Basalt fiber reinforced structure type chopped micro rib
The invention relates to a basalt fiber reinforced structure type chopped micro rib, and aims to solve the problem that an existing micro rib is easy to untwist. The basalt fiber reinforced structure type chopped micro-rib is formed by heating and curing a fiber material and an epoxy resin matrix which are used as adhesives; in the length direction of the micro-rib, the two ends of the micro-rib are of flat-sheet-shaped structures, and the surface of the main body part between the two ends of the micro-rib is provided with spiral textures. And after the end part of the twisted micro-rib is compacted and flattened, the problem of local degumming and loosening of the original common twisted micro-rib is solved, and the effect of common stress of the fiber bundles in concrete is enhanced. Meanwhile, when the fiber concrete is stressed, the special-shaped structure at the end part of the micro-rib enhances the bond stress of the whole micro-rib in the concrete on one hand, and avoids or delays the phenomena of fiber exposure and fuzzing caused by resin abrasion on the other hand, so that the bonding-sliding performance of the fiber in the concrete is enhanced; therefore, the bridging effect of the fiber in the concrete is more obvious, and the ductility of the fiber concrete is further enhanced.
本发明涉及一种玄武岩纤维增强结构型短切微筋，旨在解决现有微筋易发生解捻。玄武岩纤维增强结构型短切微筋，由纤维材料与环氧树脂基为粘合剂加热固化形成；沿微筋长度方向，微筋两端为扁片状结构，微筋两端间的主体部位表面呈现螺旋状纹理。当加捻型微筋端部进行压实扁片化处理后，解决了普通加捻型微筋原生的局部脱胶松散问题，加强了纤维束在混凝土中共同受力的效果。同时，当纤维混凝土受力时，微筋端部的异型构造一方面增强了微筋整体在混凝土中的握裹力，另一方面避免或延缓了因树脂磨损导致的纤维露出和起毛现象，增强了纤维在混凝土中的黏结‑滑移性能，从而使纤维在混凝土中的桥联作用更为显著，进一步增强了纤维混凝土的延性。
