Abstract

The invention discloses a structure and a manufacturing method for a high-intensity composite rod piece. The high-intensity composite rod is mainly used for different structures of rod pieces for building, mechanism and daily life, and the high-intensity composite rod is used for substituting a stainless rod piece. The high-intensity composite rod is mainly composed of a spindle (1) and a skin (2) and characterized in that the spindle is made from natural fiber composite material, the fiber direction of the natural fiber composite material is basically the same with the axial line direction of the spindle, and the spindle is mainly used for bearing the axial load and bending load; the skin is glass fiber reinforced plastic which winds the spindle surface, and the skin is mainly used for bearing the torsion load and simultaneously used for protecting the spindle and avoiding aging and corrosion.

Description

A kind of high strength composite bar
Technical field
The present invention relates to a kind of structural type of high strength composite bar, be applied to the stressed member in building, machinery and articles for daily use.
  
Background technique
In modern society's life, rod member product is applied in daily life more and more.Common product comprises clothes hanger, bicycle crossbeam, tricycle for the disabled main structure beam, baby carriage main structure beam, medical bed support etc.Metallic material becomes the preferred material of these member structures due to its good performance and cheap cost.Because common iron easily gets rusty, consider from product life cycle cost, the first-selected stainless steel of high-end product or aluminium are as the material of rod member.Stainless Steel Tube has the features such as high rigidity, high strength, anticorrosive, low cost, is widely used in all types of industries and the product for civilian use.Its shortcoming is that manufacture energy consumption is high, and manufacture process brings severe contamination to society.
In order to solve the shortcoming of the stainless steel wasting of resources, invent a kind of composite bar of high strength, make its have the mechanical property suitable with stainless steel, cost lower, manufacture energy consumption far below stainless steel, have the advantage that the people such as pyroconductivity is low, color and luster is attractive in appearance are liked in daily life simultaneously.Stainless Steel Tube can be substituted and become that stable performance, cost performance are higher, the rod member parts of environmental protection.
Summary of the invention
Rod member in building, machinery and dairy products is mainly by thrust load, flexural load and torsional load, therefore using high strength composite bar to substitute Stainless Steel Tube to realize, just must make the stressed effect of high strength composite bar under the effect of above-mentioned load and stainless steel-like seemingly.
The natural-fiber composite material used in the present invention and glass fibre reinforced plastic material are anisotropic material, the performance in material fiber direction is high, the performance in other direction is low, in order to make full use of the feature of material anisotropy, high strength composite bar is designed to by mandrel and covering two-part contexture, mandrel is natural-fiber composite material, and fiber direction is consistent with the length direction of mandrel, mainly bears thrust load and flexural load.Covering, by the glass fibre reinforced plastics for being wrapped in mandrel surface, mainly bears torsional load, and plays the effect of protection natural fibre mandrel.
Natural-fiber composite material is mainly based on bamboo and wood materials, bamboo and wood materials need control moisture content and be less than 20%, then forms through impregnation compacting, and is processed into the mandrel of required form, mandrel surface brushes the strong resin of water proofing property, as epoxy resin or vinylite.
Covering is frp layer, is to be wound around by glass fiber winding technique or glass cloth to process, and selected resin is the resin that water proofing property is strong, as epoxy resin or vinylite.The winding angle of glass fibre need design according to the size of torsional load suffered by rod member, is generally 30 ° to 90 °.The thickness of glass fiber winding is generally 0.4mm-5mm.
Accompanying drawing explanation
By the description part of carrying out with reference to accompanying drawing hereinafter, better can understand all above-mentioned features, described accompanying drawing is:
Fig. 1 is the schematic diagram of high strength composite bar in the present invention, and 1 is natural-fiber composite material mandrel, and 2 is frp layer;
Fig. 2 is the sectional drawing of high strength composite bar in Fig. 1, and in mandrel 1, the direction of natural fibre is consistent with the length direction of high strength composite bar;
Fig. 3 is the side view of high strength composite bar in the present invention, and the glass fibre 3 in frp layer 2 is 30 ° to 90 ° with the angle of center line of the bar 4;
Fig. 4 is the exemplary plot of high strength composite bar sectional shape in the present invention.
Embodiment
High strength composite bar involved in the present invention, forms primarily of mandrel 1 and covering 2; Wherein mandrel is natural-fiber composite material, and covering is glass fibre reinforced plastics.
Natural-fiber composite material mandrel take bamboo and wood materials as main material, and what formed through the step such as super-dry, impregnation, compacting, machining take natural fibre as the high strength mandrel of main material.In order to ensure the intensity of mandrel 1, need the moisture content controlling bamboo and wood materials to be less than 20%, and ensure that the axial direction of bamboo and woods fiber and mandrel is basically identical, its deviation≤5 °.The sectional shape of mandrel is processed into the shapes such as circle, ellipse, square or polygonal according to actual needs, and at the strong resin of mandrel surface brushing water proofing property, as epoxy resin or vinylite, plays the effect of sealing bamboo and woods fiber eyelet.
Covering outside mandrel is frp layer, mainly be wound around by glass reinforced plastic winding technique or glass cloth and process, use Stetch Wrapping Machine by the glass fiber winding of leaching waterproof resin in mandrel surface, glass fiber winding angle (angle between glass fibre and mandrel axis) controls at 30 ° to 90 °.
In process of production, the processing method of high strength composite bar is as follows:
1, select natural bamboo and wood materials to carry out drying process, control the moisture content of bamboo and wood materials lower than 20%;
2, be coated with phenolic resin at bamboo material surface, multi-layer bamboo wood material is pressed into monoblock sheet material;
3, by plate cutting into strips, the mandrel of various shape is then processed into by mach mode;
4, waterproof resin is coated with on the surface of mandrel, as epoxy resin or vinylite;
5, be fixed on glass fiber reinforced plastic winder by mandrel, be then wound around the glass fibre or the glass cloth that are soaked with waterproof resin, its glass fibre angle and mandrel Angle ambiguity are at 30 ° to 90 °;
6, after mandrel is wound around glass fibre, normal temperature is carried out or be heating and curing (temperature controls below 70 °).

Claims (5)
