Specific embodiment
Specific embodiment of the utility model is described further below in conjunction with attached drawing.
As shown in Figure 1, carbon fibre composite cabin provided in this embodiment is mainly by top cover 1, left-side 2, right side wall
3, front wall 4, back wall 5, preceding floor 6, rear floor 7 and parcel shelf 8 form, these described components are by carbon fibre composite system
At can specifically pass through RTM technique and carry out formed product by the structure glue sticking composition cabin.
Top cover 1, left-side 2, right side wall 3, front wall 4, back wall 5, preceding floor 6, rear floor 7 and the parcel shelf 8 is needing
The position to be bonded is equipped with bonded edge S, and the width of bonded edge S is 20mm ~ 40mm, and bonded edge is carried out between part
The glue bearing areas of bonding.For the bonded edge S, Fig. 2 using left-side 2 as illustrating.In the bonded edge S
On be equipped with round resin boss T, it is highly 0.5mm ~ 2mm that diameter, which is 10mm ~ 15mm, is carried out along the path of bonded edge S
Arrangement, is divided into 100mm ~ 200mm.Resin boss T is to control bondline thickness, the entirety of cooperation bonding jig control product
Size.It is chosen in size described above when specific implementation according to the practical structures of product and shape.The resin
Boss T can be by the cavity of correspondingly-sized reserved on mold, and under RTM technique, resin fills cavity, is formed after curing molding
Required resin boss T.
The bonding sequence of the cabin is as shown in Figure 5.
The top cover, left-side, right side wall, front wall, back wall, preceding floor, rear floor and parcel shelf surfaces externally and internally layer
Using carbon fiber twills, middle layer uses one-way tape and bi-axial fabric.
The modulus of shearing of carbon fibre composite adhering components structure glue is 100MPa ~ 200MPa in the cabin；
In the cabin carbon fibre composite component it is bonding with metal parts with the modulus of shearing of structure glue be 400MPa ~
700MPa.The structure glue of low modulus between carbon fibre composite component for being bonded, and bring is answered when reducing clamping bonding
Power；The structure glue of high-modulus is for bonding between carbon fibre composite component and metal parts, to guarantee to be installed on metal
The rigidity and position degree of part in portion.
It is illustrated below for the details of side wall 2 and preceding floor 6.
1, as shown in Figures 2 and 3, side wall is illustrated by taking left-side 2 as an example.The left-side 2 by left-side outside
Plate 21, left-side inner panel 22 and revolver hood panel 23 are bonded, and the integrated molding of RTM technique respectively can be used.By integrated
The mode of design takes the strategy of not uniform thickness laying that number of parts is greatly decreased, and assembly efficiency is improved.The side
It encloses after outside plate 21 and side-wall inner-plate 22 are bonded and is respectively formed cavity body structure at A column, B column, C column, side wall top and side threshold,
Such cavity body structure has high rigidity, has great promotion for the bending rigidity and crashworthiness of cabin.Left side
The rear portion for enclosing 2 inner panels 22 is integrated with the function of wheel cover inner panel, forms cover portion structure with revolver hood panel 23.Being will be traditional
Wheel cover inner panel is integrated in side-wall inner-plate, optimizes design of part, reduces number of parts.Described in the left-side
2 are in U-shape equipped with the sections of A column reinforcement plate J1 and B column reinforcement plate J2, A column reinforcement plate J1 and B column reinforcement plate J2, whole shape face with
A column and B column inner cavity shape the face paste merging of left-side 2 are bonded.Pass through the compound of metal reinforcing plates and carbon fibre composite
Using realization local reinforcement, so that having higher safety in terms of side impact.By taking left-side inner panel 22 as an example, laying is taken
Area P is met to be illustrated.As shown in Fig. 2, there is laying overlap P everywhere on left-side inner panel 22, it is distributed in side wall roof side rail and side
Enclose the junction of threshold Yu A column and B column.Laying overlap while is obtained in cross-connecting area higher to optimize lay-up process
Intensity.Laying overlap P belongs to the public domain of junction in laying, when specific operation, to B column and side threshold subregion
Laying will be mutually staggered in the laying of laying overlap P.For this base part of side wall, substantially by side wall roof side rail, side wall door
The almost plane frame structure of sill, A column, B column and C column composition is primary load bearing direction in respective length direction, therefore laying is set
The orientation needs of timing fiber are consistent to the full extent with length direction, therefore laying overlap need to be arranged in junction.
2, as shown in figure 3, the preceding floor 6, which is, can be used the integrated molding of RTM technique, border is to upper overturning；Wherein
Left and right sides flange is completely coincident, so that it is in basin that preceding floor 6 is whole to the upper surface of side threshold with the medial surface of side threshold
Shape structure.Kind bathtub construction has preferable dimensional stability, for anisotropic composite material, very big journey
The buckling deformation avoided after product depanning on degree；Bathtub construction can also assign product excellent rigidity simultaneously.Such as Fig. 4 institute
Show, seat beam M uses sandwich in preceding floor 6, includes sandwich core material 61 and the fixed spiral shell of seat in the sandwich
Motherboard 62.The sandwich core material 61 uses rigid foam, material can for PET, PMI, PVC etc., apparent density be 100kg/m3 ~
200kg/m3.Seat fixture nut plate 62 and sandwich core material 61 carry out pre-glued, and then laying carries out one in specified laying
Molding.Such integrally formed interlayer scheme makes the light weight effect on preceding floor 6 obvious, while in the stiffness and strength of product
The performance of aspect is all more prominent.
Before above each adhering components, by the determination of Interference Check and assembly relation, first by carbon fiber component
On metalwork and standard component be bonded and installed.It is different according to the force request of metalwork, added using pure riveting and riveting
The mode of bonding.For the screw bolt and nut in cabin, using pulling rivet bolt L1 and rivet nut L2.
The bending stiffness of manufactured carbon fibre composite cabin reaches 12000N/mm, torsion stiffness through the above scheme
Reach 8000Nm/ °, first-order flexure mode reaches 70Hz, and single order torsion mode reaches 50Hz.
It is described in detail above in relation to one embodiment of the utility model, but this item utility model is technical
Range is not limited to the contents of the specification, the equivalent embodiments or change that all technical characterstics according to the present utility model carry out
More, it should be included within the scope of protection of this utility model.
