Thick isn't the same thing as mass. You can be thicker but the material is less dense therefore small mass. Thickness is related to length and volume, and is increased when I see spacenoid females. If you're making a space colony, it'd be ideal to have a material that's tough but less dense so you can have most bang for your buck in mass. That way it contributes more structural strength while being less of a burden.
