On August 1, business flying Guan Wei announces, c919 of homebred big airlines is finished obtain evidence test-fly, the distance announces to finish all test-fly task to was less than 10 days in the past only before this. This test-fly succeeds, also mean, c919 delivery operation already was entered time.

The orgnaization points out, if C919 is in by 2022 open consign, greet hopeful one billion two hundred and fifteen million seven hundred and fifty-two thousand one hundred and ninety-two markets. Forecast according to Shang Fei, to 2040 plane team dimensions will achieve 9957, hold proportion 22% , make market of big onefold aviation. Did not come to 9084 20 years to will receive civil aviaton plane, value of market total prices exceeds 9 trillion money. Among them, many new material shine brilliantly in C919 application, include alloy of the 3rd acting aluminous lithium second large-scale at civilian machine applying, composite material of T800 carbon fiber second in home use in civilian machine etc, and the industrial catenary related to this or will be benefited accordingly. In aerospace domain, have the view of ” of material of “ generation plane, generation, the application of new material is one of main impetus that aviation technology develops and progress. Will tell normally, place of civil big airlines uses main material includes alloy of aluminium alloy, composite material, titanium, high strenth steel to wait. And the scale of new material application of C919 is prep above more to mark type Boeing 737, empty guest 320, a variety of new material are more large-scale application at civilian machine On C919 application, composite material also makes one of decisive material, its application was achieved 12% , among them the majority is carbon fiber / epoxy resin composite material; Applied place includes alula of tip of stabilizer, perpendicular empennage, wing, hind the many keys place such as airframe. In addition, the production of C919 also is our country second so large-scale composite material is used on civilian machine, also be home at the same time second composite material of carbon fiber of T800 class excel in is used on civilian machine. The orgnaization points out, predicting C919 will take the coming year all demand of 300 tons of composite material, among them, will achieve to the demand of carbon fiber of class of native land T800 year all 100 tons. China trade negotiable securities expresses, current, c919 obtains evidence the composite material great majority that machine place uses is an entrance, predict to be in obtain evidence the course changes open mainland after finishing. Guang Wei of manufacturer of domestic carbon fiber is share of god of answer material, constant, medium answer god eagle all is on different level spread out collaboration with Shang Fei and downstream component manufacturer. Material of Guang Wei answer participates in the attestation of PCD comfortable boat of C919, obtain approve beforehand. At present in the light of the application of CR929 material prepares afoot; Selected business flies to boat Gao Ke in sole supplier of tool bag of the airframe before CR929.
