Advice needed for composite.... Hello guys. Newbie here this is my first post ;-). I am a 2nd year Eng. Mech. Univ student. An assignment for one of the credits is to design a composite material (made up of 2 materials)of rectangular section width 30mm and thickness 20mm, length 400mm. The composite must NOT include a metal material while having good strength and rigidity with low density. The component will be tested by simply supporting at each end and a heavy load strapped at midpoint (say 60kg). Deflections must be small and within elastic range. Now for the life of me excluding carbon fiber, teflon and a few other exotic materials what 2 materials and bonding method could I use to make the section strong enough?? I have access to all kind of woods and many polymers (ABS, Polycarbonate, Polyethylene...etc). Any suggestions guys? Thanks for any help!
