Abstract
The production processes of ceramic matrix composites require innovation, as usually they are quite time consuming. The introduction of high-frequency electro-magnetic technologies can allow the reduction of processing time that directly will reduce energy costs, up to now mainly affecting the final material cost. The integration of microwave and radio-frequency technologies to conventional heating in the innovative production plants of chemical vapour infiltration (CVI), Liquid Silicon Infiltration (LSI), graphite expansion (GE) and polymer impregnation and pyrolysis (PIP) resulted much interesting on a technological point of view and leaded to the design and building of innovative laboratory prototypes in the framework of HELM European Project.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
