Abstract
The present paper describes experimental and numericalwork for the evaluation of
the selected effective mechanical and transport material properties of polysiloxane
matrix based composites. Three different material systems including carbon, basalt
and glass plain weave textile reinforcements are first studied experimentally with
emphasis on the influence of processing temperature, number of reinforcement
layers and the resulting porosity. The Mori–Tanaka averaging scheme is then
selected for the numerical evaluation of effective electric conductivities adopting
the standard bottom-up hierarchical homogenization.
Keywords: homogenization, ceramic textile composites, Charpy test, falling test,
electric conductivity, porosity, Mori–Tanaka method.
1 Introduction
Textiles are no longer a sole realm of clothing industry but diffuse in many other
lines of business and branches of science. Nowadays, an increasing number of fiber
reinforced composite components are being fabricated with load-carrying fibers,
which are woven to form a fabric. This reinforcement system has advantages with
respect to fabrication as well as mechanical properties.
In this regard, carbon-carbon (C/C) textile composites have enjoyed a
considerable interest as potential candidates for high-tech applications including
rocket industry on the one hand and bone-surgery on the other hand.However, their
expansion into points of practical applications has been obstructed by a number of
