Without curly fabric (fabric of weaving of NCF-Non-crimp Fabrics) dispute, it is by the one-way layer of different way suture is comprised together. Because each fiber can be placed,go up in different way or axis, so it can offer intensity and stiffness on many direction.
Compare with photograph of traditional fabric form, main advantage:
- Have without drape fiber taller drawing and curve function;
- Without the ruffle straight fiber allows to good colophony is permeated and flow, relatively ideal to infuse and light qualitative RTM, and suture conduces to through face plate (Z direction) undertake colophony ooze moves, this fixes rate to be defeated the biggest change and word is extremely perfect;
- Avoid area of ply of rich colophony layer, mean the weight mark with very easy higher implementation (WF- Weight Fraction);
- But multilayer suture, this means higher deposit rate (than spreading silk automatically (AFP) , automatic shop is taken (tall) of ATL) deposit rate.
New A320” of “ of empty guest future plans every months to make 70-100 wear a plane. Want to choose to making a process so, the craft with short cycle. Wing uses “ carbon fiber not to have curly fabric (craft of ” of solidify of NCF)-RTM- blame autoclave makes: Wing (envelope, long joist, bridge) ; Flap; Faze flows board. At present empty guest has made a box of 3 portion alas experiment (see figure below) . Flap has completed a test the job. Faze flows board had built produce per month product line of 70 computer pilot automation of the portion (the trouble that automation product line makes flows board, on the A320 that can be used now) .
Note: Edit according to the data on the net.
