The invention relates to a composite material energy-dissipation anti-collision device. The composite material energy-dissipation anti-collision device is provided with a plurality of interconnected energy-dissipation units, and each energy-dissipation unit comprises a shell, wherein the shell comprises an outer shell body, an inner shell body arranged inside the outer shell body in a sleeving mode and a filling material, and the filling material is filled between the inner shell body and the outer shell body; the shell of each energy-dissipation unit is provided with a connecting portion connected with the shell of the adjacent energy-dissipation unit, wherein the connecting portion comprises an embedded part, and the embedded part is fixed to the shell; each embedded part comprises a fixing plate, wherein a fixing hole is formed in the fixing plate, or a bolt is arranged on the fixing plate, and every two adjacent energy-dissipation units are fixed to each other through the corresponding embedded parts. According to the composite material energy-dissipation anti-collision device, the two adjacent energy-dissipation units are fixed to each other through the corresponding embedded parts, the two embedded parts can be tightly attached to each other, in addition, the bolts can be arranged in the fixing holes in a penetrating mode, the connection strength is good, compared with a connection mode between a male tenon and a female tenon, the connection strength is improved by 5-10 times, the impact load can not be generated, and the fatigue load is greatly reduced.
