This study investigated the bond properties and stress-slip relations between glass-fiber-reinforced plastic (GFRP) bars and hybrid fiber-reinforced concrete (HFRC) containing carbon, aramid and polypropylene fibers, and explored the effects of fibers-volume fraction, bar diameter, anchorage length and surface configuration. A total of 48 samples, including 36 HFRC samples with embedded GFRP bars and 12 ordinary concrete (OC) samples with embedded GFRP bars, were manufactured and subjected to pullout tests. The test results indicated that the bond behavior between the GFRP bars and HFRC was significantly improved by the cooperative effects of the carbon, polypropylene and aramid fiber. A bond-slip constitutive model for the GFRP bars embedded in both HFRC and OC was established and had a good agreement with the testing results.

本研究研究了玻璃纤维增​​强塑料（GFRP）筋与含碳，芳纶和聚丙烯纤维的混合纤维增强混凝土（HFRC）之间的粘结性能和应力滑移关系，并探讨了纤维体积分数，棒的影响直径，锚固长度和表面形状。总共制造了48个样品，包括36个带有嵌入GFRP棒的HFRC样品和12个带有嵌入GFRP棒的普通混凝土（OC）样品，并进行了拉拔测试。测试结果表明，碳，聚丙烯和芳纶纤维的协同作用显着改善了GFRP条与HFRC之间的粘结行为。建立了嵌入在HFRC和OC中的GFRP筋的粘结滑移本构模型，与试验结果吻合良好。
