摘要

采用两段前驱体渗透热解(PIP)工艺制备了SiCf/SiC复合材料。采用C3-BN和C3-BN-1800两种SiC纤维作为增强材料。C3-BN是包覆原位氮化硼(BN)层的第三代SiC纤维,C3-BN-1800是由C3-BN在1800℃下连续热解1 min得到的。在第一阶段,SiCf/SiC复合材料(CMC-Is)通过低温PIP工艺实现初始致密化,基体由低结晶度SiC和无定形SiOxCy组成。在1600℃-1 h时,SiC基体的结晶和SiOxCy的分解导致CMC-Is的强度显著降低(强度保留30%)。通过多次高温PIP工艺(第二阶段),SiCf/SiC复合材料(cmc -II)的密度高于cmc - i,基体具有高结晶度的SiC,氧含量显著降低。因此,cmc - ii具有较好的耐热性,在1600°C-10 h时强度保持率接近50%。

Effects of in-situ BN coating on thermostructural properties of SiCf/SiC composites prepared via PIP process

SiCf/SiC composites were fabricated by a novel two-stage precursor infiltration and pyrolysis (PIP) process. The two types of SiC fibers (C3-BN and C3-BN-1800) were used as reinforcements. The C3-BN was the third-generation SiC fibers coated with an in-situ boron nitride (BN) layer, C3-BN-1800 was obtained by a 1 min continuous pyrolysis of C3-BN at 1800 °C. In stage I, the SiCf/SiC composites (CMC-Is) achieved initial densification by low-temperature PIP process, while the matrix consisted of low crystallinity SiC and amorphous SiOxCy. At 1600 °C-1 h, the crystallization of SiC matrix and decomposition of SiOxCy led to a significant reduction in the strength of the CMC-Is (30% strength retention). Through several cycles of high-temperature PIP process (stage II), the SiCf/SiC composites (CMC-IIs) had higher density than CMC-Is, and the matrix had high crystallinity SiC and significantly decreased oxygen content. Thus the CMC-IIs have better thermal resistance and the strength retention is near 50% at 1600 °C-10 h.
