[0064] Among them, Pmax is the load on the functional fabric at the maximum tensile strength, and A0 is the original cross-sectional area of the functional fabric. It is worth mentioning that for brittle materials, the maximum tensile strength is an important mechanical property; however, for ductile materials, the maximum tensile strength value is not commonly used in industrial design, because before reaching this value, the material Significant plastic deformation has occurred.

Furthermore, since the plastic optical molding material disclosed in the embodiment of the present invention can be selected from the recycling material of cycloolefin macromolecule, the manufacturing cost of the functional cloth can be reduced, and the recycling of waste and the environmental protection and energy saving can be achieved. the goal of.

The above is only the preferred feasible embodiment of the present invention, and is not intended to limit the protection scope of the present invention, and all equal changes and modifications made according to the scope of the present invention should belong to the claims of the present invention. scope of protection.
