Colophony radical composite material compares intensity because of its tall, design agile, damp is decreased brace up performance is outstanding wait for a characteristic, had made the important construction material of engine of new generation aviation. We will introduce colophony radical simply according to what examining a data composite material uses a case mediumly in civil aviation engine, emphasize discuss its to be in line of casing of fan lamina, fan, tone, lining and the innovation application that oppose thrust device to wait for crucial part. Fan lamina: The lamina of fan of summit summit confluence of function regards aviation as one of crucial parts of engine, many challenges were experienced in the development course in the past. However, as colophony base the ceaseless promotion of composite material function, the design of fan lamina also be able to major breakthrough. General Electric Company used colophony radical in 90 time the lamina of the fan that take energy of life of engine of composite material production GE90, came true successfully light quantify the promotion with anti-impact properties. LEAP series engine was to use 3D whole to braid a technology more, improved the performance of blade further. Collect department of • Luo Gong is newest the “ that roll out is super fan ” is more carbon fiber / tenacity colophony the fan lamina that dip expects the shop sticks solidify and becomes beforehand, decreased promotion of efficiency of heavy 700 Kg, fuel to offer a possibility for engine whole. Fan casing: The casing of innovation design fan that measures excel in gently flies in safeguard there is main effect in safety. From hard include soft included innovation design, the application of composite material is raising colophony radical include the effect while, also achieved a structure light quantify. General Electric Company uses complete composite material to make the fan casing of GEnx engine, through automation 3 axes braid 2 dimension technology, increased integral structure strength greatly. Acoustical line: Revolutionary noise reduces the eddy fan as aviation engine to compare increase ceaselessly, noise of the fan that take energy of life becomes one of main noise sources. The Acousti-Cap of company of hertz family name is lain between structure of type a honeycomb-like thing is embedded to fall for noise elimination inside the cap a confusion of voices offerred innovation solution. This one design applies successfully at how model aviation engine, came true to be as high as the noise attenuation of 30% . Lining: Be able to bear or endure the leap of lukewarm function is opposite to answer high temperature environment, colophony radical of composite material be able to bear or endure lukewarm function also got remarkable promotion. Get together acyl inferior composite material lining is in amine compressor be able to bear or endure lukewarm demand is higher the application of place, for example the Vespel series of American Du Bang company is in much model application succeeds on engine, for the high temperature of aviation engine the job offerred feasibility. Oppose thrust plant: The precursor colophony that unifinication designs base the material of composite material and structure shape at the same time the unifinication design that character is aviation engine offerred a possibility. American Nai surpasses the compositive type of the LEAP-1C engine that the company rolls out on C919 air bus to boost a system, include composite material of one form of characters or letters to enter gas commutate cover and “O of integral composite material ” to slide choose unit instead, initiated the new phase that unifinication designs. Future looks into colophony radical the composite material success on engine of civil eddy fan applied experience to provide precious reference for our country. Although be in,research and development and applied respect still exist certain difference, but as our country colophony base the ceaseless progress of composite material technology, believe prospective our country to will welcome more revolutionary development in domain of civil aviation engine. Wait for many sided hard through strengthening research and development of structural design, raw material, workmanship and evaluation of test and verify, our country becomes hopeful colophony radical the fundamental strength of domain of composite material application.
