Material Research: Wood & Paper Products

Guide explaining the different types of materials and manufacturers.

Wood

Wood is a natural, biodegradable product. It can be used in many ways and the material itself is also flexible - steaming and lamination can be used to bend wood. Wood is generally divided into 3 categories:

  • Softwoods - from conifers (trees with needles), this tends to be strong and is commonly used in building, particularly for sections exposed to the elements since it is generally resistant to rot and insects
  • Hardwoods - from deciduous trees (flat leaves) as well as bamboo and palm, this type has distinctive grains that are aesthetically appealing
  • Engineered wood - not naturally occurring but rather manufactured, this includes MDF, composite boards, and plywood, typically treated with chemical or heat processes

For further information on different types of woods and their uses, see Builderology.

Properties:

  • acoustic dampener
  • hygroscopic (absorbs water)
  • anistropic (i.e. can have different properties in different directions)
  • burns easily
  • decent heat insulator
  • made of cellulose, lignin, and hemicellulose

Paper

Paper has been in use since Egyptians first made paper with papyrus in roughly 3000 B.C.E. It is created by breaking down a plant (nowadays, typically trees) to release fibers that are mixed with water to create a pulp and then dried.

Lower-grades of manufactured paper are made using what is called the "groundwood process" - originally, this involved using huge stones to grind up logs but now machines are used. The Kraft process is used to create strong paper by boiling plant materials in alkalis.
