摘要： The invention relates to an aramid nanofiber composite unidirectional fabric and a preparation method therefor. The aramid nanofiber composite unidirectional fabric comprises unidirectional sheet layers, wherein the unidirectional sheet layers comprise aramid fibers arranged in a unidirectional mode and an adhesive; and the adhesive comprises aramid nanofibers. According to the aramid nanofiber composite unidirectional fabric, the bonding strength of the adhesive is improved, and the interface performance of the aramid fibers and the adhesive is improved. A bulletproof product prepared by cutting, laminating, compounding and molding the aramid nanofiber composite UD fabric has the advantages that the shrapnel impact resistance is improved despite the weight of the product not being greatly increased, and the safety index is higher.

摘要： Provided are a nanofiber composite unidirectional fabric and a preparation method therefor. The nanofiber composite unidirectional fabric according to the present invention comprises at least two unidirectional sheet layers and nanofibers located between adjacent unidirectional sheet layers. The unidirectional sheet layers each comprise unidirectionally arranged high-performance fibers and an adhesive, and the adhesive comprises nanofibers. The provided nanofiber composite unidirectional fabric has a novel composite structure, which integrates the comprehensive characteristics of fiber filaments, a resin matrix and nanofibers. The nanofiber composite unidirectional fabric of the present invention has excellent bulletproof performance and is suitable for novel bulletproof sheets.
