FiberBoard: Classifications and Properties
Fiberboard for materials Study
Introduction to the Topic
What is the definition of fiberboard? Fiberboard is a core topic in material engineering and science. According to International Standard Organization, fiberboard is defined as sheet material generally not exceeding more than 1.5 millimeters in thickness manufactured from ligocellulosic fibers with the primary bond from intercepting of the fibers and their inherent adhesive properties. Note that bonding materials can be added before you achieve a material called fiber. This topic is written because of its vitality to material engineering, which is one of the areas of specialization in engineering faculty. Students of metallurgical and materials engineering offer this topic before their graduation from any institution of their study. Food and Agricultural Organization defined fiberboard as broad generic term encompassing sheet materials of widely used densities manufactured from refined or partially refined wood fibers or other vegetable fibers. Fiberboard has classifications and each of these classifications has their applications and properties. All these will be discussed.
Classification of Fiberboard
Classifications and properties of Fiberboard
Fiberboard as an important and great material has criteria for its classification which is based on:
- Source of raw material;
- Method of sheet formation; and
- Type of place to be used.
Classification of Fiberboard Based on Density or Specific Gravity
You have to be observant when dealing on this category of classification in order not to get confused in any way. International Standard Organization has their explanation on this classification as well as Food and Agricultural Organization does. International Standard Organization classified fiberboard on its density as follows:
- Soft fiberboard: This is a fiberboard that has density of less than or equal to 0. 35 gram per centimeter cube.
- Medium fiberboard: It has density greater than 0. 35 but less than or equal to 0. 80 gram per centimeter cube.
- Hard fiberboard: This has density greater than 0. 8 gram per centimeter cube.
Under the same classification based on density, Food and Agricultural Organization also has their own classification. They classified it as:
- Non-Compressed fiberboard: This category is broken down to two other headings as semi rigid and rigid insulation fiberboard. Semi rigid fiberboard have density range of 0. 02 to 0. 15 gram per centimeter cube. Rigid insulation fiberboard has density range of 0. 15 to 0. 40 gram per centimeter cube. You have to be careful with these classification and explanation in order not to interchange these data. Once you make mistake on these data, you make a mess of the whole thing. So, care must be taking when studying this topic.
Classification of Fiberboard Based on Source of Raw Materials
Interest on this categorization is centered on the type of material that is used in formation of fiberboard. Interest is not paid on the density, specific gravity, method of formation or on the kind of environment on which the fiberboard is to be used. Hence, the classification has it thus:
- Bagasse fiberboard;
- Fiberboard from bamboo;
- Melina fiberboard;
- Those from recycled furniture material; and
- Fiberboard from forest tress.
Classification of Fiberboard Based on Method of Sheet Formation
This classification method has all the interest focused on the processes that result to its production. You do not pay interest on any other thing but only on the processes that result to formation of the fiberboard. The sub grouping under this classification is as follow:
- Wet form fiberboard: When you see this type of fiberboard, one face is smooth and the other face is rough. This type of fiberboard has purpose it is made for and not for all purposes.
- Dry form fiberboard: This type of fiberboard has both faces rough.
Classification of Fiberboard Based on Place to be Used
These types of fiberboard have selective places where they can be used. The kind of fiberboard you used in the internal part of building is not the same with one used on the external. When you are to build your own house where you are to live, be careful so that the workman does not use the fiberboard that is to be positioned internally for external use. Classification of fiberboard based on place to be used includes:
- All weather fiberboard: You do not need a native doctor to tell you the meaning of this kind of board. This is because it self-explanatory from the name given to it. All weather simply implies everywhere. Any fiberboard bearing this name is produced for both indoor and outdoor use. It can be used on internal part of a sitting room as well as on the outer part.
- Exterior fiberboard: It is made for inner use only. When this fiberboard is used internally, it does not give the required result expected from it.
- Interior fiberboard: This fiberboard is manufactured for inside use and it damages easily when it is used externally. Rainfall can spoil it when it is used for outdoor purposes.
Properties of Fiberboard
- Fiberboard has isotropic properties. It means that property of fiberboard is dependent on direction of test.
- It has high specific strength.
- The property of fiberboard is influenced by density of weight of the pulp.
- It has good nailing and gluing ability. In other words, it can easily hold nails.
- You can enhance its resistance property to bio-degradation by adding preservatives.
Fiberboard is a material which is professional made by the Materials engineers. The thickness, nature and size of fibreboards are dependent on their applications. Fiberboard is explained on this piece of write-up. The two principal definitions came from International Standard Organizations and Food and Agricultural Organization. This piece detailed out the properties and classifications of fiberboard.
