Abstract

The utility model discloses a three-dimensional fabric capable of being lengthened horizontally and longitudinally, belonging to the technical field of textile, and solves the weaving problem of the three-dimensional fabric. The three-dimensional fabric adopts the technical scheme that the three-dimensional fabric comprises a plurality of layers of fabric which is formed by a plurality of waveform fabric mutually interlaced together, and the longitudinal section is diamond mesh-shaped. Each waveform fabric consists of a warp yarn and a weft yarn which are interlaced; and the relationship between the upper and lower is changed when any two waveform fabric are interlaced. In the utility model, the thickness and the length can be adjusted in a larger range, the generality is strong, and the fabric is particularly applicable to fabricate the plate-type composite material reinforcement; in addition, as the three-dimensional fabric is only provided with the warp yarn and the weft yarn, the three-dimensional fabric can be weaved by the common two-dimensional loom, the production cost is low, and the fabric is helpful for large area application.

Description

Stereo fabric that can horizontal and vertical elongation

Technical field

It is the geometric stereo fabric of cyclically-varying that the utility model relates to the woven longitudinal section of a kind of available ordinary loom, belongs to textile technology field.

Background technology

The longitudinal section is that the geometric stereo fabric of cyclically-varying is a newcomer in the composite material reinforcement body field (field of textiles), it is light and thick, extending space is very big, whole connectivity is good, fill processing through resin and can form the very high composite of intensity, good mechanical performances such as tension pressure, shock resistance and anti-interlayer shear are arranged, be easy to physics, the chemical property of product are further enhanced and improve by technological means such as new material, chemical finishings.It is defeated a force with a tenderness, and with textile material substituted metal and Xylonite goods, can be widely used as the industry profile in the fields such as Aero-Space, building, fishery, medical treatment, military affairs, automobile.

In the longitudinal section is in the geometric stereo fabric of cyclically-varying, and the someone weaves out hollow plates such as the solid sheet material peace of multilayer lamina is inline, orifice plate, and also existing people relates to as shape fabrics such as orthohexagonal honeycomb boards.These stereo fabrics are different from two dimensional surface composite bed fabric fully, the latter gets up to form multiply cloth to the bondings such as the plane fabrics used resin of individual layer that become by warp and weft interweaving, its interlaminar shear strength is lower, and the former makes the warp and weft interweaving layer be interwoven between yarn or thread layer by hanging down.Hand over the orthohormbic structure multiply cloth or the multiply cloth of knot by exchanging between thread layer by the yarn that hangs down, all can make each layer be interconnected into overall structure, improve interlaminar shear strength, make fabric possess impact resistance good, be not prone to characteristics such as cracking delamination when bearing bending moment and vibration.

Just because of stereo fabric has above-mentioned advantage, it is all had a wide range of applications in every field.But because the general structure of stereo fabric is comparatively complicated, to having relatively high expectations of loom, need to adopt the three-dimensional loom of complex and expensive, or the special loom of process transformation such as many races loom etc. are weaved, cause weaving very inconvenient, production cost height, and the characteristics difference of every kind of fabric, purposes is single, versatility is relatively poor, be unfavorable for the research and development of stereo fabric new varieties, therefore, develop easily weave, the stereo fabric of highly versatile is the problem that textile technology field needs to be resolved hurrily.

Summary of the invention

Technical problem to be solved in the utility model provides and a kind ofly easily weaves, highly versatile can horizontal and vertical elongation stereo fabric.

Problem described in the utility model realizes with following technical proposals:

A kind of stereo fabric that can horizontal and vertical elongation, it is to be the multiply cloth of diamond-mesh by a plurality of waveform fabrics longitudinal section that forms that intersects each other, each waveform fabric is interwoven by warp thread and weft yarn.

Above-mentioned stereo fabric that can horizontal and vertical elongation, the number of plies of described waveform fabric is 2～9 layers.

Longitudinal section of the present utility model is a diamond-mesh, by changing the interior angle of rhombus, can be so that thickness of the present utility model increase, length reduces, its length is increased and thickness reduces, thereby can be used for making the board-like composite material reinforcement body of different-thickness and different length, versatility strengthens greatly.In addition, owing to have only warp thread and weft yarn in this stereo fabric, thereby can utilize common two-dimensional loom to weave, production cost is low, helps the promotion and application of this fabric.

Description of drawings

Below in conjunction with accompanying drawing the utility model is further specified.

Fig. 1 is a longitudinal section of the present utility model schematic diagram;

Fig. 2 is the flattening figure when weaving;

Fig. 3 is a looming draft.

Each label is among the figure: 1, warp thread, 2, weft yarn, a, b, c, d, e, waveform fabric numbering, a ₁～a ₁₀, knit the district after the flattening.

The specific embodiment

Referring to Fig. 1, the fabric longitudinal section is a diamond-mesh, and the waveform fabric that constitutes stereo fabric is of five storeys, and represents with a, b, c, d, e that respectively the warp thread of each waveform fabric is undulate all, weft yarn and warp thread weave in.Its diamond structure is to be interwoven by different layers warp thread alternatively up and down, because every layer of fabric interleaving degress is equal, does not have the warp run-in problem different with the amount of batching, and can weave continuously on new loom fully.

Referring to Fig. 2, the flattening figure of this fabric is divided into 10 and knits the district, respectively with a ₁～a ₁₀Expression, each is knitted and distinguishes five layers, represent with a, b, c, d, e respectively, when two-layer when crossing lower floor become the upper strata, upper strata change lower floor.As a ₁B is at the upper strata of c, a in the district ₂Middle b is in the lower floor of c.By that analogy, a ₁Distinguishing each floor order is a, b, c, d, e; a ₂Distinguishing each floor order is a, c, b, e, d; a ₃Distinguishing each floor order is c, a, e, b, d; a ₄Distinguishing each floor order is c, e, a, d, b; a ₅Distinguishing each floor order is e, c, d, a, b; a ₆Distinguishing each floor order is e, d, c, b, a; a ₇Distinguishing each floor order is d, e, b, c, a; a ₈Distinguishing each floor order is d, b, e, a, c; a ₉Distinguishing each floor order is b, d, a, e, c; a ₁₀Distinguishing each floor order is b, a, d, c, e.During looming weaving, the different layers fabric of respectively knitting the district is actually to be close to, and promptly thickness is very little.For for the purpose of visual, they have longitudinally been drawn back a segment distance among the figure.The order of weaving of every district weft yarn is that 1 to 5 latitude is followed successively by from top to bottom every layer first, and 6 to 10 latitudes are followed successively by from top to bottom every layer second.Shedding principle and multiply cloth are similar.

Fig. 3 is the looming draft when adopting the ordinary two dimensional loom to weave, and the upper left side is a drafting plan among the figure, and the lower left is an organization chart, and the lower right is a pegging plan.Reed draft is that every reed is worn two.
