The three major advantages
Small thermal expansion coefficient, the vast majority of the thermal expansion coefficient of carbon fiber
itself, indoor negative (0.5 ~ 1.6) x 10-6 / K to zero during 200 ~ 400 , in less than 10-1000 for
1.5 x 6 / K.Composite material made of it nature is stable, expansion coefficient can be used as a
standard measure.Outstanding damping with excellent through sonar using this two characteristics can
be used as structure materials, such as submarine sonar dome, etc.
Good abrasion resistance, carbon fiber and metal grinding, rarely wear, made from carbon fiber to replace
asbestos advanced friction materials, has been as planes and cars brake pad material.
Carbon fiber for high temperature performance is good, the performance is very stable under 400 ,
even at 1000 is still no too big change.Composite material high temperature resistant performance
mainly depends on the heat resistance of matrix, and the resin matrix composite materials Feeding its
long-term heat resistant up to 300 or so, only ceramic base, carbon and metal based composite
material high temperature resistant performance can be matched with carbon fiber itself.So the carbon
fiber composite material as the high temperature resistant material widely used in aerospace industry.
High X-ray transmission rate: the characteristic has been applied in the medical equipment.
Chemical properties:
Good: chemical corrosion resistance can be seen from the composition of carbon fiber, it is almost pure carbon, and carbon is one of the most stable elements.It besides the strong oxidizing acid, acid, alkali and
organic chemicals are very stable, can be made into all kinds of chemical corrosion products.China has
engaged in the study of this aspect of the application, with the lower the price of the carbon fiber, its
application scope will be more and more widely.
