1. Use a maul or splitting wedges to split hardwood. A splitting maul is essentially a thicker, more wedge-shaped axe made for splitting hardwood along the grain, with a blunt sledge-hammer edge on the back of the splitting blade.
Carbon fibre is a material that is made from very thin fibres having carbon atoms. These are bonded together in microscopic crystals, aligned parallel to the long axis of the fibre. It is this crystal alignment that makes carbon fibre so strong. Carbon fibre is used to make composite materials with plastics resins.
The modulus of carbon fiber is typically 33 msi (228 GPa) and its ultimate tensile strength is typically 500 ksi (3.5 Gpa). High stiffness and strength carbon fiber materials are also available through specialized heat treatment processes with much higher values.
