construction of aluminium and carbon masts

[Lourencosampaio]

Hello all,

I am doing an investigation on: 'Development of materials in masts of racing triangular-rigged sailboats and how it has affected performance.'

I am looking for info about the construction of aluminium and carbon masts, and its advantages and disadvantages.

could anyone help me please?

alu is extruded. carbon can be wound out of filaments, or made with hand lay up methods. wet lay ups as well as prepreg.
do a search with those terms ;) search youtube(how its made had a part about it..) contact supplyers(selden, prince fibre tech, etc.)
