Steel fiber textile reinforced mortar reinforced composite material with gradient interface and preparation method thereof
The invention provides a steel fiber textile reinforced mortar reinforced composite material with a gradient interface and a preparation method of the steel fiber textile reinforced mortar reinforced composite material with the gradient interface, and the steel fiber textile reinforced mortar reinforced composite material with the gradient interface is composed of mortar, resin, steel fiber textile, resin and mortar. The tensile strengths of the components are sequentially mortar, resin and steel fiber textile from small to large, so that a gradient interface is formed at the interface. The preparation method of the composite material comprises the following steps: firstly, pouring a layer of mortar in a mold, coating the surface of the mortar with a layer of resin, then pressing the steel fiber textile on the surface of the resin, coating the upper surface of the steel fiber textile with a layer of resin, and finally, pouring a second layer of mortar. The prepared steel fiber textile reinforced mortar reinforced composite material is good in mechanical property, large in interface bonding strength and not prone to layering, the problem that top layer mortar is stripped when the steel fiber textile reinforced mortar reinforced composite material is stressed is solved, and the construction method is simple and not affected by external factors.
本发明提供一种具有梯度界面的钢纤维纺织品增强砂浆加固复合材料及其制备方法，该具有梯度界面的钢纤维纺织品增强砂浆加固复合材料由“砂浆‑树脂‑钢纤维纺织品‑树脂‑砂浆”组成，它们的拉伸强度从小到大依次为砂浆、树脂和钢纤维纺织品，因此在界面处形成梯度界面。该复合材料的制备方法为：首先在模具中浇筑一层砂浆并在其表面涂覆一层树脂，然后将钢纤维纺织品按压在树脂表面并在其上表面再涂覆一层树脂，最后浇筑第二层砂浆。本发明制备的钢纤维纺织品增强砂浆加固复合材料力学性能好，界面粘结强度大不易分层，改善了钢纤维纺织品增强砂浆加固复合材料受力时顶层砂浆剥离的问题，并且施工方法简单，不受外界因素影响。
