Problems solved by technology

As far as the polymer materials are concerned, although the common ultra-high molecular weight polyethylene fibers, polyamide fibers and PBO fibers have good bulletproof and stab-proof properties, they all have defects, for example: ultra-high molecular weight polyethylene fibers are not resistant to Heat, the maximum temperature resistance is below 120 °C; polyamide fibers are not resistant to ultraviolet light and moisture, and these materials have high mass density
Therefore, these materials are difficult to meet the application requirements in some fields. For example, when used as personal protective materials, the protective structure formed by them is thick, poor wearing comfort, airtight, and affects human activities and flexibility.
