composite-arf......querry
 

Hi all,

I have a querry about the material used to build the jet fuselages by manufacturers like www.composite-arf.com or www.asiascalerc.com

what does ARF stand for ?..is it (aramid reinforced fibre ) or normal Fibre Glass ?

Most of the composite aircraft are standard fiberglass and epoxy resin. Carbon fiber is used in areas where extra strength is required and in the flying surfaces, a sandwich of fiberglass and foam is used for greater strength-to-weight ratio. I'm not sure if manufacturers use fibers like Kevlar (actually a para-aramid) in their layups for aircraft parts - except fuel tanks and I think the greatest benefit in fuel tanks is that it looks cool...

Bob,

BVM has been using Kevlar in their layups, to add stiffness in critical areas, for many years.

Thanks a lot guys...;) that solved my query.
I had been to the anual aeromodellars meet in India 2 days back & there I got to see these jets ...wow!..they all were amazing flying at 350kmph. I also saw an unfortunate Bobcat jet crash which was flying low to the runway when it just rammed into the ground due to the rear wing breaking off in mid-flight ...& the debrie was all over the runway. The turbine engine was smashed flat on one side[&o]..it was sad to see that happen....but thts part of the game & Jets are way too Kool!!..:D
