What are the types of manufactured boards
Laminate boards
Compressed boards
Give some advantages of man made board to natural timber
Available in large sheets
Do not do things like warp
Consistent properties
Prefinished
Treated with resitance
Give some laminate boards
Plywood
Blockboard
Laminboard
What are the general properties of laminate boards
Thin layers of wood, ontop of eachother with the grains perpendicular, giving it a consitent structure, glued under heart , with synthetic resin
Where would laminate boards be used
Load bearing shelves,etc
What are compressed boards
Boards made from chips, strands etc of timber glued together under compressive forces
What are some compressed boards
Chip board
MDF or HDF
Give some properties of chipboard
Made from the waste
rather weak and flexible
poor durability
To better it it will have a prefinished surface venner
Give some properties of mdf and hdf
similar to chipboard, but made of finer fibres , giving a harder surface and greater stability
when choosing timebrs what should be cosnidered
grain colour and pattern
compression strength etc
sutiability for lcoation fo use
ease of machine
comemrcial aspects, stock , costs etc
what are hardwoods
timbers geenrally from slow growing trees
what are softwodos
timebrs from fast growign trees
speak abotu ply wood
thin layers of wood, glued at 90 degrees to eachother, good strength in all directiosn etc ,
flexible plywood
