In order to eliminate the disadvantage of neat polyvinyl alcohol (PVA) on cementitious composites, PVA hybrid fibers containing graphene oxide and dispersed silver nanoparticles were prepared and its effect on cementitious composites properties was investigated with the help of principal component analysis. Test results show that an increment ratio was obtained in fracture toughness and electrical resistivity of 47.25% and 88.13% of fiber reinforced mortar with PVA based graphene oxide and silver nanoparticles blended hybrid fibers, respectively. The findings also demonstrated that film thickness and surface roughness have a significant impact on fracture toughness and electrical resistance of fiber reinforced mortars.

为了消除纯聚乙烯醇（PVA）对水泥基复合材料的不利影响，制​​备了含有氧化石墨烯和分散的银纳米粒子的PVA杂化纤维，并通过主成分分析研究了其对水泥基复合材料性能的影响。试验结果表明，在纤维增强砂浆中掺入PVA基氧化石墨和银纳米颗粒混合杂化纤维后，断裂韧性和电阻率分别提高了47.25％和88.13％。研究结果还表明，膜厚和表面粗糙度对纤维增强砂浆的断裂韧性和电阻有显着影响。
