Abstract

The utility model relates to a multidirectional knitting fibre composite material, which comprises a pipe-shaped net body with a hollow circular diameter. The pipe-shaped net body is formed by the method that a plurality of fibre bundles are overlapped and knitted with molding objects at a predetermined angle by matching with the desired strength characteristic of the molding objects, wherein the inner diameter of the pipe-shaped net body is axially and integrally knitted into a middle spacing net surface. The middle spacing net surface is parallel to the shaft center of the pipe-shaped net body, and both end sides of the middle spacing net surface are connected with net surfaces at the periphery of the pipe-shaped net body. Therefore, the middle spacing net surface can hamper and reduce the displacement and the deformation of the overlapping angles of the fibre bundles in the molding process, thereby, the molding quality and molding strength of composite material fibre members can be improved.

Description

Multidirectional woven fiber material

The utility model relates to the multiple equipment structure of fiber, refers to a kind of multidirectional woven fiber material especially.

The multiple equipment structure of fiber known to previous, owing to have the characteristic of light weight, and be widely used in various products with pipe fitting, such as racquet frame, club, fishing rod, bicycle rack or the like.The multiple equipment structure of the fiber of known widely utilization as shown in Figure 1, 2, be broadly divided into two kinds: the multiple equipment structure of a kind of fiber is to utilize the fiber winding back of different angles to cooperate resin to soak into a fiber weavening plate earlier, as shown in Figure 1, according to desiring the moulding pipe fitting aforementioned fibers textile board is suitably cut coiling and molding then, because operating winding layer by layer, multiple material wasting phenomenon easily takes place in its reinforcement process, and easily causes the thick and heavy shortcoming of finished product; Therefore, the multiple equipment structure of second kind of fiber shown in Figure 2 is arranged again, it directly takes plural fibre bundle to cooperate resisting of desire moulding pipe fitting to open or torsion strength calculates the due angle that interweaves of its fiber formation, be woven into the cast guiding principle body of required circle footpath hollow then with multidirectional plural fibre bundle, on the surface, as if quite can eliminate aforementioned first kind and commonly use the thick and heavy shortcoming of structure finished product; And in actual forming operation process; because the cast guiding principle body that plural fibre bundle was woven into is soft state; must cooperate the axle of a gas tube bag to establish inflation support migration mould molding; the angular shift distortion that interweaves that fibre bundle is shaped originally takes place in regular meeting in moving; so that the moulding quality of going into behind the mould is bad, anti-ideal that reaches the structural strength of torsion not as expection.

Main purpose of the present utility model promptly will provide a kind of multidirectional woven fiber material that lowers the displacement distortion of fibre bundle in the operating process of multiple material molding component, and can promote quality and anti-, the torsion strength of moulding.

For reaching above-mentioned purpose, the multidirectional woven fiber material that the utility model adopted comprises the cast guiding principle body in hollow circle footpath, and this cast guiding principle body is overlapped at a predetermined angle to weave by fibre bundle cooperation shaped article desirable strength characteristic and constitutes; Wherein, the bore axes of this cast guiding principle body every the guiding principle face, be parallel to the axle center of cast guiding principle body in this every the guiding principle face, and the guiding principle face of its both end sides and cast guiding principle body circumference is connected in one braiding one.

Every between two guiding principle faces of guiding principle face, press from both sides the elastic sheet of establishing a tool vibration absorptive material in described.

After adopting said structure, can pin down the fibre bundle overlapping angle of cast guiding principle body periphery in of the present utility model every the guiding principle face, cast guiding principle axon makes to be difficult in the formed in mould operating process of its migration producing the displacement distortion, even also can reduce moving of overlapping angle effectively when the inflation pressurising; Therefore, the object of institute's moulding not only has light weight and the splendid effect of surperficial tensile strength, also has stronger twisting resistance performance simultaneously, thereby improves the quality and the intensity of multiple material fibrous structures moulding.

Below in conjunction with drawings and Examples the utility model is done further detailed description.

Fig. 1 is the multiple material schematic diagram of known fiber;

Fig. 2 is known multidirectional woven fiber material schematic diagram;

Fig. 3 is the partial sectional perspective view of the utility model one preferred embodiment;

Fig. 4 is the transverse sectional view of structure shown in Figure 3;

Fig. 5 cooperates radial cross-section after the shake avoiding body installing for the utility model.

At first, see also shown in Fig. 3,4, multidirectional woven fiber material described in the utility model comprise a cast guiding principle body 10 and by these cast guiding principle body 10 bore axes establish two in every guiding principle face 20, wherein:

Cast guiding principle body 10 roughly is the cannula-like of a hollow, mainly by the fibre bundle more than two strands 11 common cooperate constitute strength characteristics that institute desires shaped article at a predetermined angle α, β overlapping weave and constitute, as shown in Figure 3, this fibre bundle 11 successively in regular turn by set angle around its central axis 12 with clockwise or before the rotation counterclockwise and then be woven into one and seal circumference 13, make its fibre bundle 11 that overlaps braiding up and down be configured to the elastic force guiding principle 14 of a continuous shape, thereby the tensile strength of the circumferential surface after the object moulding is provided;

In every the central axis 12 parallel foundation of guiding principle face 20 (as shown in Figure 4) with cast guiding principle body 10, taking the center of aligning to be arranged in parallel into the two sides in the present embodiment forms, its be equally by the fibre bundle more than two strands 21 common cooperate constitute desire the strength characteristics of shaped article, and α at a predetermined angle, β overlaps to weave and forms, as shown in analysing and observe partly as Fig. 3, its fibre bundle 21 shuttles back and forth to weave by the set angle intersection in regular turn successively and forms a plane guiding principle shape, and its vertical side 22 two ends are connected with the guiding principle face of the sealing circumference 13 of cast guiding principle body 10 respectively, can borrow vertical side 22 two end supports and limit sealing circumference 13 mutually, still can keep being difficult for the state of migration under the action that the angle that elastic force guiding principle 14 circumference are interweaved supports out outside; In addition, axle establish two in the middle of guiding principle face 20, can increase by a tool vibration absorptive material elastic sheets 23 folders establish and be adjacent to fixingly, as shown in Figure 5, and form a sandwich main beam structure, can increase best in the axial direction shock-absorbing performance behind the component forming.

In sum as can be known, in pin down the fibre bundle overlapping angle of cast guiding principle body 10 peripheries every guiding principle face 20, make it to be difficult in the formed in mould operating process of migration producing the displacement distortion; As shown in Figure 4, even cast guiding principle body 10 also can reduce moving of overlapping angle effectively when axially inflating pressurising; Therefore, can obtain a more known more superior moulding quality after the object moulding sclerosis, reduce under the situation that walks in fibre bundle overlapping angle, the object of institute's moulding not only has light weight and the splendid effect of surperficial tensile strength, simultaneously also because of cast guiding principle body 10 be provided with in axially in after guiding principle face 20 makes its moulding axially general known twisting resistance performance stronger, thereby more help the picture golf clubs, classes such as baseball need the product development of strong torsion design, lower the displacement distortion of fibre bundle overlapping angle in the forming process, improve the quality and the intensity of multiple material fibrous structures moulding.
