Acoustic linings made from composite materials are used in what section of the engine?
- Not used to suppress noise.
- Hot section and Cold Section.
- Cold section only.
Explanation from PART66Online
Composite acoustic linings are fitted in the cold (fan, intake and bypass) sections, where temperatures are low enough for the bonded honeycomb materials to survive while absorbing fan noise. The hot section's high temperatures would damage composite linings, so they are not used there.
