Wood is fiberous with fibres running along the length of the trunk.
55% of the tree is cellulose
28% Lignin resin
Timber is a natural fibre reinforced polymer
Proccessing Timber
1) Harvesting - cutting down
2) Coversion - cutting the trunk & branches into boards. Slab or quarter sawn
3) Seasoning - reducing moisture content of the timber
4) Board Preparation - Sawing to size
Quarter Sawn Timber
Used for hardwoods.
A lot of waste, very stable, less liable to warp and twist. Has little shrinkage because of short annual rings.
Slab Sawn Timber
Timber shrinks most along the annual ring. The longer the annual rings, the more shrinkage.
