Fibers
Fiber or fibers is a class of material which are having continuous filaments or having discrete elongated pieces similar to the length of thread. Fibers are very important in the biology of plants and animals for holding tissue together.
1.
Fibers
can be spun into filaments or string or rope which can be used as a component
of composite material or matted into sheets so as to make the products like
paper or felt.
2.
Fibers
are often used in the manufacture of other materials.
3.
Fibers
are inorganic or organic, natural or synthetic.
4.
Synthetic
fibers can be produced very cheaply and in large amounts as compared to natural
fibers.
5.
Burlap
is a coarse jute or hemp which is a natural fiber. Hessian is a jute fabric.
Silk and cotton are produced from natural fibers.
6.
Rayon
and nylon are organic synthetic fibers. Glass wool, lead wool and asbestos are
mineral fibers of which glass wool and lead wool are synthetic fibers.
7.
Steel
fiber, carbon fiber and glass fiber are the new and recent trends used in the
construction work.
Artificial Timber
· The artificial timber is made of enhanced, modified
and thermoplastic material that is filled with wood fiber and plant fiber.
· Combining advantages of timber and plastics, the
material features in corrosion resistance, warp free, convenience in
maintenance and superficial similarity to wood etc.
· The artificial timber was invented by Shri S.G.
Kulkarni and the artificial timber is also termed to be as poly-timber or an
artificial wood. It was developed in the year 1993.
· It is the best substitute over the entire range of
natural wood, jungle wood and the exotic woods like Burma teak, sag wood.
· Since the process involves "extrusion" the
end products like squares, hexagons, angles, flats, channels, hollow sections
etc. can be produced so as to 'minimize' skilled labour.
· All mechanical processes like planning, drilling, chipping,
milling, screwing, painting, varnishing, laminating are totally eliminated in
the artificial timber.
Miscellaneous Acoustics Materials:
When
the sound intensity is more, then it gives the great trouble or nuisance to the
particular area like auditorium, cinemall hall, studio, recreation center,
entertainment hall, college reading hall. Hence it is very important to make
that area or room to be sound proof by using a suitable material called as
acoustics material. It is measured in decibles (db).
Acoustics
material play a vital role in the various area of building construction. In
studio, class room, reading hall, cinema theatre, more concentration is
required to listen, hence the acoustics treatment is provided so as to control
the outside as well as inside sound of the various building until such that
sound will be audible without any nuisance or disturbance.
Types of Acoustic Material:
1. Acoustic plaster.
3. Perforated plywood.
2. Acoustic tiles.
4. Fibrous plaster.
5. Straw board.
6. Pulp board.
7. Compressed fibre board.
8. Hair felt.
9. Cork board slabs.
10. Foam glass.
11. Asbestos cement boards.
12. Thermocoal.
13. Foam plastic.
14. Chip boards.
15. Gasket cork sheet.
16. Hair felt.
17. Acoustic foam.
