The company is mainly engaged in epoxy resin, cyanate resin, PEEK and other unidirectional prepreg strips impregnated with 20%-30% resin. They are mainly divided into carbon fiber thermosetting tape and thermoplastic tape. These tapes don't need isolation paper and can directly be applied to various types of filament winding and fiber placement machines. Resin control is better with no resin adhesion on the surface. At the same weight, the fiber content increased by 10-20% compared with the wet method. Interlaminar shear force, elastic modulus and tensile strength of the fiber are greatly increased. After curing, there is no bubble between layers. Surface features are better and the precision is higher, solving the problems of bubble, stratification and cavity area in the wet process.
