Part of the body by quick -witted fabric layer in the prefabrication, the continuous fibers layer, and net plies stromatolite forms the elementary layer, sews up the shaping after a plurality of elementary layers combination acupuncture and is three -dimensional overall structure. The utility model discloses in the well prefabricated body unit aspect with the layer between continuous fibers, improved prefabricated annulus to with the layer between mechanical properties, on satisfying quick low -cost basis, improved prefabricated body mechanical properties. This prefabricated body mechanical properties is good, is difficult for the layering, and the shaping is fast, and the wholeness can be stable, is applicable to ceramic base or resin matrix composite's reinforced materials.
Description
Technical field
The utility model relates to a kind of three-dimensional preform, especially to the lifting of existing ceramic base or polymer matrix composites acupuncture three-dimensional preform performance.
Background technology
Fibre-reinforced composite is because of combination properties such as the mechanics high damage tolerance of its excellence, shock-resistant, anti-layering, antifatigues, and structural behaviour designability is strong, be widely used in tubular, tabular and polymorphic structure function integration parts, wherein according to selecting the difference of Fiber Materials, sealing-top structure parts can be applicable to aerospace field functional material, structural material etc.Bind the skeleton of precast body as such ceramic base or polymer matrix composites, the performance of the good bad influence combination process of its performance and final composite.
Chinese patent (200610013430.2) discloses a kind of capping three-dimensional fabric and method for weaving thereof, preset length in reserve warp thread method, linear latitude line stretching method and length in reserve weft yarn method three kinds of weaving process combine by this method for weaving, prepare the shaping part that binds and then adopt woven or weaving method to proceed the overall end-blocking fabric weaved in body portion.This is weaved, weaving method introduces continuous fiber, and mechanical property is good, but owing to weaving, knitting process is various, artificial participation is many, preparation cost is high, and uniformity and uniformity are difficult to control, and cannot meet the requirement of the high-performance of the precast body that binds, low cost, rapid batch production.
Chinese patent (CN102731130B) discloses designs core according to the physical dimension of antenna house, core is stung into by needle point method with quartz fabric and quartzy felt the imitated structure fabric of corresponding physical dimension, this fabric low cost, rapid shaping, but the quartz fabric described in the method need carry out cutting distinguish according to antenna house profile, cause fiber in face discontinuous, reduce rings of material mechanical property, secondly the quartz fabric interlayer described in the method is acupuncture short fiber, interlayer mechanical property is low, affects the overall performance of fabric.
Utility model content
The utility model is for above-mentioned technical problem, propose a kind of three-dimensional preform, continuous fiber layer is possessed in this precast body unit aspect, elementary layer interlayer possesses sews up continuous fiber and acupuncture short fiber, continuous fiber content is high and be evenly distributed, and hoop, is femalely distributed with continuous fiber to, interlayer, and good, the overall mechanical property of interfacial bonding strength is high, and shaping speed is fast, copying accuracy high.
For achieving the above object, the technical solution of the utility model is as follows:
A kind of three-dimensional preform, this precast body is by machine-woven fabric layer, and continuous fiber layer, net plies lamination forming unit layer, after multiple elementary layer combination acupuncture, sew is three-dimension integrally structure.
Further, in described elementary layer, machine-woven fabric layer, continuous fiber layer and net plies allocation ratio are setting value.
Further, the woven fabric of described machine-woven fabric layer is according to laying after product design profiling cutting, and its surface density is 100 ~ 640g/m
2.
Further, the net tyre surface density of described net plies is 40 ~ 160g/m
2.
Further, the continuous fiber canoe of described continuous fiber layer is spirality or grid-shaped.
Further, the needling density of described precast body is 15 ~ 35 pins/cm
2.
Further, described sewing needle is apart from being 2 ~ 20mm, and line-spacing is 2 ~ 20mm.
Further, the bulk density of described precast body is 0.30 ~ 0.88g/cm
3.
This three-dimensional preform that the utility model relates to, paste continuous fiber layer forming surface interior continuous fiber and net plies lamination forming unit layer uniformly that core laying, spirality or grid-shaped are wound around after woven fabric profiling distinguish cutting in machine-woven fabric layer, elementary layer carries out sew precast body after combination acupuncture.All possess equally distributed continuous fiber with interlayer in this precast body unit aspect, mechanical property is high, and overall performance is stablized.Be wound around by continuous fiber and compensate for woven fabric because cutting across the deficiency of the easy deformation of profiling laying, and form the complete closely knit continuous fiber layer with continuous fiber NE by design canoe in precast body inside, meet the requirement that in precast body unit aspect, all directions fiber volume fraction is high and uniformity is high.More three-dimensional woven, the braiding precast body of binding is compared, and forming process is simple, and shaping speed improves more than 50%, and preparation efficiency is high, cost is low.The precast body inside that is introduced in of isotropism net tire forms effective passage, is conducive to the uniformly penetrating of matrix in recombination process, can be introduced and connect short fiber, form network channel, be convenient to the infiltration of later stage basic material in interlayer direction by acupuncture at interlayer; Suturing skill is adopted to introduce continuous staples at precast body elementary layer interlayer, the continuous fiber of interlayer can significantly improve interlayer mechanical property and the shock resistance lesion capability of material, improve globality and uniformity that precast body strengthens structure, meet the demand for development of Aero-Space functional material, structural material high-performance, low cost.
A kind of three-dimensional preform that the utility model proposes is compared with the disclosed a kind of capping three-dimensional fabric of Chinese patent (200610013430.2), and forming process is simple, and shaping speed improves more than 50%, and preparation efficiency is high, cost is low; The continuous fiber layer in precast body unit aspect and interlayer continuous print staples is added compared with the disclosed imitated structure fabric of a kind of precast body that the utility model proposes and Chinese patent (CN102731130B), improve precast body hoop and interlayer mechanical property, on the basis meeting fast and low-cost, improve precast body mechanical property.
