With the continuous expansion of the scale of the carbon fiber industry, more and more fields and industries have appeared in the shadow of carbon fiber products, the black three-dimensional pattern effect, coupled with super mechanical properties, enough to make it become a new business card in the modern industrial field. Carbon fiber products are lightweight and durable, but if you want to meet the needs of use, you need to pay greater investment in the processing stage, which is also one of the basic thresholds of the carbon fiber industry. In this paper, we analyze the low yield of carbon fiber products when processing.
Why is it difficult to improve the yield of carbon fiber products?
Why is it difficult to improve the yield of carbon fiber products?
The process of processing carbon fiber products and processing metal products is completely different, it can not use pouring or die casting process, the current commonly used ways are pultrusion, winding, molding, etc., and the process of irregular shape carbon fiber products is less, usually better molding.
Molding process processing carbon fiber products, usually need to design and make molds in advance, in order to improve the product yield, the accuracy requirements of the mold will be relatively high, just this step to maximize the completion has been not a small difficulty, not to mention the follow-up there are more than ten processes need to be completed one by one. Any mistake in the details may lead to a significant decline in the yield of carbon fiber products, summarized from the production process, there are mainly the following aspects.
1, Material characteristics: Carbon fiber has unique properties that make it suitable for many applications, such as high strength, light weight and excellent thermal conductivity. However, these properties also make carbon fiber sensitive to processing conditions. The brittleness of carbon fiber makes it vulnerable to damage during handling, molding and curing, resulting in reduced production.
2, the manufacturing process is complex: carbon fiber products are usually manufactured through a multi-step process, involving the synthesis and stabilization of the precursor material, followed by carbonization and post-processing steps. Each stage requires careful control of various parameters, such as temperature, pressure, and curing time. Any deviation or inconsistency in these parameters can result in defects and lower yields.

3. Cost and efficiency are difficult to balance: carbon fiber production can be expensive due to high raw material costs and energy-intensive manufacturing processes. Any increase in yield must be balanced with cost considerations, improving yield usually requires optimization of manufacturing processes, equipment and raw materials, which are huge prerequisite inputs, inputs are not in place, and the yield rate in subsequent processing will not be maintained at a higher level.
4, quality testing is difficult: to ensure the consistent quality and performance of carbon fiber products is crucial, manufacturers not only need to implement strict processing steps to complete the production of carbon fiber products, but also need to have qualified testing means, accurate discovery of problems and defects in products. In the processing process, the problem is found at the early stage and adjusted in time, which helps to improve the yield and reduce the cost and time of secondary processing.
5, the threshold of expertise is high: carbon fiber manufacturing is a specialized field that requires expertise in materials science, chemistry and engineering. Developing innovative technologies to improve yield requires a deep understanding of the complex interplay between process parameters, materials, and resulting fiber properties. Progress in the field often relies on continued research, development, and collaboration between industry and academia.
Carbon fiber is an imported product for us, and the investment of resources is relatively late, so the overall technology is weak, and the overall industry scale is relatively small. The processing of carbon fiber products is the middle and downstream part of the carbon fiber industry, the upstream part of the development is backward, is bound to affect the development of the middle and downstream part, the lack of equipment, technology, experience is the crux of the problem, but also the future of China's carbon fiber development must be improved.
