| 摘 要： | 利用XRD,SEM,EDS研究浆料浸渍结合反应熔渗法制备2D C/SiC-ZrB2复合材料的组成与结构,并测定了复合材料的弯曲强度.结果表明:采用单向加压依次渗入ZrB2微粉和酚醛树脂,能很好地将ZrB2微粉和树脂渗入到纤维束间,但熔融Si难以渗入到试样内部,复合材料的开气孔率和室温弯曲强度分别为18.3%和110MPa.采用ZrB2浆料真空浸渍,沉积碳基体后进行熔融渗Si,复合材料的开气孔率和室温弯曲强度分别为5.5%和230MPa.

| Abstract: | 2D C/SiC-ZrB2 composites were prepared by combining slurry infiltration technology with reactive melt infiltration method.The phase identification and microstructure of the composites were analyzed by XRD,SEM and EDS.Mechanical properties were evaluated by three-point flexural test.The results show that when ZrB2 powder and phenolic resin is infiltrated in turn under single-oriented pressure,they can be satisfactorily infiltrated into inter-bundles.But during the reactive melt infiltration precess,Si can no... |
