Puncture-resistant flexible nano composite material and preparation method thereof

The invention discloses a puncture-resistant flexible nano composite material and a preparation method thereof.The composite material is formed by compositing a weft knitting base body with shear thickening fluid, the compactness degree of the base body is 14-49.5, the base body is made of ultra-high molecular weight polyethylene, the yarn count is 200D-600D, the transverse density of the base body is 18-30 wale lines per inch, and the thickness of the base body is 20-30 mm. And the longitudinal density is 30-43 rows per inch. Preferably, the yarn count is 300D-590D, the transverse density of the base body is 23-30 rows per inch, and the longitudinal density of the base body is 30-40 rows per inch. The composite material can effectively resist needle puncture and is good in flexibility, fine operation of the hand of a user is not affected, and an ideal needle puncture resisting effect can be achieved through a single-layer material. The preparation process is simple, and mass production can be realized. Green
