Description

[0001] Technical field: The present invention is a continuous fiber skeleton material molding system, belonging to the technical field of fiber reinforced composite materials. Background Art

[0002] With the booming development of rubber products and the global pursuit of high-performance and lightweight technology, continuous fiber skeleton materials, as a lightweight and high-strength material, are becoming the focus of attention in the rubber products industry. Due to the differences in modulus and polarity between fiber and rubber, the adhesion between rubber and fiber is poor, and the fiber is difficult to be used directly in rubber products. Pre-impregnation of fibers is a common treatment method to improve the adhesion between rubber and fiber. By continuously immersing them in a dipping system and heating and curing them, the resin and latex in the dipping system form a layer of high-performance film on the fiber surface, thereby improving the fusion and adhesion between the fiber and rubber. Traditional continuous fiber pre-impregnation devices have the problems of low fiber impregnation rate and fiber divergence during collection, and the prepared skeleton material has poor performance consistency, which limits its application in industrial production. In order to overcome the shortcomings of the above-mentioned technology, the present invention proposes a continuous fiber skeleton material molding system to improve the pre-impregnation efficiency and quality of continuous fibers.
