A Review on Si-Based Ceramic Matrix Composites and their Infiltration Based Techniques

Abstract

This review paper aims to look at silicon-based ceramic matrix composites and infiltration-based approaches for them. There are many different types of infiltration-based manufacturing processes, each with its own set of features. The best technique is chosen depending on the needs and desired attributes. With these considerations in mind, any type of infiltration might be selected to meet the requirements. Silicon-based ceramics has been highly used in the fields of aerospace, medical, automobile, electronics, and other various industries so it is important to study about their applications as well. This review outlines the evolution of composites from early 7000 BCE to composites today and discussed about various infiltration techniques for manufacturing silicon based ceramic matrix composites. This article also gives the comprehensive review of general characteristics and mechanical properties of silicon-based composites used in a variety of engineering sectors. The application section entails the wide range of engineering fields with consideration of infiltration techniques, which would be helpful for researchers to study and correlate the different infiltration techniques for end applications.

Interfacial Fracture Behavior and Adhesive Strength in Tensile and Shear Loading of SiC-PyC-SiC Composites by Micro-Scale Specimens

“…Ceramic fiber matrix composites (CFMC) are being considered for a range of structural components due to their variety and flexibility in shape and design, their high temperature mechanical performance as well as low weight [1][2][3][4][5]. The enormous progress made recently in fabricating high-quality, pure silicon carbide (SiC) fibers enables a large-scale production that is economically viable.…”

Ceramic Matrix Composites: Classifications, Manufacturing, Properties, and Applications

“…In this stage, the matrix material is introduced into the preform construction to fill the gaps between the fibers and form the required composite structure. This can be achieved by using techniques like Polymer Infiltration and Pyrolysis (PIP), Liquid Silicon Infiltration (LSI), sol-gel infiltration, and Chemical Vapor Infiltration (CVI) [48].…”
