    • Fibers, continuous or discontinuous, and bars having optimized geometries for use in the reinforcement of cement, ceramic and polymeric based matrices are claimed. The geometries are designed to increase the ratio of surface area available for bond between the fiber and the matrix to the cross-sectional area of fiber. In the case of a continuous reinforcement comprised of a single fiber or a bar made out of a bundle of fibers, such as is the case in reinforced and prestressed concrete, increasing the surface area available for bond leads to a decrease in crack width, development length, and transfer length. The fibers or bars are also configured to be amenable for twisting or to have spiral like deformations along their longitudinal axis to further develop the mechanical component of bond between the fibers and the matrix. Additional methods of mechanical bond enhancement, such as crimping and/or addition of anchorages, such as hooked ends, paddles, buttons, etc., can be applied to the claimed fibers to further improve their bond characteristics.
    • 声称连续或不连续的纤维和具有优化几何形状的棒用于水泥,陶瓷和聚合物基质的增强。 几何形状被设计成增加可用于纤维和基体之间的结合的表面积与纤维的横截面面积的比率。 在由纤维束制成的单根纤维或棒制成的连续加固的情况下,例如在增强和预应力混凝土中的情况,增加可用于粘结的表面积导致裂缝宽度的减小,开发 长度和传送长度。 纤维或条还被构造成适于扭曲或沿其纵向轴线具有螺旋形变形,以进一步发展纤维和基质之间的机械结合部分。 附加的机械结合增强方法,例如压接和/或添加锚固件,例如钩形端部,桨叶,钮扣等,可以应用于要求保护的纤维,以进一步改善它们的粘合特性。
