Any material will age, and carbon fiber pipe is no exception, we compare carbon fiber pipe with a metal pipe, which can be a more intuitive comparison analysis.
Aluminum pipe, aluminum pipe performance compared with steel pipe and carbon fiber pipe, the strength is much lower, but the anti-aging performance of aluminum pipe is good, because the strength of aluminum pipe is relatively low, it can not be well applied in high-strength operation scenarios.
The strength of steel pipe is higher than that of the aluminum pipe, the performance is also very stable, and the production cost is low, the price is relatively low, so the steel pipe has been applied in many fields. Because it is a metal product, the quality of the steel pipe itself is relatively high, and it is easy to bend, and it is particularly easy to rust in an acid-alkali environment, so it is not suitable in some special areas.
Carbon fiber pipe, the strength of carbon fiber pipe is 3 times that of steel pipe, the quality is only one-fifth of the steel pipe, making the strength and modulus above the advantages much higher than steel pipe and aluminum pipe, and strong corrosion resistance, long life. The disadvantage is that it will show brittleness when it exceeds the bearing range. Due to its high bearing performance, brittleness is not a particularly obvious disadvantage. The corrosion resistance is much higher than that of steel pipe and aluminum pipe.
Aging is a problem that all materials will have, affected by temperature, wind, environmental humidity, and other environments, such as temperature rise, it will cause the carbon fiber tube to soften, beyond the melting point, it will decompose. Although the carbon fiber itself is resistant to high temperatures, the carbon fiber tube contains resin, and the high-temperature resistance of the resin is not high, and the weathering will occur over time. If the ambient humidity is high, in the strong acid and alkali environment, it will also cause the performance of carbon fiber tubes to decline. If it enters from the cross-section, it will affect the overall performance of the carbon fiber tube, so that its performance is reduced, the chemical medium usually permeates and diffuses along the surface – interface – internal direction, and the product precipitation and loss after corrosion will change the internal and external surface topography of the composite material.
Although the carbon fiber pipe will age, the speed of aging will be very slow, its overall life is still much higher than the metal pipe. The service life of a carbon fiber tube is 10-20 years, after which another one can be replaced to ensure its stable performance.
