The invention discloses a secondary equipment compartment fender member for glass fiber composite material pouring. The secondary equipment compartment fender member is characterized in that a plurality of square fender member bodies (1) are included, and each fender member body (1) comprises a plurality of through holes (2) used for pre-burying connecting pieces (4), and fender grooves (3) arranged at the left end and the right end of the fender member body (1) and used for filling seam-removing processing materials. According to the secondary equipment compartment fender member for glass fiber composite material pouring, after the fender member is fixedly welded to a compartment body, the through holes and the fender grooves are filled with the glass fiber composite material to remove seams of a protective layer, and the seams do not need to be filled with glue so that the whole protective layer on the outer side of a secondary equipment compartment can form a seamless whole. Besides, the fender member has high corrosion resistance and impermeability so that the secondary equipment compartment can be used for moist areas and other areas where the environment is severe, environment adaptability of the secondary equipment compartment is enhanced, and the service life of the secondary equipment compartment is prolonged.
