These CMCs_x000D_
are made with silicon carbide (SiC) ceramic fiber embedded in a SiC matrix material. The SiC ceramic fibers_x000D_
forming the yarns are highly stiff and brittle. During all yarn handling operations (e.g., coating, spooling, etc.),_x000D_
yarns undergo a moderate level of damage. This damage accumulates and has a detrimental effect on both part_x000D_
quality and yield. This project's objective is to develop a modelling approach to understand the fiber damage_x000D_
mechanisms during yarn processing. A parametric non-linear quasi-static finite element model will be created_x000D_
in Abacus to represent yarn handling situations. A small test rig composed of a feed yarn spool, several friction_x000D_
surfaces and a take-up spool be designed and built. The rig will reproduce fiber damage creation mechanisms_x000D_
and will help validate the modelling approach. A friction accumulation quantity will be determined from the_x000D_
modelling and testing. This quantity will be used to explain damage creation and assess fiber processing_x000D_
equipment design. The model files and a report will be delivered. With this project, we will develop modelling_x000D_
approaches to understand fiber-fiber and fiber-surface friction interactions. GE Aviation Bromont will expand_x000D_
