Are there any criteria for judging the quality of carbon fiber tubes?

As one of the basic products of carbon fiber, carbon fiber tubes can often be seen in high-end fields such as aerospace, medical equipment, and civilian fields such as sports equipment. With the expansion of the carbon fiber market, more and more companies have begun to enter the field of carbon fiber production, and the competition in the carbon fiber pipe industry has become increasingly fierce, and more and more customers have begun to pay attention to the differences between carbon fiber pipes. How to measure whether the carbon fiber tube is of high quality is also a matter of testing technology.

According to the analysis of previous carbon fiber product cooperation cases, the main markets for carbon fiber tubes are in the fields of drones, high-end medical care, industrial manufacturing, automobile rail transit, sports and leisure. The original intention of the application is basically to pursue lightweight, but in Boshi's view, we need lightweight, but not just lightweight. Boshi has customized carbon fiber UAV parts for a company, such as carbon fiber UAV frames, arms, casings, center plates, etc. The use of carbon fiber parts for UAVs not only reduces the weight, but also The endurance time, aircraft mileage, load and other aspects are better than the traditional material UAV.

Of course, the work nature of drones requires light weight, but looking at the entire drone market, you will find that light weight is not the ultimate goal. Excellent performance is the core element of production and competition. It is the ultimate goal. Quantification is just to help build strength in this area. In addition to being lightweight, the linear expansion coefficient of carbon fiber tubes is close to "0", and this is still the case in environments with large temperature differences. In some thermally sensitive fields, a little change in temperature will also affect the measurement accuracy of the instrument, and the application of carbon fiber tubes can undoubtedly solve this problem.

The application of carbon fiber pipes is a replacement for traditional metal pipes. Compared with metal materials such as steel and aluminum alloy, the strength of carbon fiber materials can be as high as 3000MPa or more, which is 6-12 times higher than that of metal materials. Even the strength of ordinary carbon fiber materials is far superior to that of traditional metal materials, but the compliance of strength cannot directly determine that metal pipes can be replaced by carbon fiber pipes from now on. As a non-terminal structural product, the specific requirements of carbon fiber pipe application objects It is the final indicator of carbon fiber pipe.

For example, the mechanical arm made of carbon fiber square tube is used as a mechanical component to replace manual operation. In addition to the requirements for strength, it is necessary to ensure that it maintains a good working condition during long-term operations and even in harsh working environments. And environmental adaptability requirements are also very high. If the material of the carbon fiber manipulator itself is uneven or the blank is defective, it is easy to cause the workpiece position deviation or even breakage when grasping or placing the workpiece. The former will reduce the product quality of the workpiece and increase the rework rate, while the latter will shorten the industrial The service life of the robot leads to the occurrence of safety accidents.

It can be seen that strength can only be used as one of the dominant indicators of carbon fiber pipes, and indicators such as fatigue resistance, environmental adaptability, and accuracy are the key factors that determine the application value of carbon fiber pipes. According to Boshi's observation, the vast majority of custom carbon fiber product manufacturers on the market can provide carbon fiber tubes that meet the strength requirements, but in practical applications, the value of these carbon fiber tubes needs to be further discussed.

In addition to the differences in length, diameter, tube wall thickness and other specifications, the carbon fiber tubes on the market seem to have little difference, but it is these small "differences" that often become an important basis for verifying the quality of carbon fiber tubes. Whether the outer surface of the pipe is smooth and uniform, what is the dimensional tolerance, whether there is delamination or cracking at the punched hole, the appearance is good, but from the inner wall of the pipe, you can see at a glance whether it is real carbon fiber material, not just a 3k coating According to these intuitive methods for judging the quality of carbon fiber pipes, it will be found that the differences between carbon fiber pipes on the market are obvious.

As a part of the structural parts, the quality of carbon fiber tubes is a very important indicator. As the saying goes, "If you want to do a good job, you must first sharpen your tools." High-quality carbon fiber tubes can greatly improve the overall performance of the product. In order to produce high-quality carbon fiber pipes, in addition to good machinery and equipment, the accumulation of relevant technical experience and personnel are also indispensable. The production of carbon fiber pipes does not seem to have much technical content, but the experience brought by different carbon fiber pipes to users is very different. Therefore, from the selection of raw material suppliers, to processing and production, to the final inspection of finished products, Boshi has always maintained high standards and strictly controlled every production detail. The purpose is to improve the quality of carbon fiber pipes and improve the comfort of customers.
