摘要
利用超声衰减的原理,运用超声C-扫描成像技术超声表征评定树脂基复合材料的孔隙大小,进而评定材料的力学性能情况,结合解剖试验建立了树脂基复合材料超声衰减、孔隙率和力学性能的关系曲线,探索了一种超声表征评定树脂基复合材料的孔隙情况及力学性能的方法。
The principle of ultrasonic attenuation measurement is introduced.Ultrasonic C-csan imaging characterization of porosity in fiber-reinforced composites was used to evaluate the mechanical properties of the materials.The relationships of ultrasonic attenuation,the void content and mechanical properties were described associating the destructive analyzing of the samples.A ultrasonic characterization method was explored in the field of evaluating the porosity and mechanical properties in fiber-reinforced compo...
