... Much of the HSR data currently exists in an spreadsheet file on a few personal computers.1 In addition, large amounts of data funded through government contracts are under the proprietary control of technology development companies. Currently, there is no easy way for modelers to know what data exist or to access the data for modeling verification.2 This is true for researchers inside these government programs as well as researchers in industries other than aerospace or those engaged in purely academic pursuits.

... and their extreme environments; · Establish real temperature limits for material systems; · Select master pedigree composite materials (resin and fiber) ; · Identify anticipated damage mechanisms; · Establish security criteria that would respect export controls and proprietary databases; · Establish a standardized list of critical material properties; · Coordinate the critical properties list with the national testing standards of ASTM subcommittee D-30; · Identify sources of reliable data, assuring its pedigree and suitability; · Coordinate government and commercial activities to increase database acceptance and use; · Provide feedback loops to end users to assure database accuracy and relevance; · Organize and coordinate roadmapping and database workshops with national societies at their venues; · Estimate the costs of database development and maintenance; · Develop strategies for funding database upkeep through user fees, dues to a newly created oversight organization, or coordination with an existing national PMC working organization; and · Ensure that experts in the appropriate disciplines participate in all of these activities.

... The model can be further calibrated using a series of specialized tests that are model dependent. PMC PHASE III ACTIVITIES A mechanism to fund curators and informaticists to collect, verify, evaluate, maintain, update, warehouse, and distribute such database concepts will also be needed.

... 44 GOING TO EXTREMES FIGURE 6-1 The Boeing 787 as designed will utilize composite materials and new manufacturing techniques, including building full barrel fuselage sections with integrated stringers, as shown here. This application of composite materials could result in fewer parts and improved aerodynamic performance and fuel efficiency.
