High Strength Pultrusion Carbon Fiber Tube Pullwinded Carbon Fiber Pipe

Product Specification

High Strength Pultrusion Carbon Fiber Tube - Pullwinded Carbon Fibre Tubes
 

This type of profile has high specific mechanical resistance (related to its weight), lightness, rigidity, great resistance to fatigue and vibrations, resistance to oxidation and corrosion, low coefficient of thermal expansion, and durability.

Pultrusion is a technique of continuous production of linear profiles with a constant section. This process has many similarities to extrusion, the main difference is in the feeding system: in extrusion, the material is pushed through the matrix (mold), and in pultrusion it is extracted from the matrix. This procedure does not allow variations in shape, sections, or curves. Products that can be obtained by this process can have sections or thicknesses of up to approximately 15mm, with epoxy resins and up to 70mm with polyester resins.

Products made with this technology have excellent tensile strength characteristics due to the linear orientation of the fibers in the direction of the axis of the profile; if it is also necessary to have a good transversal resistance, a woven fabric is used as a backing in specific quantities and weights.

Q: Your quotation does NOT meet my target price
A: We can propose materials, accessories, or design alternatives to lower the price of your project
Q: What is carbon fiber used for?
A: Carbon fiber -- sometimes known as graphite fiber -- is a strong, stiff, lightweight material that has the potential to replace steel and is popularly used in specialized, high-performance products like aircraft, race cars and sporting equipment.
Q: Is carbon fiber stronger than steel
A: Carbon fibers are classified by the tensile modulus of the fiber. ... Thus, the strongest carbon fibers are ten times stronger than steel and eight times that of aluminum, not to mention much lighter than both materials, 5 and 1.5 times respectively.
Q: Why is carbon fiber so expensive?
A: Another carbon fiber cost factor is energy. ... It takes a lot of energy to reinforce each fiber with carbon atoms. Energy, is also required to bundle the carbon together into fibers and threads. Energy costs are probably the most expensive factor in carbon fiber manufacturing.
Q: What are the advantages and disadvantages of carbon fiber?
A: Carbon fiber reinforced polymer (CFRP) materials possess good rigidity, high strength, low density, corrosion resistance, vibration resistance, high ultimate strain, high fatigue resistance & low thermal conductivity. They are bad conductors of electricity and are not magnetic.
Q: Is carbon fiber resistant to water?
A: The carbon fiber in the composite does not absorb water from the environment, and its resistance remained unchanged when immersed in water.
Q: Is carbon fiber the future?
A: The future of carbon fiber is undoubtedly on a positive course. However, the speed at which carbon fiber integrates into larger commercial markets and more and more common applications is largely dependent on the capabilities of existing carbon fiber manufacturers.
