Description
Technical field
The invention belongs to field of compound material, it is related to a kind of box-like stereo fabric and its coupling method for weaving, specifically
A kind of more structure Coupling integral weaving methods of the box-like stereo fabric of composite material.
Background technique
There are many structural member of cassette shapes in spacecraft flight device and aviation field, operating condition and environment are extremely
Strictly, it does not require nothing more than that quality is small, interlayer performance is good, and should also have the Functional Requirements such as solar heat protection, wave transparent, anti-ablation.
For the fiber orientation of different braiding structures with each to proportion of fibers difference, single structure realizes that large scale is capacity of equipment
With the expansion of process capability, but different structure coupling be related to the variation in number of yarns and direction, it is ensured that yarn is in different knots
Continuous transition between structure, the yarn needed to establish between the yarn model of single structure and coupled structure integrate conversion rule, it then follows yarn
The continuous principle of line, otherwise will appear transition position yarn lines disorder, and fiber is discontinuous so that the stress in performance is caused to concentrate,
It is easy to produce destruction.
Different structure coupling condition usually has more than one component principal direction, to consider to weave principal direction in weaving process
Conversion to realize member profile, the conversion of weaving direction is related to the conversion of yarn direction, need to consider yarn tension, squeeze
The influence that deformability changes direction, fiber volume fraction wants uniformity while keeping yarn continuous, will not cause density
Non-uniform phenomenon.
In order to all meet the application requirement of box body from technique and aspect of performance, different weavings is used at different positions
Method meets the requirement of box body structure part.The bottom of box body uses 2.5D structure, and box wall uses three-dimensional braided structure.Cassette bottom
It using 2.5D structure, is not only easily achieved in technique, but also can guarantee the power of box-like fabric bottom through broadwise yarns interwoven
Performance is learned, and weaving efficiency is high；Box wall uses three-dimensional braided structure, and three-dimensional braided structure is easily achieved profiling weaving, can
The right angle feature of box wall is molded well, while yarn forms netted pilotaxitic texture in space, it is broken that side wall is not likely to produce layering
It is bad, have many advantages, such as good integrity, good mechanical performance.Therefore, the coupling weaving of two kinds of three dimensional fabric structures can sufficiently be sent out
The characteristics of waving each self-structure, synergistic effect, good integrity and performance are stablized, and operability significantly improves, and performance is surveyed after compound
Examination box body mechanical property fully meets design objective requirement.The coupling method for weaving can realize the shape of Large Size Special Shaped structural member
Profiling is applied to primary load bearing component for three dimension stereo fabric composite material and provides wide prospect.
Summary of the invention
It is an object of the invention to overcome the defect of existing single textile technology, kind of box-like stereo fabric and its a coupling are provided
Method for weaving prepares high-performance fiber (quartz fibre, carbon fiber etc.) box body structure part using the method for weaving, according to box body
Performance requirement and process use different weaving technologies at different positions as needed, by combination process, Ke Yiman
Requirement of the sufficient composite element different parts to performance, appearance, uniformity.
The present invention includes following technical solution：
A kind of box-like stereo fabric, including cassette bottom and box wall, it is characterised in that the cassette bottom is 2.5D structure, the box wall
For three-dimensional braided structure, the box-like stereo fabric is integrally formed using coupling method for weaving.
Preferably, the cassette bottom of the box-like stereo fabric be 2.5D structure, be specifically as follows 2.5D Angular interlocking structure,
2.5D laying-in Angular interlocking structure, 2.5D inlaid thread Angular interlocking structure or 2.5D laying-in inlaid thread Angular interlocking structure.
Preferably, the box wall of the box-like stereo fabric is three-dimensional braided structure, is specifically as follows three-dimensional four-way, three-dimensional
Five-way, three-dimensional six-way or three-dimensional seven-way structure.
Preferably, the box-like stereo fabric cassette bottom shape is the side n shape (n >=3), circle, ellipse or irregular shape
Shape.
A kind of more structure Coupling method for weaving of box-like stereo fabric, which is characterized in that include the following steps：
1) according to the design requirement of cassette bottom fabric, from 2.5D Angular interlocking structure, 2.5D laying-in Angular interlocking structure, 2.5D inlaid thread
The braiding structure of product is chosen in Angular interlocking structure or 2.5D laying-in inlaid thread Angular interlocking structure, and according to the size of box body, fiber
The position of the warp thread number of plies and columns needed for the requirements such as volume content, longitude and latitude yarn density calculate cassette bottom and beginning and end wefting insertion
It sets, furthermore, it is necessary to design the length of yarn for reserving braiding box wall.
2) designed warp thread is hung on 2.5D loom, harness motion, introduce weft yarn (using single wefting insertion method,
Designed weft yarn is successively introduced into thread layer, the reserved yarn at weft yarn both ends stays in the outside of fabric), secondary harness motion,
Secondary introducing weft yarn；
3) repetitive cycling operates according to the method described above, until cassette bottom completes weaving；
4) before weaving box wall, the vertical center for being fixed on weaving unit unit of the braiding core model of processing is centainly high
At degree；
5) cassette bottom fabric is removed from 2.5D loom, fabric is placed at the top of braiding core model, core model is completely covered.According to
Box wall size and the three-dimensional braided structure of selection design knitting yarn ranks number carry out row's yarn, using reserved warp thread and weft yarn as box
The 3 D weaving yarn of wall is connected with three dimensional knitting machine.If there is thickness or change in size etc., it is also necessary to plus-minus yarn operation is carried out,
Increase and decrease fineness by yarn, yarn plying and increase and decrease yarn ranks number realize the transition from cassette bottom to box wall；
6) after knitting yarn sequences, the braiding of box wall, step 1 are carried out according to 3 D weaving four step braiding method：It is adjacent
The mobile position of row knitting yarn alternating；Step 2：The mobile position of adjacent column knitting yarn alternating；Step 3 and step 4：Braiding
The direction of motion of yarn is opposite with step 1 and step 2 respectively.During box wall braiding, as the variation of box body perimeter will connect
Continuous uniform increase and decrease knitting yarn is to guarantee to spend the consistent of byte wide.
7) repetitive cycling operates according to the method described above, until box wall completes braiding.
Compared with existing box body fabric knitting technology, the advantages of present invention has and good effect：
The present invention can be realized two kinds of fabric construction seamless connections.
Fabric coupling method for weaving provided by the invention is artificially to divide box body there are two types of on the basis of fabric construction existing
For two parts, yarn is different in the movement of the box body different parts rule that interweaves, and the yarn in fabric be it is totally continuous, pass through
Yarn is rearranged and increased and decreased to yarn, the coupling seamless connection of two kinds of three-dimensional structures is realized from structure.
Fabric construction can be designed according to the performance requirement of composite material, realization derivative structure (including 2.5D laying-in
