Zero-dimensional and one-dimensional micro-nano filler synergistic reinforcing and stiffening resin and preparation method thereof

The invention discloses zero-dimensional and one-dimensional micro-nano filler synergistic reinforcing and stiffening resin and a preparation method thereof. The resin comprises an epoxy resin monomer, an aromatic amine curing agent, inorganic nanoparticles and inorganic micro-nano fibers. According to the resin, the micro-nano filler which contributes to improvement of the strength modulus of a resin system is selected, different dispersion modes are adopted, the proportion of the micro-nano filler is controlled, and on the basis that the comprehensive performance such as resin viscosity and operation manufacturability is considered, the purpose of synergistic reinforcing and stiffening is achieved; the bending strength of the resin casting body is greater than 180 MPa, and the bending modulus is greater than 5.5 GPa. 本发明公开了一种零维与一维微纳填料协同增强增刚树脂及其制备方法。该树脂包含环氧树脂单体、芳香胺固化剂、无机纳米颗粒、无机微纳纤维。该树脂通过选取对树脂体系强度模量提升贡献各异的微纳填料，采用不同的分散方式并控制其比例，在兼顾树脂粘度和操作工艺性等综合性能的基础上，达到协同增强增刚的目的；该树脂浇铸体弯曲强度强度大于180MPa，弯曲模量大于5.5GPa。
