Description
Technical field
The present invention relates to composite material pultrusion technical fields, and in particular to a kind of glue-injection box and a kind of fiber reinforcement hair
Steep the tinuous production and production method of composite material.
Background technique
Composite material is the material with obvious split-phase feature that two kinds or more of material is mixed to form, form and property
It can be different from the individual material of any of which, main component is basis material and reinforcing material, and wherein fiber is most often
Reinforcing material.Usual composite material refers to the material in final form after molding, and basis material and strengthening material
The material of form after material mixing before final molding is referred to as composite material precursors.
Continuous fiber reinforcement foam composite material can either give full play to the strength advantage of fiber, can reduce composite wood
The density of material is a kind of composite material of low-density and high-strength, has broad application prospects, such as replaces timber production pillow
Wood, sash, building floor and enclosed structure, plank road plate etc..Patent (application number: 200610103934.3) discloses one kind
Glass fiber reinforced polyester urethane composite material crosstie and its manufacturing equipment and manufacturing method, still, the method that this technique uses
It is that the mode being ejected into liquid matrix material i.e. polyurethane resin on glass fibre carrys out sized glass fibres formation composite material
Precursor, then composite material precursors is made to be cured as composite material as mold enters drying tunnel；The similar continuous slab of this method is free
The technique of foaming has several problems that can not solve: 1, it is filled out due to relying solely on composite material precursors free foaming in shaping mould
Mold filling chamber realizes the distribution of fiber in the composite, can not position fiber according to the spatial position of design, this is with regard to nothing
Method plays the humidification of fiber to greatest extent, can not also manufacture shape according to the distributing position of stress distribution design fiber
Complicated product；2. being difficult rapidly due to carrying out wetting fibre by the method on injection liquid matrix material to fiber by fiber
It is impregnated with, thus will affect the boundary strength between basis material and fibrous material, the final performance for influencing composite material；Together
When, this method is also difficult rapidly disposably to be impregnated with a large amount of fiber, so being difficult to manufacture large-sized composite material；3. mould
Tool is complicated, and investment is big.The prior art needs to improve.
Summary of the invention
In order to solve the above technical problems, the invention proposes a kind of glue-injection box and a kind of fiber forced foamed composite materials
Fibrous material is distributed by tinuous production in advance by distribution frame, then fibrous material pass sequentially through glue-injection box, foam device with
And molding die, glue-injection box make liquid matrix material rapidly and are fully impregnated with fibrous material, foam device makes liquid matrix material
Material, which foams and then enter back into advance in molding die, completes sufficiently foaming, guarantees that the fibrous material in final molding composite material is pressed
It is distributed and is fully extended according to the position of design.
In order to achieve the above objectives, technical scheme is as follows:
As shown in Fig. 3-Fig. 7, a kind of glue-injection box, before forming composite material for liquid matrix material wetting fibre material
Body is used to the infiltration channel 21 of fibrous material infiltration and enters infiltration for liquid matrix material lead to including 2 and 2 or more
Glue injection channel 22 in road 21, the infiltration channel 21 include for the feed inlet 211 of fibrous material entrance and for feed flow
