Here come the Titanium ships. Finally a reason to use different materials. My only problem so far is you have carbon fiber weaker than base carbon and even plastic. Carbon fiber should be a light voxel stronger than it's base raw and certainly stronger than plastic. Carbon fiber being a construction product material should be focused as a material for ship building as a lightweight strong material with mid range resists. Since carbon fiber has a streangth to weight greater than steel, it should fall in line as such.
