GB/T 40398.2-2021 Translated English of Chinese Standard (GB/T40398.2-2021, GBT 40398.2-2021): Test method for C-C composites -- Part 2: Flexural properties [Buy--download True-PDF in 3-second: https://play.google.com/books > Sign in > This BOOK > "3-dots" > Export > Save as "*.pdf"]https://www.chinesestandard.net, 2022 M08 21 - 13 pages This document specifies the principle, equipment, samples, test conditions, test procedures, calculation and test report of the test method for the flexural properties of C-C composites at room temperature. This document applies to the determination of flexural strength and flexural modulus of punctured three-dimensional C-C composites and needled quasi-three-dimensional C-C composites at room temperature. It also applies, as a reference, to C-C composites of similar structure. |
