This document presents research on the effect of nano-silica mixed polymer coating on fiber reinforced polymer (FRP) composites and their bonding with concrete. The research involved manufacturing FRP composites using glass fibers and resin, coating samples with mixtures of nano and micro silica, and testing the samples to analyze the effect on bending strength and tensile strength. Testing results showed that micro silica coatings decreased strength as concentration increased, while nano silica coatings increased strength as concentration increased. The research concluded that nano silica coatings improve the mechanical properties of FRP composites.

6. INTRODUCTION
 Fibre-reinforced plastic (FRP) (also known as fibre-reinforced polymer) is a composite material
made of a polymer matrix reinforced with fibres. Composites are established as an alternative
material system to traditional materials such as steel, wood, aluminium and concrete.
 FRPs are commonly used in the aerospace, automotive, marine, and construction industries.

12. MANUFACTURING PROCESS
PULTRUSION METHOD
• In this method a strand of fibres is passing
through the guided pulley and also pulled
into the resin bath where fibre and resin
both are mixed well, then which are
further consolidated in a heating device.
It is passes through constant cross section
with long in length.
• It is a continuous process and the
production cost is also low.

14. TESTING
• Material testing is done on the following two
basis;
1) Bending Strength
2) Ultimate Tensile Strength
Both test is done on the UTM (Universal Testing
Machine) and tested specimen is shown in figure.

21. CONCLUSION
Based on the results of experiments performed on FRP
composites the following conclusions can be drawn:
As we increases the micro silica content in coating of FRP composites
the bending strength of FRP composites get decreases.
As we increases the micro silica content in coating of FRP composites
the ultimate tensile strength of FRP composites get decreases.
As we increases the nano silica content in coating of FRP composites
the bending strength of FRP composites get increases.
As we increases the nano silica content in coating of FRP composites
the ultimate tensile strength of FRP composites get increases.
