Abstract

Tensile fracture behavior of ceramic matrix composites (CMCs) was investigated using characterization tools. First, a high-speed infrared camera was used to monitor the surface temperature of the CMC specimen during mechanical testing. An infrared camera is a tool used to detect infrared (IR) radiation emitted from a specimen as a function of temperature, and it was used to analyze the temperature monitoring of specimen surface and fracture behavior during the tensile test. After the test, the microstructural analysis using SEM was performed. SEM analysis was performed to investigate the fracture mode and fracture mechanism of CMC materials. In this paper, it was found that the results of the surface temperature monitoring obtained from IR thermal imaging technology and the failure mode analysis obtained through SEM were in a good agreement. These techniques were useful tools to explain the mechanical behavior of ceramic matrix composites. The detailed experiments and testing results will be provided.

Summary

Introduction

Ceramic matrix composites are spotlighted for high temperature structural applications [1,2]. Ceramics are useful materials for high temperature materials due to their high strength, high temperature and corrosion resistance. They are lightweight, but their use is limited because of their unique brittle characteristics. In order to compensate for such brittleness and to increase fracture toughness, various types of fibers could be reinforced to form ceramic composite materials [1,2,3,4]. Ceramic composites reinforced with continuous fibers are widely used in practical applications, for example, heat exchangers, high temperature blades, automotive brake discs, jet engines, surface parts of spacecraft, etc. Ceramic composites reinforced with continuous fibers are widely used in practical applications, for example, heat exchangers, high temperature blades, automotive brake discs, jet engines, surface parts of spacecraft, etc. [1]
