The utility model discloses a poly urethane (PU) composite base material for an automobile roof. The PU composite base material for the automatic roof is characterized in that the PU composite base material is dumbbell-shaped and made by heating and compositing an upper macromolecule hot melting adhesive membrane layer (1), an upper rubber powder layer (2), an upper glass fibrous layer (3), a PU foam plate (4), a lower macromolecule hot melting adhesive membrane layer (5), a lower rubber powder layer (6), a lower glass fibrous layer (7) and a non-woven fabric layer (8). The PU composite base material for the automobile roof is made according to shapes of various automobile roofs of various types, the demand for thermoplastic compression molding of the automobile roofs is met, raw materials cost are effectively saved, meanwhile, generation of waste leftover is reduced, quantity of PU foam which is non-degradable is reduced, and low-carbon and environment-friendly effects are achieved.
