Embodiment 1

[0043] Such as Figure 4 As shown, a composite energy-dissipating fender 1 includes a shell 2 and an energy-dissipating filler 3 wrapped in the shell 2. The composite energy-dissipating fender 1 is rectangular and is cured by glass fiber and unsaturated resin. A solid shell 2 is formed; the energy-dissipating filling body 3 includes energy-dissipating materials 4 and energy-dissipating ribs 5, and polyurethane foam is used to manufacture several cuboid-shaped unit blocks 7, and several unit blocks 7 are combined to form energy-dissipating materials 4, and the unit blocks 7 have the same shape and size, and the energy-dissipating ribs 5 include glass fiber strands and unsaturated resin; the twelve edges of the unit block 7 are divided into five equal parts, and the endpoints on the six faces are perpendicular to the The ribs are provided with energy dissipation grooves 8, and the energy dissipation grooves 8 on each surface form a rectangular mesh network structure, and the fib...

Embodiment 2

[0045] Such as Figure 5 As shown, a composite energy-dissipating fender 1, a shell 2 and an energy-dissipating filler 3 wrapped in the shell 2, the composite energy-dissipating fender 1 is rectangular, and the shell 2 is a composite surface layer 9 A sandwich shell 2 filled with a sandwich material 10, the composite surface layer 9 is cured by carbon fiber and vinyl resin, the sandwich material 10 is polyurethane foam; the energy dissipation filling body 3 includes energy dissipation materials 4 and energy dissipation ribs 5, Use PMI foam to manufacture several cuboid-shaped unit blocks 7, and several unit blocks 7 are combined to form an energy dissipation material 4. The shape and size of the unit blocks 7 are consistent, and the energy dissipation ribs 5 include carbon fiber tow and vinyl resin; all of the unit blocks 7 are opened Elongated energy-dissipating grooves 8, all the energy-dissipating grooves 8 on each unit block 7 are connected to each other, and the energy-di...

Embodiment 3

[0047] Such as Figure 6 As shown, the difference from Example 2 is that the energy-dissipating fender 1 of composite material is in the shape of "7" and can be directly fixed on the bridge by bolts, and the surface layer 9 of composite material is cured by aramid fiber and epoxy resin. The sandwich material 10 is polyvinyl chloride foam, the energy dissipation material 4 is polyvinyl chloride foam, the filament material is aramid fiber, and the resin material in the energy dissipation rib 5 is epoxy resin. A plurality of through holes 6 are opened, and aramid fiber tows are placed in the through holes 6. All the through holes 6 are connected with the external space of the energy dissipation material 4. Finally, a vacuum introduction process is used to inject molten unsaturated resin into an integrally formed composite material dissipation material. Can fender 1.

Abstract

The invention provides a composite-material energy-dissipation fender which comprises a shell and an energy-dissipation filling body wrapped inside the shell. The energy-dissipation filling body comprises energy-dissipation materials and a plurality of energy-dissipation ribs, the energy-dissipation ribs are distributed inside the energy-dissipation materials and / or between the energy-dissipation materials and the shell, and the energy-dissipation ribs are connected with the shell into a whole. The energy-dissipation ribs of the composite-material energy-dissipation fender form a longitudinally-transversely staggered net structure, the high shearing strength and the certain elastic deformation buffering capacity are achieved, the shell can be protected from large shearing deformation, and the composite-material energy-dissipation fender is good in overall collision avoidance effect, low in manufacturing cost, long in service life and convenient to maintain and repair.

Description

technical field [0001] The invention relates to the technical field of water building safety protection, in particular to a composite energy-dissipating fender, specifically a fender used to reduce the impact accidents of various bridge piers, bridge towers, caps, docks and other water buildings. Composite material energy-dissipating fender and its manufacturing process under the impact force. Background technique [0002] As we all know, ship (vehicle) collision accidents have been happening all over the world, and the frequency of ship collision accidents is much higher than we imagined. The loss of life, property damage, and environmental damage caused by ship-bridge accidents is staggering. Many ship collision accidents range from losses of tens of thousands of yuan to casualties, losses in millions, tens of millions or even billions of dollars, and a large number of indirect losses are even more difficult to calculate. Therefore, it is particularly necessary to take a...
