Description
  • An efficient approach to the evaluation of effective thermal conductivity of carbon-carbon (C/C) plain weave textile composites using the Mori-Tanaka (MT) method is presented. The method proves its potential even if applied to real orthotropic material systems with various types of imperfections including the non-uniform waviness of the fibre-tow paths. Uncertainties linked to other geometrical parameters are mostly reflected in the derivation of an optimal shape of the equivalent ellipsoidal inclusion using a family of ideal periodic unit cells (PUC). Evaluation of the effective properties in the absence of pores is presented first. Ellipsoidal pores are then introduced in the second step into a new homogenized matrix to account for the presence of large vacuoles in the composite. Several examples are presented to demonstrate this approach.

  • V příspěvku je prezentováno určení efektivních tepelných vlastností tkaných kompozitů uhlík/uhlík s využitím metody Mori-Tanaka. Geometrická složitost tohoto materiálového systému je brána v úvahu při vytváření representativního vzorku (periodické buňky) využitím informací získaných obrazovou analýzou skutečného materiálu. Vhodnost využití metody Mori-Tanaka je demonstrována porovnáním výsledků s daty získanými buď experimentálně nebo pomocí konečně prvkového řešení. (cs)
