Background technique
The moulding process of traditional long fiber reinforcement composite pipe take directly with metal core die or bulging die or Air bag auxiliary is closed the forming method of rigid former, and each fiber laying is the structure type of complete laying.
The moulding process of traditional long fiber reinforcement composite pipe take directly with metal core die or bulging die or Air bag auxiliary is closed the forming method of rigid former, because composite structure forming process is compaction process, no matter uses Which kind of technique long fiber reinforcement forming composite pipe method all suffers from fiber laying and moves in thickness direction, herein mistake Due to the long stapled restraining function of not 0 deg direction laying in journey, it is easy in forming process that fiber arch formation easily occurs, and Lead to the mass defects such as layering and the cavity of final products, drastically influences the Forming Quality of long fiber reinforcement composite pipe With manufacture efficiency.
Summary of the invention
The purpose of the present invention is to propose to a kind of method of manufacturing technology of long fiber reinforcement composite pipe, are effectively reduced very To fiber-wound pressure vessels defect is eliminated, the Forming Quality and manufacture efficiency of long fiber reinforcement composite pipe are promoted.
The technical solution of the invention is as follows, (1) according to long fiber reinforcement composite pipe structure to be prepared and Ply angles form determines the total quantity M and total number of plies N of not 0 deg direction laying, and not 0 deg direction laying is cut using 0 ° of direction, Total number of plies N≤M；
(2) according to the ply stacking-sequence of ply angles, the not 0 deg direction laying of 0 ° of direction docking paving will be used to number as N1、 N2…Nn；Wherein, n=1,2 ..., two banjo fixing butt jointings are all made of on every layer, and two banjo fixing butt jointings are 180 ° on the circumference of cross section Relatively, the radian angle of the banjo fixing butt jointing in adjacent laying is α；
(3) it according to long fiber reinforcement composite pipe ply angles form, determines and each of paving is docked using 0 ° of direction The banjo fixing butt jointing position of not 0 deg direction laying carries out the paving of long fiber reinforcement composite pipe on expanded rubber core model；
(4) closed profiles mould, and after cured, die sinking process, prepare long fiber reinforcement composite pipe.
Total number of plies N >=1 of not 0 deg direction laying of 0 ° of direction docking paving of use.
Meet between radian angle α corresponding to the adjacent banjo fixing butt jointing and total number of plies N: α=180 °/N.
The N1、N2…NnRadian angle corresponding to middle any two number layer y, x is α satisfaction: α=︱ y-x ︱ × 180 °/N or α=180 °-(︱ × 180 ° ︱ y-x)/N.
The present invention has the advantage that and beneficial effect,
The prepreg overlay at least one not 0 deg direction of the invention uses 0 ° of direction prepreg and docks paving mode, in advance Leaching material docking paving mode enhances each laying internal activity and coordinates performance, and the constraint that prepreg slides at the time of molding is solved Put, can effectively reduce and even be eliminated fiber-wound pressure vessels defect, effectively promoted long fiber reinforcement composite pipe Forming Quality with Manufacture efficiency.Meanwhile present invention is alternatively directed to prepreg overlay banjo fixing butt jointings to have carried out homogenizing distribution setting, this aspect reinforcement Whole interior coordination of action performance when formation of tubes obtains good Forming Quality, while also having taken into account the whole high of pipe fitting Intensity requirement.
Detailed description of the invention
Fig. 1 is ply angles schematic diagram of the invention.
Specific embodiment
(1) according to long fiber reinforcement composite pipe structure and ply angles form to be prepared, not 0 deg side is determined To the total quantity M and total number of plies N of laying, not 0 deg direction laying is cut using 0 ° of direction, total number of plies N≤M, and total number of plies N >= 1；
(2) according to the ply stacking-sequence of ply angles, the not 0 deg direction laying of 0 ° of direction docking paving will be used to number as N1、 N2…Nn；Wherein, n=1,2 ..., two banjo fixing butt jointings are all made of on every layer, and two banjo fixing butt jointings are 180 ° on the circumference of cross section Relatively, the radian angle of the banjo fixing butt jointing in adjacent laying is α, α=180 °/N, and the N1、N2…NnIn any two Radian angle corresponding to a number layer y, x is that α meets: ︱ × 180 ° α=︱ y-x/N or α=180 °-(︱ × 180 ° ︱ y-x)/ N；
(3) it according to long fiber reinforcement composite pipe ply angles form, determines and each of paving is docked using 0 ° of direction The banjo fixing butt jointing position of not 0 deg direction laying carries out the paving of long fiber reinforcement composite pipe on expanded rubber core model；
(4) closed profiles mould, and after cured, die sinking process, prepare long fiber reinforcement composite pipe.
Embodiment 1: factory length 1500mm, outer diameter 50mm, wall thickness are the carbon fiber round tube of 2.5mm.Using upper and lower The former of mould composition, mold material are ordinary carbon steel, die length 1500mm, die cavity diameter 50mm after upper and lower mould molding, mould The design of tool both ends has plug；Core model long stick made of expansion silicon rubber, core model length be 1500mm, silicon rubber bar core it is general Lead to carbon steel pole to keep the straightness of core model, ordinary carbon steel diameter of the rod about 10mm, core model diameter is 450.5-1.0mm.It adopts Use 3234/G803 plain weave carbon fiber cloth middle-temperature solidifying epoxy pre-dipping material as pipe inner and outer surface layers, monolayer immobilization thickness 0.20mm, Middle layer is 3234/T300 unidirectional carbon fiber middle-temperature solidifying epoxy pre-dipping material, and monolayer immobilization is with a thickness of 0.125mm.Laying side Formula be [45 ° of cloth/0 °/45 °/- 45 °/0 °/0 °/- 45 °/45 °/0 °/90 °/0 °/45 °/- 45 °/0 °/0 °/- 45 °/45 °/0 °/ 45 ° of cloth].Operating procedure is as follows: 1) calculating offset angular.Including carbon cloth prepreg and unidirectionally in the design laying of this tubing Carbon fiber prepreg material removes 0 ° of direction laying of unidirectional carbon fiber prepreg, other laying sums are 10, therefore offset angular α =180 °/N=18 °；2) staggered positions line is symmetrically marked in pairs every 18 ° in the rear and front end of core model head；3) prepreg Cutting.Calculate separately the circular diameter of each layer, wherein it is 1500mm that the size of 0 ° of each layer of unidirectional pre-immersion material, which is length, width according to The difference of the circular diameter Φ n of each layer is π Φ n, other 10 each layings in other directions need to cut 2, every having a size of, Length is 1500mm, and width is π Φ n/2 according to the difference of the circular diameter Φ n of each layer；4) paving prepreg.According to the paving of design Layer sequence, carries out paving on core model, wherein 0 ° of unidirectional pre-immersion material layer, is directly coated with one, the laying in other paving directions, The offset angular line symmetrically marked by both ends carries out docking and is coated with, and docking location is directed at the marking line at both ends, other next pavings The laying in direction is pasted, then rotates 18 ° of offset angular marking line at same direction and is used as docking paving position, until completing all Paving；5) molding solidification.The core model of completion paving prepreg is fitted into shape mold, upper and lower mould is closed and tightens bolt, The plug block at both ends is locked again.It moves in drying chamber, takes out and be opened after solidifying 2 hours at 125 DEG C, obtain carbon after deviating from core model Fibrous composite round tube product.The mass defects such as layering, stomata are not found through ultrasonic non-destructive inspection.
