Nanjing VIC Advanced Material Co.,Ltd supply the CFRP product have the features of light weiht, high strength, high modules, it is important for the industry which require light weight. we use the raw carbon fiber material from reliable vendor.

the raw material, carbon fiber, fiber glass, resin, epoxy and vinyl

the carbon fiber pipe have the regular shapes: carbon fiber tube, carbon fiber tripod pipe, carbon fiber square tube,CFRP exhaust pipe, CFRP rectangular tube etc.

They have the below advantages:

1. Low density, light weight, high strength and modulu

The density is 1.4-1.8g/cm3, 25% of steel, it is easy to construction and shipment, and the strength is dozens of times that of plastic

2. corrosion resistant, aging resistant, long service life

it works in corrosion and humidity environment, the service life is about 20years.

3. Impact resistance Good electrical conductivity, No magnetism, and good structure stability. It can be designed as per request.

4. Thermal endurance, fire resistance

It keeps good mechanical property under low temperature and will not melt under high temperature. The temperature range is -50°C---250°C.

The specifications of the CFRP tubes

We use the pultrusion technology to produce the carbon fiber tubes.

The pultrusion technology process and asvantage

Pultrusion is a method of manufacturing continuous fiber reinforced composites profiles. The manufacturing process is that where molten plastic or metal is pushed through a die. However, with pultrusion, the material is "pulled" through a die.

The Pultrusion Process

Raw fiber (glass, carbon, aramid, etc) is pulled off of doffs or rolls from a creel racking system.

The fiber is pulled through a bath of thermosetting resin. Most often the resin is polyester resin, but also vinyl ester, epoxy, and more recently, urethane.

1)Using guiding systems, the impregnated fiber is led through a heated die. The entrance of the die is often cooled to avoid curing the resin while excess resin is squeezed off.

2)As the fiber and resin is pulled through the heated die, the resin cures and exits as a fully formed composite. The shape of the pultruded composite part will match the shape of the die.

3)All of this is accomplished by a set of "pullers" or "grippers" which are pulling this material at a consistent rate.

4)At the end of the composite machine is a cut-off saw, which cuts the pultruded profiles at a desired length.
