OBJECTIVE
The project aims at replacement of the existing roofing
materials by natural fibre composite materials.
To reduce the environmental degradation by using natural
fibre composite materials.
Aims at the fabrication of economical and light weight
roofing materials.
PROBLEM IDENTIFICATION
Materials like slate, tiles seems to be heavy and costly.
Metals like aluminium, steel, copper, are highly
expensive.
The high thermal conductivity of metals posses a major
problem while roofing.
Materials like asbestos posses a great threat to human
life.
The non biodegradability of these materials are of
great concern.
Plastics have only moderate resistance to environmental degradation (especially that caused by the photo-chemical effects of sunlight).
METHODOLOGY
The banana fibre which is already treated with NaOH to
remove the moisture is cut into small pieces and is mixed
with epoxy resin to form a mixture.
The mould for the roofing material is made.
The prepared mixture is applied over the mould to the
required thickness.
It is then placed at room temperature for solidification.
