INTRODUCTION

• In order to save our mother earth from its destruction we have created an alternate material for timber; this could overcome the cutting of trees and uprooting of trees and which would help us to conserve our wild life and natural resources.

OBJECTIVES

• There is an urgent need to conserve our environment which is destructed by cutting of trees for the manufacture of timber products; it is an urgent necessity to create an alternate that could overcome the environmental cycle and as well as the requirements of timber.

ALTERNATE MATERIALS

• Alternate materials are the waste materials that are obtained from the bark of the beetle nut trees which are abundantly available; these barks are obtained from the trees by removing the upper layer of the tree(ie BARK) without causing any damage to the tree so that these trees can produce number of layers during their life time which can be used as an alternative to replacement of timbers.

REQUIRED CHARATERISTICS OF ALTERNATE MATERIAL

• The alternate materials (I.e. Beetle nut bark) should fulfill the following characteristics

• The alternate materials should overcome the various kind of stresses applied on it

• In case this materials are created they should withstand against the corrosion and varied climatic conditions

• These materials should be effective, simple, environmentally computable and cost effective

COMPOSITE PREPERATION

• The beetle nut bark is the natural resource and bio degradable and it also serve as an effective replacement for the plastic material available in the market today. The alternate materials are made from the natural resources and environmental friendly.

The preparation of the alternate material

involves the following steps

• The barks of the trees are removed very carefully so that the barks are not damaged

• The removed bark is then immersed in water for a period of 30secs and then removed

• The soaked barks are then dried in the sunlight so that these barks are now free from dusts and other impurities

• And this was then dipped in a solution of 2% detergent and dried again to clean the surface and to kill the germs

• These barks are then cutted in to a square shape of 30*30cm

• These cutted sheets are then placed in the compression machine and loaded to 200KN so that these barks will become flat and it is easy to work with this compressed barks

• Now each layer is placed one above the other to make it as an single layer where in between each layer an adhesive(for example: FEVICOL) is added

• About 11layers are placed or arranged to form a single material. Then this material is placed in the compression machine and given a load of 300KN for about an hour

• This material is removed from the machine and then it is kept in sunlight to dry the moisture present in the adhesive so that each layer will bound together with high strength

• Now the materials get good strength against the compression and tension and it is also capable of withstanding varied humid conditions

• The beetle nut barks are now capable of withstanding heavy loads and stresses but they are poor resistant to water as they have huge pores and they allow the water to percolate in to them and this reduces the strength of the material that we prepared

• On conclusion we can solve this problem by the following method– The alternate material that we prepared is given an

additional coating of plastic which is recycled from the waste plastic collected from the garbage’s

– By making an layer with damp proofing agents also

• After this are coated with plastic these materials are now with no porous and it also gains strength and corrosion action of the cold climatic conditions

• Now these materials that are coated with plastic can also be used as an doors, partitions and other purposes and this can also be coated with multi colour paints to make it attractive too.

TESTING PROCEDURE

• The materials that we prepared is allowed to pass through the various kinds of tests

• At first the test, specimen dimensions are noted and then exposed to the sunlight for 12hr and after removing the of the specimen it is noted there should be no change in their dimensions.

• Now the specimen is checked for its load bearing capacity by placing the specimen over UTM and tested for compression up to the load of 350KN it was observed that there was no change in dimensions up to 350KN compounding.

• And the specimen is tested for its tension. At the load of 200KN the specimen is elongated and broken out. Below that load was there no deformation in the body.

• The specimen was were immersed in the water for 24hr’s and after removing it from water the following observations made.

• Dispersion of the layers.• Swelling of the barks.• Changes in dimensions.

ECONOMICAL AND ECO FREINDLY

• The barks that are obtained from the trees are very less expensive.

• The plastic that are used for the coating is the recycled plastic and hence a huge plastic can be recycled instead of dumping it in to the earth.

• The most timber products that are prepared comes out of the cutting of trees but this would not undergo any process that leads to the destruction of the environment.

• They react less to the environment and they have very long life time.

• After the plastic is coated paints can be used to draw an art over the material so that this would lead to be more decorative with less cost .

• This can be easily disposed in to the environment as this are eco friendly organic materials.

CONCLUSION

The ultimate aim of these alternate materials is to replace good quality of timber without cutting of trees. The timber now used all over the world is drawn by cutting the various kinds of trees which is collapsing the environmental cycle. Thus an effective replacement for the timber is the beetle bark timber which is 100% made by undistrubing the environment.
