Density of Carbon Fiber is 1743kg/m^3 and that of Bamboo is 1160 kg/m^3.
Acrlyic, Nylon, Polycarbonate have similar density as Bamboo.
Bamboo's strength falls somewhere between fiberglass and carbon fiber
Some things to think about include ecological factors (bamboo is renewable), environmental factors (bamboo is flammable), loading factors (steel can be made ductile and its high properties are isotropic), and weight considerations (bamboo is much less dense) compared to Steel.
