Abstract Hot-melt is an important method to produce prepreg. How to control the fiber spreading width and the stability of the width of fiber bundle are the key and difficult points of hot-melt process. In this work, an experimental platform was built based on machine vision detection techno-logy to explore the influence of four process parameters, namely fiber tension, fiber running speed, resin viscosity and resin coating thickness, on fiber bundle spreading width and width stability, with theoretical model and orthogonal experiments conducted. The results show that with the increase of fiber tension, fiber running speed, resin viscosity and resin coating thickness, the spreading width of fiber bundle tends to increase. The resin thickness has the greatest influence on the width of fiber bundle, followed by the resin viscosity, and finally the fiber tension and fiber running speed, and the experimental results are consistent with the theoretical model. The running speed of fiber has the greatest influence on the stability of the width. The higher the running speed of fiber, the worse the stability of the prepreg width. It is worth noting that when the resin viscosity is 1 300 mPa·s, the running speed of the fiber is 3 m/min, the fiber tension is 10 N, and the resin coating thickness is 0.6 mm, the fiber bundle has the widest spreading width and the best width stability.
