Embodiment 1
[0042] Preparation of wear-resistant layer prepreg tape: the reinforcing fiber used in the preparation of prepreg narrow tape is a hybrid fiber of basalt fiber and alumina fiber, the ratio of the two fibers is 2:1, and the reinforcing fiber fabric adopts "mesh cloth / unidirectional cloth / mesh The resin matrix used is polyurethane resin, and the polyurethane resin is made into a film in advance, and silicon carbide hard particles with a total content of 10% of the prepreg tape are pre-dispersed into the film, and the particle size is 0.5 microns. Lay the resin film of pre-mixed silicon carbide hard particles on the release paper, and apply the release paper with the resin film on the upper and lower surfaces of the laminated structure. The fiber fabric forms a prepreg tape, the final resin content of the prepreg tape is 40%, and the width of the prepreg tape is 90mm.
[0043] like figure 1 As shown, the preparation of a new type of continuous carbon fiber composite sucker rod w...
Embodiment 2
[0045] Preparation of wear-resistant protective layer prepreg tape: the reinforcing fiber used in the preparation of prepreg narrow tape is a hybrid fiber of silicon carbide fiber and alumina fiber, the ratio of the two fibers is 4:1, and the "mesh cloth / plain weave / twill cloth / mesh cloth "Laminated structure, the resin matrix used is polyurethane resin, and the polyurethane resin is pre-made into a film, which is pre-dispersed into the film with silicon carbide hard particles with a total content of 15% of the prepreg tape, and the particle size is 0.4 microns. Lay the resin film with pre-mixed hard particles on the release paper, apply the release paper with the resin film on the upper and lower surfaces of the laminated structure, and combine the film and the fiber fabric by continuous hot-melt impregnation A prepreg tape is formed, the final resin content of the prepreg tape is 35%, and the width of the prepreg tape is 10 mm.
