I need to apply dimensional tolerances to drawings of composite parts used in aircraft interiors. These are mouldings and fabrications using cut and fold techniques. Does anyone know of any standards that could be applied ?
Does anybody manufacture a lightweight structural composite panel that allows light transmission and is compliant with the Airbus Industries specification ABD0031 Iss F for Flammability, Smoke density and toxic gas emissions.
When autoclave curing parts it is normal to vent the vacuum when pressure gets to 15 - 20 psi. Why is this ? Are there any good reasons to leave the vacuum connected ??
I don't believe conventional pressure vessel design calculations are valid for composite cylinders exposed to high hydrostatic pressures, mainly due to the tendency of the fibres to buckle under compression. How should structural analysis be approached to establish the fibre type, wall...
