Joint IPCF-CNR/DICI-UNIPI Laboratory for Microwave Assisted Chemical Vapour Infiltration (MW-CVI) of Ceramic Matrix Composites (CMCs)

Silicon carbide based (SiC) Ceramic Matrix Composites (CMCs) represent one of the most promising solutions for high-temperature applications in strategic industrial sectors such as transport and energy. Due to the extremely high cost, their use is still limited only to high end applications so new and more efficient manufacturing technologies are needed in order to reduce production costs and expand their use.

An innovative hybrid Microwave assisted Chemical Vapor Infiltration (MW-CVI) pilot plant was designed, built and setup, as a part of the European project HELM.

Research activities are mainly focused on:

  • Study and production of SiC-based CMCs through MW-CVI technology as an economic and sustainable solution;
  • Modeling of EM-Thermal problem to achieve homogeneous heating conditions and predict power requirements and final sample’s temperature profile
