Municipal engineering water supply pipeline interface of Carbon
Fiber Profiles glass fiber.
USES structure and characteristics
Carbon fiber profile is a kind of high strength and modulus of high
temperature resistant fiber, high-end
varieties for chemical fiber.Because carbon fiber is light and
hard, so its application is very extensive.
Made of carbon fiber profile reinforced plastic light texture, high
temperature resistant, radiation protection,
water resistance, corrosion resistance, is manufacture of aircraft,
weapons and corrosion resistant
equipment excellent material.
In recent years, carbon fiber is widely used in large aircraft,
such as the A350 and A380 airbus, Boeing
787 using carbon fiber composite materials to reduce fuel
Another large wind turbine blade, the car, vehicle body, are an
important factor of carbon fiber composite
materials demand increase.Bicycle use carbon fiber composite
material as the frame, but because of
carbon fiber composite materials manufacturing cost is high, more
than for the higher-order type to use.
Applied in engineering
Commonly used in civil engineering material with cement, sand,
steel, wood, brick, etc., in which the
combination of concrete and reinforcement is considered to be the
most widely used structural materials.
But as the growth of the structure service time, more and more
problems are exposed, the representative
of which is reflected by the emergence of "crisis" of concrete in
the 1980 s of the durability of the concrete.
The application of steel structure also has a certain proportion,
it overcome the weakness of their heavy
concrete structure, but in the use of yield in the high temperature
and brittle fracture in the earthquake,
the representative of which is the United States "9 · 11" incident
and the hanshin earthquake in Japan.Get
a rapid development of materials science in the 20th century, the
fiber composite material was applied in
civil engineering, glass fiber reinforced plastic is the most
widely used in it.The application of this kind of
material to make the structure of civil engineering, functional
diversity, flexible but lower modulus of glass
fiber reinforced plastic, limits its application as a structural
material in civil engineering.
Carbon fiber than high strength and modulus ratio, and 10 times
respectively steel more than 5 times;At
the same time it also has excellent electric and magnetic
resistance, high temperature resistant
performance and resistance to chemical attack, is considered the
best comprehensive properties of
advanced materials, so its application in various fields to promote
very quickly.The application of carbon
fiber flexible and varied in form, which can use the long fiber as
structure material, and use the short
fibers as functional materials;(2) substrate but resin and can be
cement;(3) with the matrix of composite
material can be placed in the component appearance but also in
internal components;(4) can be used
independently and can be blended with other fibers used;5. The
composite material is anisotropic material,
thus can change performance in all directions, especially the
material can be designed into expansion
coefficient is zero.Carbon fiber in many aspects in civil
engineering can take advantage of its performance.
(2) the application status of carbon fiber in civil engineeringThe
carbon fiber mainly structural materials
and functional materials in two forms used in civil
engineering,including most used as structural materials.
High dielectric strength
