The invention discloses an alkali-resistant glass fiber reinforced plastic (AR-GFRP) rib. The AR-GFRP rib comprises a core part and a coating part, the core part comprises the following components in percentage by weight: 70-85% of glass fiber, 12-28% of resin and 2-8% of an additive; the coating part comprises the following components in percentage by weight: 70-85% of alkali-resistant glass fiber, 12-28% of resin and 2-8% of an additive. The alkali-resistant glass fiber reinforced composite material rib is high in corrosion resistance, the weakening phenomenon generated when the rib is soaked in seawater is small, and the life cycle of an engineering structure can be prolonged. 本发明公开了一种耐碱玻璃纤维增强复合材料(AR-GFRP)筋，包括：芯部和包覆部；按重量百分比计，所述芯部的组成包括：70-85％玻璃纤维、12-28％树脂以及2-8％添加剂；按重量百分比计，所述包覆部的组成包括：70-85％耐碱玻璃纤维、12-28％树脂以及2-8％添加剂。本发明的耐碱玻璃纤维增强复合材料筋抗腐蚀能力强、在海水中浸泡产生的弱化现象小，可提高工程结构的生命周期。
