The invention relate to a high-strength composite
elastic energy-absorption anti-collision device and a production method thereof. The anti-collision device comprises a
steel tube, a macromolecular close-
cell type foam material core, a high-strength
fiber material layer, a composite
fiber strengthening layer and an SPUA
casting coating, which are arranged from inside to outside in sequence, wherein the axial
peripheral surface of the
steel tube is coated with the macromolecular close-
cell type foam material core; and the axial
peripheral surface of the macromolecular close-
cell type foam material core is coated with the high-strength
fiber material layer. The production method comprises the following steps: manufacturing a macromolecular close-cell foam material through a mould, and placing the
steel tube in the macromolecular close-cell foam material as a strengthening structure, with an overall size meeting an actual requirement; performing mould-free 3D
casting with a rotary
casting machine, including casting bottom-layer high-strength fiber with a 3D flat
nozzle; performing mould-free 3D casting with the rotary casting
machine, including casting the composite fiber strengthening layer with a round
nozzle; and finally, manually casting the SPUA
surface coating, and forming the SPUA
surface coating through natural-temperature curing. The high-strength composite
elastic energy-absorption anti-collision device has the advantages of large
compressive deformation, small counter force,
high energy-
absorption capacity, excellent anti-
corrosion and anti-aging properties, self-floating property, easiness in mounting, no maintenance, long service life and the like.
