The National Centre for Advanced Materials Performance (NCAMP) at Wichita State University's National Institute for Aviation Research has released the composite material property data and statistical analysis reports, along with the material and process specifications for Hexcel Hexply 8552 prepregs.
According to NCAMP, the lamina and laminate material property data have been generated with FAA oversight and in accordance with the requirements of NCAMP Standard Operating Procedure NSP 100. The test panels, test specimens and test setups have been conformed by the FAA, and the testing has been witnessed by the FAA. The statistical analysis reports have been generated in accordance with the procedures in Composite Material Handbook 17 (CMH-17) Revision G.
Hexcel explain the program was sponsored by NASA Langley Research Centre, and the FAA has provided the necessary oversight to ensure compliance with applicable regulatory requirements. Hexcel say they donated all the materials for the program, and Cessn fabricated over 500 test panels for the baseline qualification and allowables program.
They say the companies that have participated in the equivalency programs are Hawker Beechcraft, Spirit AeroSystems, ATK Space Systems, Boeing Helicopters, Goodrich Aerostructures, Israel Aircraft Industries, Gulfstream Aerospace, Northrop Grumman, Bell Helicopter and Lockheed Martin Aeronautics.
These Hexcel 8552 documents are the first set of qualifications completed by NCAMP and they will be submitting the data and documents to CMH-17 (CMH-17) and Society of Automotive Engineers for further publications.
Solvay has signed a ten-year agreement for the supply of composites and adhesives to be used across Bell's military and commercial rotorcraft programmes, including the Bell 429, 407, 505, 525, V-22, and UH-1.
SGL Carbon and Fraunhofer IGCV have officially opened the Fibre Placement Centre (FPC) at SGL's site in Meitingen, Germany. Compositence, BA Composites and the Chair for Carbon Composites at the Technical University of Munich have also joined the alliance, and Coriolis Group and Cevotec are planning to come on board as partners.
Fibrelite reports that since the start of its partnership with Trenwa more than 100 precast trench systems integrating Fibrelite composite covers have been sold for use in electrical substations, wastewater treatment plants, chemical refineries and many other applications across North America.
