How pls describe
On a pre-preg composite
- life can be extended by 12 months if stored below 10 degreesC
- no life extension is allowed, it must be used immediately.
- life can be extended by 12 months if stored above 40 degreesC
Any body out there??
Answer regarding storage above 40 degree Celsius seems absurd, i don't have in depth knowledge about the subject but i searched on the web concerning this question. Below are two web links which helped me get convinced that to extend the life of pre preg composite it needs to be stored in low temperature.

Which wing increases drag when the ailerons are moved?
- Both wings increase drag but the wing with the down-going aileron increases more.
- Both wings experience an equal increase in drag.
- Both wings increase drag but the wing with the up-going aileron has more.
i think the down going wing(i.e.up going aileron) instead of down going aileron (i.e.up going wing) increases more drag
