Mechanical behaviour of polymer derived ceramics – a review

Abstract

Since the last five decades, polymer-derived ceramics (PDCs) are in use and envisaged for a variety of applications. The transition of a precursor to an inorganic ceramic by pyrolysis and heat-treatment results in either amorphous or nanocrystalline composites with the evolution of phases strongly controlled by the processing conditions. Understanding the deformation behaviour under ambient conditions and at elevated temperatures is key to designing these materials for long-term use. However, quantitative reliable estimation of mechanical properties is quite challenging due to its unique structure which in turn is strongly governed by the precursor chemistry. The mechanical behaviour of PDCs in the form of fibres, bulk and foams are different and they are discussed separately. Both experimental and simulationbased studies are considered in this review. Recently, additive manufacturing processes have been used for the fabrication of PDCs, the mechanical properties of which are also included in this review.

Flexible Mo2C‐Modified SiC/C Nanofibers for BroadBand Electromagnetic Wave Absorption

“…Due to the ambient conditions, low cost, easy operation, and time saving, SiC ceramic was usually prepared by polymerderived ceramics (PDCs) method. [1][2][3] SiC ceramic with various structures, such as fiber, coating, film, and foam, can be obtained through this technology. Usually, SiC ceramic with high resistivity and nonmagnetic properties is a typical electromagnetic (EM) wave transmission material.…”

Grignard coupling-based synthesis of vinyl-substituted hydridopolycarbosilane: effect of starting material and polymerization behavior

“…3,4 While polycarbosilane is originally known to be a precursor to SiC bers, these modied polymers are mainly applied to additive manufacturing or PIP (polymer inltration and pyrolysis) process. [5][6][7] As the industrial eld to which the polymer derived ceramics (PDC) technology applied is rapidly advanced, interest in preceramic polymer is growing again. In order to develop application-specic processes, polycarbosilane with proper properties is needed, but there is a limit to the use of commercial products.…”
