The invention discloses a high-specific-energy-absorption bionic composite material structure a and manufacturing method. The high-specific-energy-absorption bionic composite material structure comprises an orthohexagonal outer pipe, an orthohexagonal inner pipe, a rib plate and a circular pipe; the orthohexagonal outer pipe and the orthohexagonal inner pipe are connected through the rib plate; the vertex connecting position of the orthohexagonal outer pipe and the orthohexagonal inner pipe adopts the structural form of the circular pipe; and the orthohexagonal outer pipe and the orthohexagonal inner pipe form an integrated compact spider web structure. The integrated compact spider web structure has high stability, and the whole structure cannot fail due to local damage; and the orthohexagonal outer pipe, the orthohexagonal inner pipe, the rib plate and the circular pipe are made of carbon fiber resin matrix composite material. According to the manufacturing method, the energy absorption efficiency of the energy absorption pipe can be greatly improved by utilizing a combined mold and a vacuum bag forming process.
