Abstract
A comparison of 4 different materials for immediate app l i cation
to aircraft primary structures was made on the
basis of load-to-buckle/cost/mass. The materials tested
were: Al-2024 T3 (Alclad) , glass fibre cloth, carbon
fibre and asbestos fibre (Noramite) composites. A m a t h e matical
formulation of the problem was used which was
found to give very satisfactory res ults. This method
made use of beam vibration modes and the Rayleigh-Ritz
energy formulation and it was found that even with onl\
4 modes of vibration, the results agreed very well with
the computer analysis. A working equation lor the design
of composite panels in shear is also given.
