Abstract

The invention specifically relates to a lightweight composite material structure with super-high absorption energy and an application of the lightweight composite material structure. The structure comprises, from inside to outside, a first material inner layer, a first buffer layer, a second metal inner layer, a second buffer layer, a third metal inner layer, a third buffer layer, and a metal outer layer. The first buffer layer comprises a plurality of supporting tubes perpendicular to the first material inner layer and PU foam filling gaps between tube walls of the supporting tubes. The second buffer layer comprises PVC foam or aluminum foam. The third buffer layer comprises a plurality of supporting tubes perpendicular to the third metal inner layer and PU foam filling gaps between tube walls of the supporting tubes. The structure is low in fabrication cost and easy to operate on site. Compression resistance of materials and an effect on protecting the supporting tubes from deformation through the foam are furthest utilized, excellent performance of impact resistance is furthest developed, and the structure is reduced in weight and saved in materials, so that a deserved protection effect is played on bridge piers.

Description

The light composite material structure of a kind of superabsorbent energy and application
Technical field
The present invention relates to a kind of composite structure, be specifically related to light composite material structure and the application of a kind of superabsorbent energy.
Background technology
The protection of existing water route bridge pier is generally by adding steel column around bridge pier or the collision come from ship kept out by reinforced column; but these guard columns can not be very thick; because the navigation of ship can be affected like that; so these protect the protection to bridge pier is limited; and it is also unrealistic to carry out such protection for highway bridge pier; because guard column can reduce vehicle flowrate, it is often more important that the safety of driving is had large effect, increases the probability of traffic accident. Therefore, be badly in need of a kind of structure bridge pier can wrapped, though be knocked also can absorbing impact energy, make bridge pier injury-free, be more unlikely to occur bridge pier sever accident, it is to avoid cause even more serious consequence.
Summary of the invention
In order to absorb because clashing into the energy produced, avoid the accident even more serious because clashing into bridge pier generation, safer protection bridge pier, the invention provides the light composite material structure of a kind of superabsorbent energy, it is characterized in that: from internal layer to outer layer, include the first material inner layer successively, first cushion, second inner metallic layer, second cushion, 3rd inner metallic layer, three buffer layer and metal outer, described first cushion includes being provided with several the stay tubes being perpendicular to the first material inner layer and being filled in the PU foam between several support tube wall gap, described second cushion includes PVC foam or aluminum foam, described three buffer layer includes being provided with several the stay tubes being perpendicular to the 3rd inner metallic layer and being filled in the PU foam between several support tube wall gap.
Further, described stay tube is one or the combination of fiberglass pipe, carbon fiber pipe, bamboo trunk or metal tube.
Further, the thickness of described metal outer is 3-5mm, and the thickness of described second inner metallic layer and the 3rd inner metallic layer is 1-2mm, and the thickness of described PU foam is 150-250mm.
Further, described second cushion also includes small hollow ball and/or nanometer native powder.
Further, the thickness of described stay tube: diameter is than for 0.05-0.15.
Further, described first material inner layer is made up of stainless steel alloy, glass fibre, carbon fiber or high density polyurethane foam.
The application on bridge pier of a kind of light composite material structure according to any one of claim 1-6.
The invention have the benefit that the present invention adopts very novel design concept that can be practical; cost is low; it is prone to execute-in-place; utilize the anti-compression property of material to greatest extent; and foam is to a restrictive function for stay tube deformation, present configuration can play the premium properties of crashworthiness to greatest extent, and alleviate weight simultaneously and save material; absorb the crash energy of ship or car to greatest extent, thus bridge pier being played due protective effect.
Accompanying drawing explanation
Fig. 1 is the structural representation of the present invention;
Fig. 2 is the application schematic diagram of the present invention;
Wherein, the first material inner layer 1, the second inner metallic layer 2, the 3rd inner metallic layer 3, metal outer 4, stay tube 5, a PU foam 6, the second cushion 7, bridge pier 8, light composite material structure 9.
Detailed description of the invention
Below in conjunction with accompanying drawing, the present invention is further described: the invention provides the light composite material structure of a kind of superabsorbent energy, it is characterized in that: from internal layer to outer layer, include the first material inner layer 1 successively, first cushion, second inner metallic layer 2, second cushion 7, 3rd inner metallic layer 3, three buffer layer and metal outer 4, described first cushion includes being provided with several the stay tubes 5 being perpendicular to the first material inner layer 1 and being filled in the PU foam 6 between several stay tubes 5 tube wall gap, described second cushion 7 includes PVC foam or aluminum foam, described three buffer layer includes being provided with several the stay tubes 5 being perpendicular to the 3rd inner metallic layer 3 and being filled in the PU foam 6 between several stay tubes 5 tube wall gap, described stay tube 5 is fiberglass pipe, the thickness of described metal outer 4 is 3-5mm, the thickness of described second inner metallic layer 2 and the 3rd inner metallic layer 3 is 1-2mm, the thickness of described PU foam 6 is 150-250mm, described second cushion also includes small hollow ball, the thickness of described stay tube 5: diameter is than for 0.05-0.15, described first material inner layer 1 is made up of stainless steel alloy.
Actually, a stay tube in this structure can be for fiberglass pipe, carbon fiber pipe, bamboo trunk or metal tube a kind of or their any combination, second cushion can also include small hollow ball and/or nanometer native powder, this structure 9 is applied on protection bridge pier 8, the novel light composite structure of this superabsorbent energy being prone to field fabrication forms through agitation as appropriate process by a stay tube embeds the mixture of PU foam and additive, its performance depends on how make PU liquid and how to add additive and stir, the design of sandwich, nanometer native powder and the hollow ball used, prefabricated temperature and pressure and time etc., and for the density to PU, the embedded model of stay tube and and the collocation of the first material inner layer, pass through computer-aided engineering, this novel light sandwich is made to reach the best protection effect to bridge pier.
