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.
Carbon-fiber-reinforced polymers are composite materials. In this case the composite consists of two parts: a matrix and a reinforcement. In CFRP the reinforcement is carbon fiber, which provides the strength. The matrix is usually a polymer resin, such as epoxy, to bind the reinforcements together.
