Into the weight/mass percentage composition of carbon fiber core 1 is 33.1-28.3%, 1 a diameter of 11--14mm of carbon fiber core.Every carbon fibre
The monofilament quantity of dimension is an important indicator of carbon fiber, and monofilament quantity is bigger, and cost is higher, but intensity is higher while sucker rod
Also can overstriking.Carbon fiber of the present invention from monofilament quantity for 12K, while the intensity requirement of coiled rod is met,
Economy is taken into account.Limited by use environment and production standard, the diameter of coiled rod is usually defined as several fixations
Value, according to the difference of coiled rod diameter, 150-242 roots are limited in by the quantity of 12K carbon fibers, can ensure continuous oil pumping
Production cost is reduced while bar intensity, sucker rod, which has integrally also lightened, reduces energy consumption, ensures the other of coiled rod
Layer will not because of carbon fiber core 1 diameter it is excessive and be forced to compress, and then influence the overall performance of coiled rod.The present invention
It is 33.1-28.3% by the weight/mass percentage composition of carbon fiber core 1, this is that pole is necessary.It is defined in the radical of carbon fiber
In the case of, the restriction to the weight/mass percentage composition of carbon fiber core 1 is both the restriction to coiled rod quality, and to even
The restriction of the ratio of carbon fiber content and other each component contents in continuous sucker rod.The timing of diameter one of coiled rod, carbon are fine

Divide content 32-38%, longitudinal glass layer 4 is made up of 42/2400tex-106 piece/2400tex glass fibres, longitudinal direction
Glass layer 4 mainly serves anti-shearing, therefore the line density of glass fibre is necessarily claimed.Line is used in the present invention
Density is 2400tex glass fibre, to ensure good anti-shear ability.And in actual production, line density is too high (i.e. fine
Tieed up thick) bond effect of epoxy resin and the uniformity of longitudinal glass layer 4 can be had a strong impact on, therefore, meeting shearing resistance
In the case of cutting performance, line density is set to 2400tex, unsuitable too high.
