１ＦＲＰ筋的类别ＦＲＰ由高性能的纤维和基材组成。基材为聚酯（与玻璃纤维一起使用）、环氧等。而纤维一般为５～２０μｍ直径的连续纤维。纤维的种类有碳纤维、玻璃纤维和芳纶纤维等。现在常使用的ＦＲＰ筋有以下三种 :玻璃纤维增强塑料（ＧＦＲＰ）筋、碳纤维增强塑料（Ｃ
1FRP Rib Category FRP consists of high-performance fibers and substrates. The substrate is polyester (used with glass fibers), epoxy and the like. The fibers are generally 5 ~ 20μm diameter continuous fibers. The types of fibers are carbon fiber, glass fiber and aramid fiber. There are three types of FRP bars that are commonly used today: glass fiber reinforced plastic (GFRP) bars, carbon fiber reinforced plastics (C
