Aerospace Structures • Aerospace Materials & Fatigue • Aircraft Alloys & Composite Materials
In modern commercial aircraft (e.g. Boeing 787, Airbus A350), carbon-fiber reinforced polymers (CFRP) are extensively used over aluminum primarily due to their:
(A) Superior specific strength and specific stiffness (high strength-to-weight ratio)
(B) Higher electrical conductivity than copper
(C) Zero manufacturing cost
(D) Ability to melt easily for recycling
Answer Key:
A
Step-by-Step Verified Solution
