MAI CeMCut – Analysis and assesment of component quality and damage mechanism after finishing of fiber-reinforced ceramics (C/SiC, SiC/SiC)

Coordinator:

Prof. Dr.-Ing. Ralf Goller

Funding:

Funded by the Federal Ministry for Economic Affairs and Clima Action (Bundesministerium für Wirtschaft und Klimaschutz (BMWK)) on the basis of a resolution of the German Bundestag

IGF – Collective Industrial Research (Industrielle Gemeinschafts­forschung)

Project Duration:

01.03.2021 - 31.10.2023

Project Description:

The MAI CeMCut project investigates the component quality during the mechanical finishing of non-oxide fibre-reinforced ceramics (CMC). For that purpose the emerging damage mechanisms are described, the arising imperfections are classified and their effect on the component quality is analyzed.

The final goal of the research project is to provide user guidelines in form of a "CMC machining manual", in which the correlation between material parameters and machining parameters is further explained. Subsequently in MAI CeMCut the submission of a standard proposal for a "DIN SPEC End Machining" for CMC to the Committee for Standardization is planned.

The results of the research project will be implemented by CMC material manufacturers, manufacturers of machining tools for CMC as well as by CMC processors and end users. By knowing the appropriate machining parameters, a reduction of the rejected components and an increase in component safety during use is possible. Thereby a resource-efficient processing with reduced costs can be achievable.
