Abstract
A kind of filament preimpregnation non-woven fabrics, the preimpregnation non-woven fabrics is Multi-way multi-layer, it is to be formed by endless tow is arranged in parallel vertically per single layer, make ply adhesion by the impregnating resin of every single layer, preimpregnation non-woven fabrics is made, after following process is composite material, intensity increases the preimpregnation non-woven fabrics, weight saving, fiber is than improving in unit volume.
Description
Technical field
The utility model is related to a kind of filament non-woven fabrics of prepreg, are mainly used for machining composite material.
Background technology
Current prepreg cloth organic fabric and multi-axial tricot this two class are process through pre-soaked resin, because interweaving,
During braiding, long filament is bent, frictionally damage.Such as carbon fiber wire is in brittleness, easy damaged.The woven fabric, braiding
Object increases base material ratio because silk, line bending make gap increase, and reduces the fiber ratio in volume.
Invention content
Problem to be solved in the utility model is：A kind of filament preimpregnation non-woven fabrics is provided, the preimpregnation non-woven fabrics is
Multi-way multi-layer has been spaced apart chopped silk thread, every layer of silk, line are vertical, to fiber in manufacturing process with fiber filament Shu Weizhu
The undamaged pre-soaked resin non-woven fabrics of silk.
The utility model is related to a kind of filaments to presoak non-woven fabrics, it is characterized in that vertical endless tow parallel laid is at every list
Layer by every single layer pre-soaked resin, then is superimposed and to form Multi-way multi-layer preimpregnation non-woven fabrics, and described by every single layer further includes between long filament interfascicular
One chopped silk thread is set every one and the above tow, per single layer pre-soaked resin and another layer is bonding, further includes in prepreg
Middle addition adhesive.
A kind of filament presoaks non-woven fabrics, it is characterized in that the single layer of preimpregnation non-woven fabrics includes what different material mixed
Endless tow further includes the spaced endless tow of different material.
A kind of filament presoaks non-woven fabrics, it is characterized in that the single layer of preimpregnation non-woven fabrics further includes that the chopped silk of fiber is mixed
It spins.
The advantageous effect that the utility model obtains：Compared with prior art, asking for bent filaments in prepreg cloth is overcome
Topic, filament preimpregnation non-woven fabrics also overcomes in manufacturing process existing for woven at present, two kinds of prepreg cloths of braiding, to example
Such as the damage problem that the damage and stretching friction of carbon fiber wire generate, reduces gap, increase fiber content ratio, skill in volume
Art difficulty reduces, and reduces production cost, the composite material processed using the filament preimpregnation non-woven fabrics, intensity higher,
Quality is lighter, and shearing force is stronger, and production cost is lower.
Description of the drawings：
Fig. 1 is broadwise single layer schematic diagram
Fig. 2 is warp-wise single layer schematic diagram
Fig. 3 is -45 ° of single layer schematic diagrames
Fig. 4 is+45 ° of single layer schematic diagrames
In figure：
1, it is endless tow
2, it is the silk thread that is chopped
Specific implementation mode：
The present embodiment provides a kind of filaments to presoak non-woven fabrics, and the preimpregnation non-woven fabrics is 1 parallel laid of vertical endless tow
It is set as every single layer, is superimposed again by every single layer pre-soaked resin and forms Multi-way multi-layer preimpregnation non-woven fabrics, every single layer filament interfascicular,
Further include that one, interval and the above tow are equipped with chopped silk thread 2, single layer is bonding using pre-soaked resin and another layer, further includes
Adhesive is added in pre-soaked resin, keeps single layer and another monolayer adhesive stronger.
A kind of fiber prepreg non-woven fabrics, it is characterized in that the single layer of preimpregnation non-woven fabrics includes the length of different material mixing
Tow further includes the spaced endless tow of different material.
A kind of filament presoaks non-woven fabrics, it is characterized in that the single layer of preimpregnation non-woven fabrics includes the chopped silk blend of fiber
Line.
