Abstract

The invention relates to a composite sheet for an automotive exterior vortex generator. The composite sheet for the automotive exterior vortex generator comprises matrix resin and a glass fiber layer, wherein the matrix resin and the glass fiber layer are integrated, and the glass fiber layer is coated with the matrix resin. The glass fiber layer comprises longitudinal glass fiber bundles and latitudinal glass fiber bundles, wherein the longitudinal glass fiber bundles and the latitudinal glass fiber bundles are mutually crossed to form a net and each are formed by entwisting 3000-5000 glass fiber filaments. Due to the fact that the sheet can be directly cut for usage, the strength is high, the toughness is higher, the automotive exterior vortex generator manufactured by the sheet is light in weight and is environmentally friendly, and the problem of insufficient strength of existing thermoplastic plastics and discontinuous fiber reinforced composite materials can be effectively solved.
