Abstract
The utility model relates to a specific admixture 3D woven preform, comprises two kinds of different types of yarns, and described two kinds of different types of yarn braidings form prefabricated component, and described two kinds of different types of yarns mix evenly and distributional stability in prefabricated component cross section.The utility model does not need to prepare blended yarn, has reduced operation, simple to operate, is conducive to reduce production costs; In prefabricated component cross section, variety classes Yarn homogeneous, stable distribution, make prefabricated component performance even.
Description
Technical field
The utility model relates to 3D woven preform technical field, particularly relate to a kind of being formed by two kinds of variety classes yarns braidings, two kinds of yarns in prefabricated component cross section, mix evenly and distributional stability mix 3D woven preform.
Background technology
Cost degradation, multifunction that to mix 3D woven preform be composite provide an important channel, and have retained the shock resistance, endurance of 3D braided structure, many excellent properties such as not stratified; These characteristics makes to mix 3D woven preform in field extensive application such as Aero-Space, defence and military and automobiles.
At present, mixing 3D woven preform mainly hangs yarn by the grouping of fiber hybrid in yarn and spindle and mixes these two kinds of methods and prepare.In yarn, in fiber hybrid method, different types of fiber hybrid need to be made to blended yarn, cause mixing 3D woven preform production cost too high; Spindle grouping is hung in yarn mixing method, and different yarns is skewness, unstable on prefabricated component cross section, causes mixing 3D woven preform and has performance deficiency.Above-mentioned factor has restricted the extensive use that mixes 3D woven composite.
Utility model content
Technical problem to be solved in the utility model is to provide a specific admixture 3D woven preform, does not need in the preparation different fiber hybrids to make blended yarn, has reduced operation, has reduced production cost, has avoided performance deficiency simultaneously.
The utility model solves the technical scheme that its technical problem adopts: a specific admixture 3D woven preform is provided, comprise two kinds of different types of yarns, described two kinds of different types of yarn braidings form prefabricated component, and described two kinds of different types of yarns mix evenly and distributional stability in prefabricated component cross section.
On the line direction of described prefabricated component cross section, formed by described two kinds of different types of yarn alternative arrangements.
On the column direction of described prefabricated component cross section, formed by described two kinds of different types of yarn alternative arrangements.
Beneficial effect
Owing to having adopted above-mentioned technical scheme, the utility model compared with prior art, has following advantage and good effect: the utility model does not need to prepare blended yarn, has reduced operation, simple to operate, is conducive to reduce production costs.Variety classes Yarn homogeneous, stable distribution in prefabricated component cross section in the utility model, prefabricated component performance is even.The utility model is all applicable to the various forms of knitting yarns such as single thread, strand, and is not subject to the restriction of prefabricated component shape of cross section, applied widely.

Detailed description of the invention
Below in conjunction with specific embodiment, further set forth the utility model.Should be understood that these embodiment are only not used in restriction scope of the present utility model for the utility model is described.In addition should be understood that those skilled in the art can make various changes or modifications the utility model after having read the content of the utility model instruction, these equivalent form of values fall within the application's appended claims limited range equally.
Embodiment of the present utility model relates to a specific admixture 3D woven preform, comprise two kinds of different types of yarns, described two kinds of different types of yarn braidings form prefabricated component, and described two kinds of different types of yarns mix evenly and distributional stability in prefabricated component cross section.Wherein, mix and evenly refer to that two kinds of different types of Yarn homogeneous mix, such as, on the line direction of prefabricated component cross section, formed by described two kinds of different types of yarn alternative arrangements, on the column direction of prefabricated component cross section, formed by described two kinds of different types of yarn alternative arrangements; Distributional stability refers to through after an arbitrary integer machine cycles, and the yarn in prefabricated component cross section distributes and remains unchanged completely.
Further illustrate the utility model with two specific embodiments below.
Embodiment 1:
As shown in Figure 1, be the cross sectional representation of the present utility model under square weaving, in figure, prefabricated component is formed by yarn 1 and 2 two kinds of yarn braidings of yarn.Yarn 1 and yarn 2 mixing in prefabricated component cross section are completely uniformly, are alternative arrangements walking crosswise yarn 1 and yarn 2 in direction, and in file direction, yarn 1 and yarn 2 are also alternative arrangements.The distribution of 2 two kinds of yarns of yarn 1 and yarn in prefabricated component cross section is metastable, and after an arbitrary integer machine cycles, the yarn in prefabricated component cross section A, B, C distributes and remains unchanged completely, sees Figure 1A-Fig. 1 C.
Embodiment 2:
As shown in Figure 2, be the cross sectional representation of the present utility model under tubular braiding technique, in figure, prefabricated component is formed by yarn 1 and 2 two kinds of yarn braidings of yarn.Yarn 1 and yarn 2 mixing in prefabricated component cross section are that in peripheral traveling direction, yarn 1 and yarn 2 are alternative arrangements completely uniformly, and in radial alignment direction, yarn 1 and yarn 2 are also alternative arrangements.Yarn 1 and the distribution of yarn 2 in prefabricated component cross section are metastable, and after an arbitrary integer machine cycles, the yarn in prefabricated component cross section A, B, C distributes and remains unchanged completely, sees Fig. 2 A-Fig. 2 C.
The utility model does not need to prepare blended yarn, has reduced operation, simple to operate, is conducive to reduce production costs; In prefabricated component cross section, variety classes Yarn homogeneous, stable distribution, make prefabricated component performance even; All applicable to the various forms of knitting yarns such as single thread, strand, and be not subject to the restriction of prefabricated component shape of cross section, applied widely.
