Alkali-resistant glass fiber composite rib for concrete and preparation method thereof

JIAO YUZHAO / CHEN WENXUE

The invention relates to the technical field of fiber reinforced composite materials, in particular to an alkali-resistant glass fiber composite rib for concrete and a preparation method of the alkali-resistant glass fiber composite rib. The alkali-resistant glass fiber composite rib for the concrete is obtained by dipping composite alkali-resistant glass fiber bundles in bonding resin and carrying out pultrusion, the composite alkali-resistant glass fiber bundle is formed by bundling alkali-resistant glass fibers into an alkali-resistant glass fiber bundle with the diameter of 2 +/-0.3 mm, then dipping the alkali-resistant glass fiber bundle into reaction type resin slurry, and carrying out traction, drying, curing and collection to obtain the composite alkali-resistant glass fiber bundle. The alkali-resistant glass fiber composite bar for concrete prepared by the invention has excellent mechanical properties, high temperature resistance and alkali resistance, can partially replace steel bars to prepare concrete, and is widely applied to ocean engineering.

本发明涉及纤维增强复合材料技术领域，具体涉及一种混凝土用耐碱玻璃纤维复合筋及其制备方法。所述混凝土用耐碱玻璃纤维复合筋由复合耐碱玻璃纤维束浸渍于粘结树脂中，经拉挤成型得到；所述复合耐碱玻璃纤维束由耐碱玻璃纤维集束成直径为2±0.3mm耐碱玻璃纤维束，再浸渍于反应型树脂浆料中，经牵引，烘干固化，收集得到。本发明制备的混凝土用耐碱玻璃纤维复合筋具有优异的力学性能、耐高温性能和耐碱性能，可部分替代钢筋用于制备混凝土，广泛应用于海洋工程中。
