High creep strength
WebCreep strength and fracture resistance are two properties that are critical in the selection and optimization of high temperature materials. These same properties may be progressively impaired by service exposure and are, therefore, key to the assessment of remaining life of high temperature components. Web14 de abr. de 2024 · Fiber reinforced polymer (FRP) composites, as one of the most rapidly developing materials, are favored because of high specific strength and specific modulus, fatigue resistance, and light weight properties compared with traditional materials [1, 2].FRPs have been widely utilized in the field of civil engineering for the strengthening of …
