The utility model discloses a kind of high folding-resistance composite
black card paper, including card paper base paper layer, the quantity of card paper base paper layer is two, and one side of two card paper base paper
layers adjacent is respectively fixedly connected with reinforcing frame and reinforcing plate, the top of reinforcing plate is respectively fixedly connected with work shape frame and anti-bending
pipe, work shape frame and anti-bending
pipe are all fixedly connected with reinforcing frame.The utility model is formed rectangle using reinforcing frame and reinforcing plate, the device has the characteristics of bending resistance using work shape structure, circular structure and rectangular mechanism, and the bending resistance effect of the device is greatly improved, the device is made of multiple materials, has the advantages of high strength and good resilience, so that it is not easy to bend, when it is bent to a certain degree, it can still rebound to its original shape using the resilience of the device itself, and the stability of the shape is maintained, and the folding resistance of the device is improved, the device has the
advantage of good folding resistance.
