Ceramic Matrix Composite Parts Marking

Ceramic matrix composites (CMCs) offer improvements in durability, higher temperature capability and reduced weight. Rapid, reliable, and cost effective parts marking technology is necessary for in-process tracking and parts flow optimization, but the process is complicated for CMCs, given the high temperature exposures they are subject to during processing and in-service. The overall objective of this Phase II effort is to develop and manufacture a prototype laser marking/mark interpretation system for installation at a manufacturer of CMCs and components. The effort is divided into a base and an option effort. During the base effort, the laser marking and automatic interpretation processes will be validated and elements such as minimum marking depth, post marking material properties, optimal laser characteristics, and accuracy and repeatability of the technology will be quantified. The option effort will culminate in the demonstration of the prototype laser marking system on the factory floor processing actual aerospace components following a full sequence of polymer infiltration and pyrolysis manufacturing steps to track parts in service through multiple high temperature exposures. Ex One is partnered with ATK, a supplier of aerospace and defense products who will provide sample materials, components and evaluation and Pratt & Whitney, Rolls-Royce and General Electric.
