Abstract
The utility model discloses a PANOF (Polyacrylonitrile Oxidized Fiber) acupuncture preform which is formed by the way that a plurality of layers of composite materials are continuously acupunctured. The utility model is characterized in that each single layer of composite material is formed by two layers of PANOFs and a layer of PANOF web at the middle, and the layers of PANOFs are formed by the way that the PANOFs are radially and uniformly arranged on the upper and lower surfaces of the PANOF web, and are continuously acupunctured. A product produced by the utility model is the product produced by the modernized high-technology carbon/carbon deposition process, which has high carbon content, is not layered, and has strong wear resistance, high temperature resistance, radiating resistance, corrosion resistance, light mass and other good properties, and the production time and the manufacture cost can be greatly reduced. The PANOF acupuncture preform is a novel product with a functional structure, and by the special properties and advanced process, the fiber product has wide application and prospect in aviation, aerospace, civil construction, sports medicine, electronic communication and other fields.
Description
Technical field
The utility model relates to a kind of high temperature resistant, rub resistance material, specifically is a kind of pre-oxygen silk acupuncture precast body.
Background technology
Pre-oxygen silk acupuncture precast body, being by the PAN(polyacrylonitrile fibre) pre-oxygen silk fiber and pre-oxygen silk screen tire be after modern chemical high temperature, high pressure, every carbon/carbon depositing operation are handled, have characteristics such as high temperature resistant, rub resistance, quality be light, being the high section green wood that modernization development is generally acknowledged, is the novel product of the important structure part of field extensive uses such as Aero-Space, the energy, traffic, track.
Original technology of pre-oxygen silk acupuncture precast body is to adopt polyacrylonitrile-based carbon fibre long fiber and web of staple fibers tire to make three-dimensional precast body through multilayer acupuncture.Processing step mainly comprises: 1. staple card Cheng Houwei 1-2mm, the surface density that will grow for 50-60mm are 40-600g/m
2The net tire; 2. compound and acupuncture successively constitutes three-dimensional precast body with pre-oxygen silk fiber with the net tire.
The structural strength of the said goods is lower, and elastic modelling quantity is not high, causes the credit rating of product not high, and along with aerospace field constantly promotes this product demand, the existing product performance seems and can't adapt to.。
The utility model content
The utility model provides a kind of pre-oxygen silk acupuncture precast body in order to overcome above-mentioned technical deficiency, and this acupuncture precast body becomes the Turbostratic of pre-oxygen silk fiber the structure of three-dimensional order.Not only improve modulus, the intensity of product, and reduced cost significantly.
A kind of pre-oxygen silk acupuncture precast body described in the utility model, this precast body is formed through continuous needle by plurality of compound material list layer, it is characterized in that: each compound material list layer is by two-layer pre-oxygen silk fiber layer and the middle pre-oxygen silk screen of one deck tire are made up and down, pre-oxygen silk fiber layer is formed by pre-oxygen silk fiber and radially is evenly arranged in pre-oxidation silk screen tire upper and lower surface, forms through continuous needle.
Above-mentioned pre-oxygen silk acupuncture precast body, pre-oxygen silk screen tire thickness is 0.42-0.8mm, and compound material list layer is 1.8-2.2 mm, and interlayer density is 12 ± 1 layers/cm, and needling density is 35-40 pin/cm
3
The utility model has not only upgraded raw material, and has improved production technology.For overcoming the technical deficiency of original production process, adopt the structure composition surface layer of full-automatic machinery shredding and carded fiber, and (fiber can not be used any chemical treatments to be dispersed in the equipment list surface layer, otherwise influence the subsequent quality index of goods,) adopt multi-angle successively to intersect acupuncture, the dynamic seal of realizing fibre structure is right, make the Turbostratic of fiber become the structure of three-dimensional order, the fiber web tire of making has the random level section structures in the planes of 360 degree, has increased substantially the modulus and the intensity of product behind the follow-up carbonization technique.
Description of drawings
Fig. 1 is a structural representation of the present utility model.
Fig. 2 is the structural representation of compound material list layer among Fig. 1.
The specific embodiment
As shown in Figure 1, pre-oxygen silk acupuncture precast body described in the utility model, this precast body is formed through continuous needle by plurality of compound material list layer.As Fig. 2, each compound material list layer is made by two-layer pre-oxygen silk fiber layer 2 and the middle pre-oxygen silk screen of one deck tire 1, and pre-oxygen silk fiber layer 2 is formed by pre-oxygen silk fiber 3 and radially is evenly arranged in pre-oxidation silk screen tire 1 upper and lower surface, forms through continuous needle.Pre-oxygen silk screen tire thickness is 0.42-0.8mm, and compound material list layer is 1.8-2.2 mm, and interlayer density is 12 ± 1 layers/cm.
The preparation method of this pre-oxygen silk acupuncture precast body may further comprise the steps:
1) pre-oxygen silk fiber being cut into length is 50-100mm, surface density 60-200g/m
2Staple fibre, spraying moisture on staple fibre makes it keep 3～5% humidity, put it into and be heated to 30 degree in the baking oven, be incubated after 28-30 hour, take out staple fibre after the opener shredding forms separation of material, staple fibre after will separating again is laid to the net tire, and the superficial density that makes the net tire is 54-206g/m
2, net tire thickness is 0.3-0.6mm;
2) the upper and lower surface of the 2 layers of pre-oxygen silk fibers difference of PAN arranged radially one-tenth at the net tire, and carry out the compound material of continuous needle formation individual layer, fiber content wherein is 80-90%, and thickness is 0.6-0.9mm, surface density 256g-348g/cm
2, bulk density is 0.5-0.65g/cm
3, net tire content 30%-13%, needling density is 35-40 pin/m
3
3) with step 2) the compound material of individual layer of preparation is the elementary cell of product, successively intersects continuous needle through multi-angle and forms pre-oxygen silk acupuncture precast body, and interlayer density is controlled at 12 ± 1 layers/cm, and stinging density in advance is 40-45 pin/cm
3, depth of needle is 16-20mm.
The utility model adopts pre-oxygen silk screen tire to be of value to the intensity that improves the precast body interlayer structure.Make the precast body levels integrated by intersection acupuncture, guarantee carburizing rate height in carbon/carbonization, the depositing operation, even structure.The pre-oxygen silk fiber of PAN/pre-compound precast body of oxygen silk screen tire with make precast body with carbon fiber entirely and compare, because of full precast body with carbon fiber is a front char-forming material in the deposition process, needing in subsequent deposition process needs the input of a large amount of electric power, material resources, manpower through reprocessing technologies such as high temperature, carbonization, depositions.The carbon fiber material price is about 3 times of the pre-oxygen silk fiber of PAN.Improved the cost of product like this.And the utility model adopts pre-oxygen silk acupuncture precast body, and the finished product of making at the modern high technology depositing operation has reduced by 30% left and right sides cost.Under the prerequisite of ensuring the quality of products, price of this product and external like product have competitiveness.
