Properties and microstructure of KD-I/SiC composites by combined process of CVI/RB/PIP

Mechanical behavior of SiCf/SiC composites with alternating PyC/SiC multilayer interphases

“…Typical properties and surface morphology of the KD-I SiC fiber can be found in Refs. [19,23]; and further information including raw materials, processing, chemical composition, and tensile strength distribution, etc. can be found in the literature [24][25][26][27].…”

“…engineering an appropriate interfacial layer between the fiber and matrix, which can prevent the fiber from being corroded, enable efficient load transfer between the fiber and matrix, and arrest or deflect the crack propagation in the matrix [16][17][18]. In this context, Zhu et al [19] studied the microstructure and mechanical properties of 3D KD-I/SiC composites fabricated by a combined chemical vapor infiltration (CVI), reaction bonding (RB) and PIP process using Al as an active filler. The interphases employed consisted of one layer of pyrolytic carbon (PyC) and one layer of SiC with different thicknesses.…”

SiC fibers with controllable thickness of carbon layer prepared directly by preceramic polymer pyrolysis routes

“…There is a continuous interest in silicon carbide (SiC) fibers pyrolyzed from preceramic polycarbosilane (PCS) that can be widely applied as the refractory reinforcements for plastic-matrix composites (PMCs) [1], metal-matrix composites (MMCs) [2,3] and ceramic-matrix composites (CMCs) [4,5]. This is mainly because of their excellent fracture strength, stiffness and high temperature resistivity in oxidizing atmosphere.…”

Microstructure, mechanical properties and reaction mechanism of KD-1 SiCf/SiC composites fabricated by chemical vapor infiltration and vapor silicon infiltration

“…However, they are difficult to be widely used due to their high cost and limited production. Thus, a kind of available KD-1 SiC fiber (from National University of Defense Technology, China) was employed as reinforcement in our work [8].…”
