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 structure of coir fibre cells is narrow and hollow, with thick walls made of cellulose. Mature coir fibres contain more lignin, a complex woody chemical, but less cellulose than fibres such as flax or cotton. This makes coir much stronger, although more coarse and less flexible.
