Polymers used in aircraft
WebTypically semi crystalline polymers such as PEEK, PEKK and PPS are used on the exterior of aircraft as a result of their inherent resistance to solvents. PEI and polycarbonates( for more cost competitive applications) are more commonly used in interiors because they are fire retardant, but not necessarily resistant to some of the harsh solvents use on aircraft … WebDec 5, 2005 · In this paper, it is argued that fiber reinforced polymers, especially carbon fiber reinforced plastics can and will in the future contribute more than 50% of the structural mass of an aircraft. However, affordability is the key to survival in aerospace manufacturing, whether civil or military, and therefore effort should be devoted to analysis ...
