Armor in composite material
REINFORCEMENTS IN COMPOSITE MATERIALS are reinforcements made of non-metallic fiberglass, basalt, carbon, or aramid bars impregnated with polymerized thermosetting or thermoplastic binders
The development of composite fittings began after World War II. The advantages of high durability and ease of use of composite materials have been widely recognized in the aerospace industry. However, it was not until the 1960s that research studies began using composite reinforcement to strengthen concrete structures.
One of the reasons for this interest was the need to exploit structures in aggressive environments, where concrete with metal reinforcement proved ineffective due to corrosion. Additionally, some medical centers and research institutes needed buildings with dielectric properties.
The advantages of GFRP armor
HIGH RESISTENCE
The tensile strength is
2.5 to 3 times that of a
equivalent diameter.
RESISTENCE
CORROSION
It is corrosion resistant. This simplifies storage and increases the life of the concrete.
CHEAPER
Savings of up to 30% on replacing steel reinforcement with composite reinforcement.
CHEMICAL RESISTANCE
It is resistant to aggressive environments.
THERMAL STABILITY
It does not change its characteristics
in the range from -70 C ° to
+100°C.
HIGH DURABILITY
Its high durability
extends the life of the structures 2-3 times (50-80
years).
TRANSPARENCY
RADIO
It does not create a wave shield
radio, mobile communications and
Wifi.
LOW CONDUCTIVITY
THERMAL
Significantly reduces the
heat loss.
REDUCED WEIGHT
Its weight is 4 times less
to the weight of the steel reinforcements.
DIELECTRIC
It does not conduct electricity, it is
safe and is not magnetized
TRANSPORT CONVENIENCE
Its lightness makes the
easy and economical transport
