Description
Technical field
It is especially a kind of to utilize the fibre-reinforced thermoplastic resin of connection the present invention relates to a kind of Composites Molding Techniques
Composite technology forming technique, specifically a kind of 3D printing method of continuous fiber reinforced thermoplastic resin based composites
And print head.
Background technique
A kind of rapid shaping (Rapid Prototyping) be integrated application CAD, high molecular material
The novel manufacturing process in the cutting edge technologies such as science, Digital Control field, main thought successively or are point by point accumulated by material
And produce the space geometry entity of certain structure.The technology subtracts manufacture process (by the extra of blank different from traditional
Material removal obtains target entity), and improving becomes increasing material manufacturing technique, makes no longer to need molding die in manufacturing process,
Shorten the Element Design period, the 3D solid of arbitrarily complicated structure can be produced, not the limit by process conditions and process equipment
System, and the technology will not generate excess waste, stock utilization is high.The 3D printing technique that earlier 2000s occur is a kind of allusion quotation
The rapid shaping technique of type, the technology is using powder such as metal, plastics, ceramics as basic consumptive material, based on digital model file benefit
Go out the part of labyrinth with in-situ solidifyings technique, the layer-by-layer lay-up molding such as fusion sediment, laser sintered, photoetching solidification.The skill
Art has been widely used in the industries such as aerospace, automobile, plastic products, biologic medical.
Fused glass pellet (FDM) technology relies on its lower cost and more excellent realizability, achieves in recent years
Very big occupation rate of market, the Table top type FDM three-dimensional printer of the miniaturization especially occurred, so that individual consumer can also be certainly
Row designs and produces complicated and have certain part for using function.But the technique using can heating and melting thermoplastic resin
Consumptive material is moulding material, and material itself does not have continuity, and micel spacing is larger in layer, and the successively process characteristic of laying
Poor inter-layer bonding force is caused, these features result in that part brittleness is big, and impact strength is low, and easily-deformable, load-carrying properties are poor.
Although thering is scholar or enterprise to optimize mechanical property by the way of structural Topology Optimization in the design process of part, also or
Particle is added in thermoplastic matrix, the reinforcements such as chopped strand cannot fundamentally improve fusion sediment technique eventually and be formed
The mechanical property of component.Especially for the complex component in aerospace field, lightweight and high-intensitive requirement are increasingly tight
It is severe, although the increasing material manufacturings such as fusion sediment technique can significantly save raw material, the difficulty of part manufacturing is reduced, it is made
Poor product mechanical property is also to limit the main reason for it in industry develops.
In basis material be added continuous fiber reinforcement phase, formed two-phase or and its above composite material, can reach
Higher specific strength, specific modulus, and the molding part of this material have preferable designability, toughness, impact resistance and
Fatigue performance.It is large range of to use composite wood in order to reach light-weighted design requirement in aerospace field
Material, but its forming process suffers from the restriction of die shape, it is difficult to mold complex contour structures.For continuous fiber
The thermoplastic composite of enhancing forms, and has the thermoplastic composite 3D printing of scholar and enterprise development continuous fiber reinforcement
Method and apparatus.Mark Forged company of the U.S. develops the continuous fiber 3D printer [WO of Mark series
2014197732], fiber separates laying, fiber-resin interface, interface layer associativity with thermoplastic matrix in print procedure
Can be poor, although the comprehensive performance in remaining all directions cannot reach higher having preferable mechanical property along machine direction
Standard；A kind of continuous fiber reinforced thermoplastic composite material of the colleges and universities such as Nihon University, Tokyo Institute of Technology scholar's joint research and developments
3D printing method, fibre resin blend method is more simple, fiber be not blended sufficiently with resin i.e. by extruder head directly squeeze
Out, since extruder head tip is to the squeezing action of mixture, fiber is distributed in resin surface, and fiber in track after molding
Volume content is smaller.Xi'an Communications University Tian little Yong et al. has developed continuous fiber enhancing composite material print head
[CN201410325650.3] and multistage wire feed print head [CN201510633569.6], the former print head design method is more
Uniqueness, print head inside are equipped with hollow screw, and fiber is passed through by hollow channel, along fiber week after screw rod drive molten resin downlink
It being wrapped to by fiber, resin has more uniform distribution in final traces, but its fibrous inside tow is not mixed with resin,
Dry fibers gap is formed after molding in entity, influences the mechanical property of component；The multistage wire feed print head structure is more
Complexity, the mixing of multiple material makes its shaped component have preferable toughness, but its fibre bundle is in every grade of melt chamber and matrix
Only simple contact mixing, since the viscosity of molten resin is larger, it is difficult to so that it is sufficiently infiltrated the fibre bundle of all directions, meanwhile,
When fiber moves in multi-stage pipeline, due to friction, extruding force is unevenly distributed in pipeline, causes the part point of fibre bundle
Fork is broken and blocks and squeeze out pipeline, finally makes fibrous fracture and influence forming process, secondly, different high performance resins has
Different fusing points, wherein 200 DEG C nearly with the melting point difference of polyether-ether-ketone of polylactic acid, the heat transfer effect of neighboring chambers also will affect base
The normal condition of body material.There are also several about continuous fiber reinforced composites 3D printing method both at home and abroad or sets
Standby relevant report, principle are similar with above-mentioned report.
In conclusion the 3D printing method of existing continuous fiber reinforced composites has the following problems:
1) when leaving the factory, surface active groups are only adapted to the impregnation process with thermosetting resin to each fiber.?
When untreated fiber being blended with molten thermoplastic resin using simple measure, it is difficult to infiltrate fiber sufficiently with resin,
This causes the fiber-resin interface of component poor.
2) big bunch fiber is band-like in flattening, and existing 3D printing method is difficult with big bunch fiber, and small bunch fiber
Shaping speed is slow in forming process, surface quality after molding, fibre resin volume fraction, fibre resin distribution situation, layer
Between the performance indicators such as binding force be difficult to control.
3) existing method, due to the Local Bifurcation of fiber, fracture, be easy to cause fiber in cavity in print procedure
Accumulation, blocking, impact forming process, meanwhile, fiber is in loose, irregular distribution in final traces, so that
The load-carrying properties of component are affected.
Summary of the invention
Used connection when the purpose of the present invention is for existing thermoplastic resin based composite material 3D printing forming
Fiber size is smaller, and cannot realize effectively dipping to connection fiber and cause shaping speed is low, scantling be limited it is larger, at
The low problem of type part comprehensive performance invents one kind and is suitable for larger-size fibre bundle, and shaping speed is fast, and surface quality mentions
Height, while the interfacial combined function between fiber and thermoplastic matrix is good, component fiber content is high, and fiber solidity is high, prints structure
The 3D printing method for the continuous fiber reinforced thermoplastic resin based composites that the mechanical property of part improves, while a kind of phase being provided
The print head answered.
Technical solution of the present invention first is that:
