Abstract
Apart from their use for reinforcing polymers (1), during the past few years carbon fibers have also gained importance as a reinforcing component for carbon artifacts, the reason being that the full potential of carbon fibers can be exploited only in connection with a high temperature matrix such as carbon (2), The principal problem in fabricating carbon-carbon composits lies in the shrinkage of the matrix during the pyrolysis. In this paper, an investigation is described to which extent this shrinkage affects the structural integrity and the mechanical properties of the composites, and what measures are required for prventing or eliminating any damage of the fiber and the matrix as well as the binding between both. This damage by the matrix shrinkage is expected to be smaller if a plastic deformation of the matrix during the pyrolysis is possible. The analysis of the shrinkage effect discussed in Part 1 is limited to the study of the behavior of thermosetting resins. The manufacture of carbon-carbon composites using thermosetting as well as thermoplastic binder precursors is described in Part 2.
