3. INTRODUCTION
FRP materials were developed in early 1940s for military and aerospace
applications.
FRP bars are known as alternative to eliminate the corrosion problem.
FRP is a sustainable material.
7times stronger than steel.
FRP is light weight & has excellent corrosion resistance.
6. Resins(Matrix)
Primary Function:-
To transfer stress between Reinforcing fibers and to protect them
from mechanical and environmental damage.
Types:-
(a) Thermoplastic:
1) Solid at room temperature (Recycled plastic pellets)
(b) Thermoset:
1) Most common for structural uses
2) Liquid state at room temperature
7. Common Thermoset Resin Types
Epoxy resin
1)Epoxies have high strength, good dimensional stability, relatively good
high-temperature properties
2)Commonly used in aerospace applications.
Vinyl ester resin
1)Very high chemical resistance
2)Highest cost than polyesters
3)It reduced moisture absorption and shrinkage as compared with polyesters
Polyester resin
1)Lowest Cost
2)Numerous specific types of polyesters are available for use
3)Easy to use
9. GLASS FIBER REINFORCED POLYMER BARS (GFRP)
Consists of thermosetting resins & glass fiber
High strength , Light-weight, durability
Most commonly used
10. CARBON FIBRE REINFORCED POLYMER (CFRP)
Carbon fiber bars have a high modulus of elasticity, 200-800 Gpa
Carbon fiber bars are more expansive than glass fibers bars
Carbon fiber are more brittle.
11. ARAMID FIBRE REINFORCED POLYMER (AFRP)
It is an aromatic polyamid that is a man-made organic fiber for composite
reinforcement.
Aramid fibers offer good mechanical properties at a low density with the added
advantage of toughness or damage/impact resistance.
12. BASALT FIBRE REINFORCED POLYMER (BFRP)
The basalt fiber used in this study was manufactured in Russia and exhibited the tensile
strength of 1000 Mpa
A basalt FRP bar is a composite material consisting of rigid polymer resin bounding
unidirectional basalt fibers
13. TYPES OF SURFACE DEDORMATION
EXTERNAL SURFACE
a) Ribbed
b) Sand Coated
c) Wrapped and Sand Coated
d) Deformed
e) Helically Wrapped
f) Grooved
g) Hollow Core
h) Carved
14. FRP BAR SHAPES
Straight Bars
Bent Bars
Spirals
Twisted Strands
16. CONCLUSION
FRP is seeing a huge surge in usage due to it being lightweight but incredibly strong.
Entire life cycle economic with compared to traditional but it has more benefits.
FRP bars are corrosion resistance.
