Abstract
Description
Technical Field
[0001] The utility model belongs to the technical field of carbon fiber material impregnation, and relates to a rapid impregnation device with a continuous drying structure. Background Art
[0002] Carbon fiber material impregnation is an important processing technology. It improves the performance or realizes specific functions by placing carbon fiber in a specific liquid to make it fully penetrate and absorb. The following is a brief description of the carbon fiber material impregnation technology. Carbon fiber has been widely used in aerospace, automobile manufacturing, building structures and other fields due to its light weight and high strength. During the impregnation process, if the carbon fiber material cannot be dried quickly and continuously, it will bring a series of problems. These problems will not only affect the quality of the prepreg, but may also have an adverse effect on the performance of the final product. The following is a detailed description of the possible consequences of this problem:
[0003] Failure to perform rapid and continuous drying can result in insufficient curing of the thermoplastic resin in the prepreg. The impregnated carbon fiber material requires a drying process to remove excess water and solvent, allowing the thermoplastic resin to fully cure and form a stable prepreg structure. Inadequate drying prevents the resin from achieving the desired degree of crosslinking, resulting in a decrease in the prepreg's mechanical properties and an inability to meet high-strength requirements. Therefore, a rapid impregnation device with a continuous drying mechanism is urgently needed to address this issue. Utility Model Content
