Abstract
The invention discloses the manufacturing process flows of carbon fiber prepreg, can prepreg of the One-step production containing polyaxial carbon fiber.The non-twist carbon fiber prepreg of global general-use is 90 ° at present, it needs to design laying angle according to product performance demands before composite article is made, laying quantity and overlay thickness, carry out complicated artificial laying process, this easily leads to the unstable of the accuracy of carbon fiber angular distribution, it is unstable to directly result in final product performance, yields is insufficient.Artificial laying also limits production efficiency and increases production cost.Polyaxial mechanical laying disclosed in this invention is integrally formed mode and revolutionizes this status, can customize according to demand included ply angles non-twist fibre reinforced prepreg.
Description
Technical field
The invention belongs to the productions of fibre-reinforced high molecular material processing technique field, especially carbon fiber prepreg to set
It is standby.
Background technique
Carbon fiber belongs to high performance fibre material, its excellent properties are widely approved.Its density ratio aluminium
Low, specific strength is compared with steel height.Under normal conditions, the tensile strength of the carbon fiber used in the composite be all 3.5GPa with
On, stretch modulus is also in 20GPa or more.In addition to the significant advantage on mechanical strength, fatigue durability, thermal expansion coefficient is low, resistance to
The performances such as corrosion are but also carbon fiber occurs in more and more applications.
The processing method of carbon fibre composite be also it is varied, be made into carbon fiber prepreg carry out again it is subsequent
Hot-forming is one of current prevailing technology, and maturity is also higher with market acceptance.However the non-twist carbon fiber of current global general-use
Dimension prepreg is unidirectional pre-immersion material, the prepreg in as 90 degree directions.Since final product usually requires in a plurality of directions
Reach mechanics demand, therefore need before composite article is made to design laying angle according to product performance demands, laying quantity with
And overlay thickness, complicated artificial laying process is carried out, this easily leads to the unstable of the accuracy of carbon fiber angular distribution, directly
Connecing causes final product performance unstable, and yields is insufficient.Artificial laying, which also limits production efficiency and increases, to be produced into
This.Polyaxial mechanical laying disclosed in this invention is integrally formed mode and revolutionizes this status, can determine according to demand
System has included the prepreg of the non-twist fibre reinforced of ply angles.
Summary of the invention
Now given an example with the production method of ± 45o biaxially carbon fiber prepreg.The biaxially carbon fiber prepreg
Equipment include that 1-1 spindle room, 1-2 sizing groove, 1-3 baking oven, 1-4 briquetting device, 1-5 cutter device, 1-6 mechanical traction are set
Standby, 2-1 spindle room, 2-2 sizing groove, 2-3 baking oven, 2-4 briquetting device, 2-5 cutter device, 2-6 mechanical traction equipment, 3 crawler belts
Formula briquetting device, 4 lower release paper unwinding equipments, 5 adhesive printing devices, 6 adhesive printing devices, release paper leads out dress on 7
It sets, 8 assist moulding and upper release paper collection apparatus, 9 surface protection film unwinding equipments, 10 prepreg wrap-ups.Carbon fiber from
Enter sizing groove 1-2 in spindle room 1-1 to be surface-treated, subsequently enters baking oven 1-3 drying, then pass through briquetting device 1-4.
When carbon fiber is drawn by 1-4 to the position 1-6 by mechanical traction device 1-6, briquetting 1-4 is pushed, in addition crawler type
Two pieces of briquettings of the correspondence width on briquetting device 3 push, and then general who has surrendered's carbon fiber is cut off under the blade in cutter device 1-5,
Blade rises, and crawler belt travels forward the distance of a stent width immediately, and mechanical traction equipment 1-6, which is moved at briquetting 1-4, to be stung
The carbon fiber breakpoint cut is shared, above procedure is repeated.
When unidirectional fibre laying and lower release paper pass through adhesive printing device 5, automatic multiple spot gluing will do it, with
Carbon fiber laying is fixed on lower release paper surface.
When unidirectional fibre laying and lower release paper reach a point, corresponding crawler type briquetting release rises to highest point, when
When reaching b point, corresponding briquetting declines and switches briquetting, and to adapt to next laying direction, switching work is completed when reaching c point
Sequence.
Second layer laying is identical as the principle of first layer laying.Completed laying is adhered to by upper release paper 7, then by auxiliary
Pressing aid adhesive dispenser 8 carries out moulding infiltration, and upper release paper is wound, then carries out upper surface by 9 unwinding equipment of surface protection film
Protective film fitting finally enters the winding of wrap-up 10.
Can add one or more groups of laying units in above production procedure, laying unit include spindle room, sizing groove,
Baking oven, briquetting device, cutter device, mechanical traction equipment and the adhesive printing on main laying track (0 degree of direction) are set
It is standby.
