Why not ask us? For instance, the report states (on page 4): "The material properties of composites make them more resistant to fatigue and corrosion than metal, which leads to lower maintenance costs." In aluminum airplanes, pressurizing a cabin at 6,000 feet would be weight-prohibitive and cause structural fatigue concerns. profitability on both short- and Could it eliminate those issues (eg rust, fatigue, weight, weakness etc) associated with other materials? This gives the airplane highly efficient lift-to-drag characteristics that reduce fuel consumption and costs. More recent NASA research has studied the aging and durability of advanced structural materials, including composites, used in aircraft. Thats about 10 times the typical vertical descent rate when a big jet lands, and three times the rate its landing gear is required to withstand. Because there are things that are new about this, weve gone way, way beyond what might have been basic requirements, Jenks said. Yates views on the composites fire threat stem from work he did in the 1970s with NASA that resulted in FAA rules effectively banning the use of epoxy-based composites from aircraft interiors because of the fire hazard. While Triac Composites does not do any work in the aviation sector, its owners have 30 years of composites' experience in the marine industry, specifically with sailing boats. This approach offers weight savings on average of 20 per cent compared to more conventional (and outdated) aluminumdesigns. The 777 floor structure is all composite and highlights the advantages of this material when applied in a harsh environment. The associated reduction in drag reduces fuel consumption. The Douglas DC3 (dating back to 1936) had a take-off weight of about 25,200 pounds with a passenger complement of about 25. All airliners entering service since 1990 comply with that ban. Composite materials have many advantages. Phone(English &Ting Vit): While a typical bonded repair may require 24 or more hours of airplane downtime, Boeing has taken advantage of the properties of composites to develop a new line of maintenance repair capability that requires less than an hour to apply.
