3. 1.INTRODUCTION
• Brake pads is an important part of braking system
• It generally consist of asbestos fibers along with several
other ingredients
• Asbestos cause health risk due to its carcinogenic nature
• Banana peel replace the asbestos fiber
3

4. 2.SAMPLE PREPARATION
2.1 MATERIALS/EQUIPMENT
• Banana peels
• Phenolic resin
• Engine oil
• Water
• Brake pad mould
4

5. 2.2 METHODS
• Banana peels are dried and milled at 250 rpm to form
banana powder(BUNCp).
• Powder was packed in a graphite crucible and fired
in furnace at temp. 1200c’ to form banana peel ash
(BCp).
5

6. 2.3 ANALYSIS OF PARTICLE SIZE
• Accordance with BS1377:1990
• 100gm of samples placed in set of sieves and
shaken for 15 minute
• BS.100 micro.meter used for research
2.4 PRODUCTION OF TEST SAMPLES:
• Varying phenolic resin frim 5-30wt% with interval
of 5wt%
6

7. • 2 set of samples were produced using BUNCpand BCp
• The mixture is transfered to the mould kept in a hot
platen press for 2minute

8. 3.EXPERIMENTS
3.1 DETERMINATION OF SPECIFIC GRAVITY
• Weighing the samples on a digital weighing machine
• Measure the volume by liquid displacement method
• Specific gravity is determined by dividing the unit
weight of brake pad material by unit weight of water
8

9. 3.2 WATER AND OIL SOAK TEST
• Samples were oven dried and its weight was
measured
• After 24 hours of submertion of water and oil, the
specimen is weighed
• Absorption(%)=(W1-W2)/(W2)* 100%
• W1:Weight after immersion
• W2:Weight before immersion
9

10. 3.3 DETERMINATION OF HARDNESS
• Brinell hardness tester with 1.56mm steel ball
indenter,minor force of 98.1N,major force of 981N
• Hardness value was taken after the application of
minor and major force
10

11. 3.4 DETERMINATION OF COMPRESSIVE STRENGTH
• Using Honsfield Tensometer, compressive force applied
continuously till failure
• The load at which failure occured was recorded and the
compressive strength can be found out
11

12. 3.5 DETERMINATION OF WEAR RATE
• A pin on disc test apparatus with disc of 120mm
diameter,8mm thick was used to investigate wear rate
• The weight measured before and after the test
• WEAR RATE= DW/S
• DW- Weight difference of sample before and after test
• S-Total sliding distance

13. 4.RESULT AND DISCUSSION

14. • Proper bonding was achieved with that of BUNCp at
20 weight % resin addition
• Resin addition beyond 30 weight % to BCp may result
in proper bonding
• Interfacial bondings of the formulation of BUNCp are
better than that of BCp
• Small discontinuities and a reasonably uniform
distribution of banana peel and the resin

17. ADVANTAGES
• High compressive strength
• Reduce health risk
17

18. DISADVANTAGES
• Maintenance cost is high
18

19. CONCLUSION
• Proper bonding with BUNCp at 20% resin addition
while BCp at mere 30% has not been achieved.
• Compressive strength, hardness of the samples were
seen to be increasing , while the oil soak,wear rate d
ecreased as weight percentage resin increased.
• The samples, containing 25 weight percentage resins
in BUNCp and 30 weight percentage BCp gave the
better properties in all.
• The result indicates that banana peels particles can
be effectively used as a replacement for asbestos in
brake pad manufacture.
