The invention discloses a fiber reinforced plastic manhole cover which comprises a circular cover body, wherein rabbets used for being matched with a housing washer fixed on the ground are formed in the periphery of the cover body; through holes and raised edges uniformly distributed on the bottom surface of the cover body are arranged on the cover body; raised reinforcing ribs adopting a cross shape are arranged on the bottom surface of the cover body; and symmetrical triangular ribs are arranged on the two sides of each raised reinforcing rib at intervals. According to the fiber reinforced plastic manhole cover, the raised reinforcing ribs adopting a cross shape are arranged on the bottom surface of the cover body of the manhole cover, and the triangular ribs are arranged on the two sides of each raised reinforcing rib at intervals, so that the strength of the manhole cover is obviously improved, the rigidity is improved, the capacities of damage resistance and deformation resistance are improved, and the service life is prolonged.
