Description
Technical field
The present invention relates to composite material 3D printing technique fields, and in particular to a kind of continuity long fibre 3D printing pen.
Background technique
Currently, the consumptive material of 3D printing is broadly divided into four kinds of species of ceramic-like, metal class, composite material class and polymerization.It is compound
Material is by multiple material (at least two), and by the method for chemistry or physics, process is compound, a kind of finally formed mixing
Profile material.It is usually by high-modulus, high intensity, brittleness enhancing class material and low modulus, low-intensity, tough matrix class material, warp
It crosses certain processing to be combined, it is therefore intended that the various characteristics that comprehensive each homogenous material has are in one, to form synthesis
The extremely excellent new material of performance.Carbon fiber is one kind in atmosphere of inert gases, by organic fiber, by high temperature cabonization
And the polymer of the threadiness formed.The performance of carbon fiber is very excellent, and tensile strength reaches 2 times of steel；Modulus is even more steel
7 times.So resin is as carbon fiber enhancement resin base composite wood made of basis material using carbon fiber as reinforcing material
Material, the advantages of both combining, the defect both compensated for has obtained mentioning by a larger margin on the basis of respective material property
It rises.
Pen is one of great invention of the mankind sage of the past, is the tool for writing or painting etc., and internal structure is
With coloured liquid or solid other surfaces of solids are recorded by pen tip in text, symbol, picture etc. by inside.
It to be formed there is presently no the characteristic of 3D printing technique, fiber-reinforced resin matrix composite and pen is combined
The long stapled 3D printing pen of continuity.
Summary of the invention
