that well accuse device acquireed, explains that the driving force is less this moment, and the interval between the ceramic wafer is great, and in order to make the combination between the ceramic wafer more firm, well accuse device judges the increase the leading-in fiber volume of reinforcing apparatus, when the driving force more than or equal to second predetermined driving force that well accuse device acquireed, explains that the driving force is great this moment, and the interval between the ceramic wafer is less, need not lead-in more special fiber, avoids excessive special fiber to influence the performance of ceramic combined layer simultaneously for the cost saving, and well accuse device judges to reduce the leading-in fiber volume of reinforcing apparatus.
In particular, the central control device compares the thickness growth rate of the bulletproof fiber layer obtained in the pressing process with a preset thickness growth rate, once adjusts the pressing force of the pressing device, wherein, when the thickness growth rate acquired by the central control device is less than or equal to a first preset growth rate, the thickness growth of the bulletproof fiber layer is relatively slow, the two-dimensional prepreg cloths are combined very tightly, the buffering capacity of the bulletproof fiber layer on the impact force of bullets can be reduced, and the bulletproof fiber layer is thinner, which can affect the bulletproof performance of the composite bulletproof ceramic, so that the central control device reduces the pressing force of the pressing device, when the thickness increase rate obtained by the central control device is more than or equal to a second preset increase rate, the combination between the two-dimensional prepreg cloth is loose, the fiber bulletproof layer is too thick, thereby reducing the portability of the composite bulletproof ceramic and consequently increasing the pressing force of the pressing device by the central control device.
In particular, the thickness of the ballistic fiber layers should be maintained in a certain ratio to the thickness of the ceramic composite layers, which would otherwise affect the ballistic performance of the composite ballistic ceramic, therefore, the central control device obtains a balance degree through the thickness of the bulletproof fiber layer and the thickness of the ceramic combination layer, when the balance degree obtained by the central control device is less than or equal to the first preset balance degree, the thickness of the bulletproof fiber layer is smaller than that of the ceramic combination layer, therefore, the central control device judges that the pressing force of the pressing device is reduced, the layer number of the two-dimensional prepreg cloth is increased to increase the thickness of the bulletproof fiber layer, when the balance degree obtained by the central control device is more than or equal to the second preset balance degree, the thickness of the bulletproof fiber layer is larger than that of the ceramic combination layer, therefore, the central control device judges that the pressing force of the pressing device is increased, and the number of layers of the two-dimensional prepreg cloth is reduced so as to reduce the thickness of the bulletproof fiber layer.
Particularly, the bulletproof fiber layer and the ceramic combination layer are adhered to form a pre-assembly for sound transmission test, the central control device compares the obtained sound transmission speed of the pre-assembly with a preset sound transmission speed, and adjusts the glue amount between the ceramic combination layer and the bulletproof fiber layer, wherein when the sound transmission speed obtained by the central control device is less than or equal to the first preset sound transmission speed, the glue amount between the ceramic combination layer and the bulletproof fiber layer is less, more air exists between the ceramic combination layer and the bulletproof fiber layer, and the compactness is poor, so the central control device judges that the glue amount is increased, when the sound transmission speed obtained by the central control device is greater than the first preset sound transmission speed and less than the second preset sound transmission speed, although the sound transmission speed is higher than that when air exists, the sound transmission speed is lower, the situation that the glue amount between the ceramic combination layer and the bulletproof fiber layer is too much, the sound transmission blocked by the redundant glue is influenced by the bulletproof performance, therefore, the central control device judges that the glue amount is reduced and performs adhesion again.
Particularly, a pre-assembly formed by adhering the ceramic combination layer and the bulletproof fiber layer is riveted through fiber micropores to form an assembly, in order to determine the number of the micropore riveting structures, the central control device obtains the attaching difficulty through the thickness of the ceramic combination layer and the thickness of the bulletproof fiber layer, compares the obtained attaching difficulty with the preset attaching difficulty, and selects the number of the micropore riveting structures on the surface of the bulletproof fiber layer, wherein the larger the attaching difficulty is, the easier the separation of the ceramic combination layer and the bulletproof fiber layer is, and therefore, the larger the attaching difficulty is, the larger the number of the micropore riveting structures selected by the central control device is.
Particularly, the central control device performs sound transmission detection on the combined part formed by combining the ceramic combined layer and the bulletproof fiber layer, when the sound transmission speed of the combined part acquired by the central control device is less than or equal to a first preset sound transmission speed standard value, the compactness of the combined part at the moment is far lower than a preset standard, because the micropore riveting structure is used for reinforcing the combined part, the compactness is far lower than the preset standard because the ceramic combined layer has a problem, and the tightness of the combination between the ceramic plates does not accord with the preset standard, so the central control device judges to increase the driving force of the pushing device to ensure that the compactness of the combined part formed next time accords with the preset standard, when the sound transmission speed acquired by the central control device is greater than the first preset sound transmission speed standard value and is less than a second preset sound transmission speed standard value, the compactness of the combined part at the moment is lower than the preset standard value, however, the number of the microporous riveted structures for reinforcement is determined to be increased by the central control device to enable the compactness of the formed assembly to meet the preset standard, when the sound transmission speed acquired by the central control device is greater than or equal to a second preset sound transmission speed standard value, the performance of the assembly meets the preset standard, and modified thermosetting resin is respectively introduced into the surface of the ceramic composite layer of the assembly and the bulletproof fiber layer to form the composite bulletproof ceramic.
