FAA Presented by L. Ilcewicz at 8/6/02 FAA/NASA Workshop for Composite Material Control2 Importance of Stabilizing Composite Materials for Safety and Efficiency Stable source of raw material is needed for continued safe and reliable use of composites in aircraft products Consistent engineering practices are needed to support requirements essential for base material control –Qualification database should be the statistical basis for equivalency (for new users and changes) and QC acceptance requirements –Documentation and databases should exist for each unique material –Property drift (including upward shifts) should be minimized Composite databases and specs shared throughout industry will improve the efficiency of suppliers, users and regulators

FAA Presented by L. Ilcewicz at 8/6/02 FAA/NASA Workshop for Composite Material Control3 Who Pays the Cost for a Lack of Standardization and Shared Databases? “Company Specifications: One of the major problems of aircraft repair today is that most airframe and engine manufacturers tend to write their own specifications, especially for adhesives, pre-pregs, potting compounds, and sealants. These are found in the various manuals as …, and others -- almost infinitum. This leads to a vast amount of duplicated testing by suppliers, who may have to test the same batch of material to three or more slightly different requirements and using slightly different test methods.” Page 257 of Care and Repair of Advanced Composite Materials, by Keith B. Armstrong and Richard T. Barrett, SAE International, 1998.

Center Reports and workshop discussions) –To be initially released through Small Airplane Directorate in Fall, 2002 The FAA policy will be released after a public review process, which includes posting in the Federal Registrar for final updates –To be considered in updating AC Quality Control for the Manufacture of Composite Structures (6/26/89, AIR 200) Work with SAE and Mil-Handbook-17 to develop approval processes for shared composite data and associated M&P specs Determine whether a TSO is needed to acknowledge FAA involvement in approving the control of composite raw materials

FAA Presented by L. Ilcewicz at 8/6/02 FAA/NASA Workshop for Composite Material Control18 Composite Material Qualification, Equivalency Testing, and Shared Databases The AGATE Program led to a need for FAA policy on those composite databases that can be shared by OEM & product users –Initial step towards standardized material control, with the associated base material properties and M&P specifications –Levels of “building block” testing that are not product design and manufacturing specific Three-step approach 1Multi-batch material qualification to generate the database & set specs. 2Equivalency (“mini-qualification”) to sample and show you process the material to fall within the database population and, if desired, update specs. per your specific use of material as allowed within guidelines 3Apply database to your product and continuously control the material

FAA Presented by L. Ilcewicz at 8/6/02 FAA/NASA Workshop for Composite Material Control21 FAA/NASA Workshop on Key Characteristics for Composite Material Control This workshop was intended to provide a forum where industry and government can discuss the most efficient ways to achieve composite material control

FAA Presented by L. Ilcewicz at 8/6/02 FAA/NASA Workshop for Composite Material Control22 Data and Process Requirements for Each Unique Stable Composite Material Process control document, PCD, used for raw material production (usually proprietary to the supplier) –Specify ingredients, quality controls and change policies Process specification applicable to the material –Portions of a process specification crucial to material control Test reports for properties measured in qualification Quality control acceptance criteria –Benchmark key characteristics based on a representative population (i.e., multi-batch, qualification databases ) –Incorporated into the material specification Storage and shipping limitations Material specification used for procurement

FAA Presented by L. Ilcewicz at 8/6/02 FAA/NASA Workshop for Composite Material Control23 Composite Material Procurement Specification Guidelines for development of material controls –Primary goals to help ensure consistent and stable materials –Specs and associated databases for each unique material –Allow industry freedom to pursue shared specs & databases for improved engineering efficiency and reduced costs Material requirements –Material supplier process control document (PCD) Control of prepreg ingredients & processes for producing the material Defines key material process parameters Statistical process control (SPC) –Fiber & resin properties to control the quality and ensure a consistent supply of constituents –Uncured prepreg properties, defects, storage, handling and out-life –Baseline cure cycle and cured laminate physical & mechanical properties Minimum requirements and options to expand the database for enhanced utility

Material characterization –Material qualification to collect data representative of the population and set initial requirements in the spec Minimum of three batches for fiber and resin dominated properties –Periodic property testing to expand the database and update the spec Increased database, which is more representative of the population Process for dealing with changes to qualified materials –Equivalency sampling for five levels of change ranging from minor to major (highest level requiring a new qualification, database and specs) Quality assurance –Supplier site qualification and SPC implementation Demonstrate compliance with PCD and training –QC test panel fabrication per an associated process spec –QC test methods and acceptance criteria per material procurement spec Packaging and shipping requirements –Identify materials and maintain control through delivery

FAA Presented by L. Ilcewicz at 8/6/02 FAA/NASA Workshop for Composite Material Control25 Composite Process Specification Guidelines for development of process specification –Primary goals to: 1) define repeatable composite fabrication processes and 2) support the control of consistent and stable materials –Composite process spec for each unique material –Allow industry freedom to pursue shared process specs Develop stable & consistent processes before material qualification –Crucial to repeatable test panel fabrication –Manufacturing scaling issues and the effects of design detail for real parts indicate a need to demonstrate producibility as part of process development

FAA Presented by L. Ilcewicz at 8/6/02 FAA/NASA Workshop for Composite Material Control27 Update on FAA Consideration of a Technical Standard Order (TSO) Updated the working draft TSO for composite prepreg –Considerations for minor to major changes –Initial shared database efforts following the AGATE protocol have benchmarked possible issues within the industry Coordination with FAA AIR-120 suggest a TSO is feasible –A TSO for composites would have more controls and requirements, i.e., different than how current TSO are viewed in the industry and FAA –Use of SAE, Mil-17 and ASTM as organizations to help define the required specs and database standards were considered essential Use of these organizations for pre-requisite approval of the data and associated specs is also under consideration –Policy, guidance and training will be needed to implement the TSO More discussion within the FAA is needed to gain acceptance

FAA Presented by L. Ilcewicz at 8/6/02 FAA/NASA Workshop for Composite Material Control28 NASA/FAA/Industry Teams for Composite Standardization Several research programs involving NASA, FAA and industry teams have worked together to accelerate standardization Advanced General Aviation Transport Experiments NASA Langley Research Center Rotorcraft Industry Technology Association National Rotorcraft Technology Center at NASA Ames Research Center Standards organizations ( Mil-Hdbk-17, SAE Committee P, ASTM D30 ) should benefit from the advances achieved in above efforts Desirable to have the DOD work with the FAA and standards organizations in future efforts NRTC/RITA GOVERNMENT ACADEMIA INDUSTRY NASA
