bexrbetter Posted January 31, 2018 Author Posted January 31, 2018 In case you're wondering, I have ordered a bit of stuff and no luck so far. I am a bit worried now because it's almost Chinese New Year (Feb 16th) and the bar stands don't want to do anything leading up to then, and for about 2 weeks after. I have been caught out a few times with this situation. i am having a terrible time getting a new stock of 6061 sheet as well, I only want a Tonne this time around, but it's hard to get a factory to make less than 5 Tonne min order, especially just before Chinese New Year as mentioned.

Could be worse, you could live in a country where Ramadan is followed avidly (or live in Perth).
Marty_d Posted January 31, 2018 Posted January 31, 2018 I only want a Tonne this time around... I know people talk about the MTOW being increased, but that's a bit over the top isn't it? 1
fly_tornado Posted January 31, 2018 Posted January 31, 2018 you gotta think big if you are running an aircraft factory 1
Marty_d Posted February 1, 2018 Posted February 1, 2018 you gotta think big if you are running an aircraft factory Yeah I know, just kidding. A tonne is only 3 aircraft, 4 at the most.
bexrbetter Posted February 1, 2018 Author Posted February 1, 2018 A tonne is only 3 aircraft, 4 at the most. Prob only 2 getting things finalised with a few changes and test runs.

fly_tornado Posted February 4, 2018 Posted February 4, 2018 well *we all thought* that the kit building industry was going to get shaken up
bexrbetter Posted February 7, 2018 Author Posted February 7, 2018 Of course, a supremely confident aircraft designer and builder would order in no less than 10 tonnes Not when I'm paying for it now and someone's paying for it later and I won't have a show of getting what I spend now back. Was at the fiberglass company today picking up a piece of E Glass for testing, and noticed the high wing something that I have seen there before was being prepped ... 1

onetrack Posted February 7, 2018 Posted February 7, 2018 If you're constructing an aircraft, why are you selecting E-glass, instead of S-glass? (or R-glass as the Europeans call it?)
bexrbetter Posted February 8, 2018 Author Posted February 8, 2018 If you're constructing an aircraft, why are you selecting E-glass, instead of S-glass? (or R-glass as the Europeans call it?) Because my fiberglass guy had a roll of E glass and epoxy ready to do another customers job and I said whip me up a square so I can experiment with it. E glass is popular in China, S glass not so much. Numbers of craft have been done in Vinylester also, not that I would. Personally I would use basalt except it's one of those products tainted by myths, and you know how accepting of myths aviators are .... 2

nomadpete Posted February 8, 2018 Posted February 8, 2018 Interesting stuff, that basalt fibre. But you'd have to buy the good stuff from the Ruskys. Thanks for the prompt, Bex
onetrack Posted February 9, 2018 Posted February 9, 2018 Absolutely fascinating, that Basalt fiber. First I've known of it, and I've never run across it in use anywhere (well, not where I was told it was in use). The Russki's certainly seem to be the biggest producers of it. I often wondered what was replacing asbestos in brake pads today. Kevlar, Aramid and various other products have been mentioned, but no-one has ever mentioned Basalt, which shows great potential in that application. The fire resistance of Basalt would be a great advantage in aircraft applications.

onetrack Posted February 9, 2018 Posted February 9, 2018 it's the resins that burn Yes, agreed. But having fiber reinforcement that resists melting for an extended period, makes for overall superior fire resistance to fiberglass. "A common use (for Basalt fiber) is in the fire protection sector because of its high melt-point. Fire-blocking tests performed by Basaltex placed its basalt fabric in front of a Bunsen burner, placing the yellow tip of the flame in direct contact with the fabric. The yellow tip reaches temperatures of 1100°C to 1200°C (2012°F to 2192°F) and causes the fabric to become red hot, similar to a metal fabric. When exposed to the flame, basalt fiber maintains its physical integrity for extended periods of times, but the company found that a fabric made of E-glass with the same density can be pierced by the flame in a matter of seconds." Basalt Fibers: Alternative To Glass?
bexrbetter Posted February 9, 2018 Author Posted February 9, 2018 The issue with basalt, which is lava, is it can have discrepancies in fiber size and is hard for the manufacturer to grade with consistency. Most strands are almost as good as Carbon Fiber at a fraction of the price, while the weaker strands are down near E glass, so the 'weakest link in the chain' comes into play, in truth it depends on the supplier, the layup, and in what application. Likely for those reasons you will never see it used at Airbus or Boeing. It is certainly an alternate to S Glass for most applications though. If you made a plane from it then you would get the scare monger experts jumping in to tell everyone how they are going to crash into a kindergarten if you use it, I've seen exactly that already. China has plenty by the way, there's a large factory nearby in Chengdu. Sichuan Aerospace Tuoxin Basalt Industrial Co., LTD 2 1
ClintonB Posted April 6, 2018 Posted April 6, 2018 Is the project still going Bex?. I was keenly following your progress. Cheers
bexrbetter Posted April 7, 2018 Author Posted April 7, 2018 All is very good, can't talk about it in public, will be back into it soon.
