rodgerc Posted Sunday at 09:33 AM Posted Sunday at 09:33 AM Can you believe that poor bloke from Canada wants to spend time on his holiday interacting with the likes of us 😳 Maybe he’ll opt for a Rhine River cruise instead. 😜 3

Where else is he going to learn that Rotax engines are badly designed Or get legal advice about car racing. We have it all ,😂 4
Moneybox Posted Sunday at 02:59 PM Posted Sunday at 02:59 PM (edited) I apologise for keeping this alive but the printed part may be very useful as mould for chemically set plastics such as Kevlar, carbon fibre or fibreglass. Edited Sunday at 03:00 PM by Moneybox 2 2 1

Agreed. You could actually lay up on it, and just let it become part of the structure. 1 1

It could collapse and block the interior. Usual Procedure is to use a material which can be melted or collapsed inside the Carbon Fibre etc structure and extracted.

Usual Procedure is to use a material which can be melted or collapsed inside the Carbon Fibre etc structure and extracted. If you've seen how course something like a pla print is, you'd see the resin will permanently bond to it. But if course you can do the other way and lay up INSIDE the print.

Nev Agree, some should be made of aluminium of steel. Where light weight is required mig welded aluminium tube can be fast to produce and strong. Light steel tube welded or with Nickel Bronze brazing are also usually lighter than castings and both fire-proof. 3 1

I'm pretty sure I've seen fibreglass (GRP) shrouds etc in engine bays. They are combustible. But would probably burn slowly, could be why fibreglass is allowed? 1

turboplanner Posted Tuesday at 02:36 AM Posted Tuesday at 02:36 AM FRP is Fibreglass Reinforced Plastic i.e. a plastic reinforced by glass. There are many types of glass and many types of plastic. Fire retardant resins are used on critical applications, and I've seen it used on Shell Petrol tankers successfully in Australia. Shell agreed to it after seeing a Tanker on fire containing the boiling surface of the petrol, so not like the old FRB boat. 1
facthunter Posted Tuesday at 02:49 AM Posted Tuesday at 02:49 AM And Burned carbon fibre is really hazardous.. Even small oil leaks are a big fire risk and oil mixed with Dust More so. Nev.

onetrack Posted yesterday at 02:55 AM Posted yesterday at 02:55 AM It's a composite Airbus A350. Interestingly, all on board the Airbus survived - the fire only took hold slowly (due to design) and this enabled full evacuation. 2024 Haneda Airport runway collision - Wikipedia EN.WIKIPEDIA.ORG 1

Boeing B787 Dreamliner and Airbus A350 aircraft both feature a large percentage of flammable carbon fibre composite in their FAA/EASA certified aircraft….As do many modern type certificated GA and ASTM conforming LSA lighties. 1 1
onetrack Posted yesterday at 04:27 AM Posted yesterday at 04:27 AM And there is a major difference between the ordinary fibreglass of the everyday kit build aircraft and the certified composite materials. Even the interior, non-load-bearing plastics inside the cabins of commercial aircraft must undergo extensive testing in relation to burn rate, heat release, smoke, and toxicity, under FAA rules. Plus, they must also meet durability tests as regards wear and tear. 2
facthunter Posted 8 hours ago Posted 8 hours ago In earlier days the Interiors had flame overs where People died from the toxicity as well as the Flammability of the Interior materials. You also often could not see. There were TACTILE indicators for the cabin crew to Feel where they were. Nev 1
