ANTI-EXPLOSION AND ANTI-IMPACT MULTI-STAGE HETEROGENEOUS FIBER PREFORM COMPOSITE CONCRETE AND PREPARATION METHOD THEREFOR

WIPO Patent Application WO/2021/077667

A1

Disclosed are anti-explosion and anti-impact multi-stage heterogeneous fiber preform composite concrete and a preparation method therefor. A plurality of layers of multi-stage heterogeneous fiber preforms that are arranged in parallel are arranged in the anti-explosion and anti-impact concrete. Each of the multi-stage heterogeneous fiber preforms is formed by means of warp-weft plain weaving of a plurality of multi-stage heterogeneous fibers. The multi-stage heterogeneous fibers are formed by winding multi-stage auxiliary fibers around a core fiber, wherein the core fibers are low-modulus fibers, and the multi-stage auxiliary fibers are high-modulus fibers with different elastic moduli. According to the anti-explosion and anti-impact concrete, by means of gradient type spiral design and three-dimensional layered arrangement of the multi-stage auxiliary fibers in the preforms, the negative Poisson's ratio effect of the preforms is remarkably improved, and is effectively exerted in a matrix.
