Abstract
The utility model discloses a composite-fiber needled prefabricating body which is formed by continuously needling a plurality of composite-material monolayers. Each composite-material monolayer is formed in the way that panof fibers are arranged on a carbon fiber net tire to form radial fibers which are then needled continuously. By adopting the prefabricating body and based on the modernized high-technology carbon/carbon deposition industrial art, the obtained product has excellent properties of being high in carbon content, free of layering, strong in wearing resistance, resistant to high temperature, radiation and corrosion, light in weight and the like, and the producing time and the manufacturing cost of the product are greatly reduced. The composite-fiber prefabricating body with high performance is a novel functional product with a composite structure, and has broad application prospect and can be applied widely in the fields of aviation, aerospace, civil construction, sports medicine, electro-communication and the like due to the unique properties and the advanced manufacturing technology of the body.
Description
Technical field
The utility model relates to a kind of high temperature resistant, rub resistance material, specifically is a kind of composite fibre acupuncture precast body.
Background technology
High-performance composite fibre acupuncture precast body, 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 widely used novel products in field such as Aero-Space, the energy, traffic, track.
The original structure of composite pricking prefabricated body is to adopt polyacrylonitrile-based carbon fibre long fiber and net 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; Net tire and carbon fiber is compound 2., and continuous needle forms three-dimensional precast body.
Above-mentioned original composite fibre acupuncture precast body need pass through a series of reprocessings such as high temperature, carbonization again in subsequent deposition process, need the additive decrementation great amount of manpower and material resources, make production cost higher more than 30% than the overseas market, and having prolonged the production cycle, is that production cost or production efficiency all can't be competed with external product.
The utility model content
The utility model is in order to overcome above-mentioned technical deficiency, provide a kind of pre-oxygen silk fiber to combine the composite fibre acupuncture precast body made from the carbon fibre web tire, this composite pricking prefabricated body becomes the structure of three-dimensional order with the Turbostratic of fiber, has not only improved modulus, the intensity of product but also reduces cost significantly.
Composite fibre acupuncture precast body described in the utility model, this precast body is formed through continuous needle by plurality of compound material list layer, and each compound material list layer is arranged in by pre-oxygen silk fiber and forms radial fiber on the carbon fibre web tire and form through continuous needle.
Above-mentioned carbon fibre web tire thickness is 0.42-0.8mm, and compound material list layer thickness is 1.2-1.5mm, compound material list layer by layer between density be 14 ± 1 layers/cm.Needling density is 40-45 pin/cm
3
The utility model adopts pre-oxygen filament length fiber and carbon fibre web tire to prepare the high-performance composite pricking prefabricated body, and pre-oxygen silk fiber does not pass through carbonization technique, is predecessor's material of carbon fiber.The high-performance composite pricking prefabricated body that uses these the two kinds of manufacture of materials material cost more required than old technology saves about 30%, realized that subsequent product makes three-dimensional precast body through modernized carbon/carbonization with the technology of deposition three-in-one (high temperature, carbonization, deposition) and become possibility.Not only save human and material resources, and shortened the production cycle greatly.
Description of drawings
Fig. 1 is a structural representation of the present utility model.
The specific embodiment
As shown in Figure 1, composite fibre acupuncture precast body described in the utility model, this precast body is formed through continuous needle by plurality of compound material list layer, and each compound material list layer is arranged in by pre-oxygen silk fiber 1 and forms radial fiber on the carbon fibre web tire 2 and form through continuous needle.Carbon fibre web tire thickness is 0.42-0.8mm, and compound material list layer thickness is 1.2-1.5mm, compound material list layer by layer between density be 14 ± 1 layers/cm.
The preparation method of composite fibre acupuncture precast body mainly may further comprise the steps:
1) pre-oxygen silk fiber being cut into length is 38-48mm, surface density 30-38g/m
2Staple fibre, spray moisture and make staple fibre keep 3～5% humidity, put into baking oven afterwards and be heated to 30 degrees centigrade, be incubated 28-30 hour, take out staple fibre after the opener shredding forms separation of material, the staple fibre after will separating again is laid to the net tire, and the surface density of net tire is 30-38g/m
2, net tire thickness is 0.42-0.8mm.
2) pre-oxygen filament length fiber alignment is become radial fiber, be laid on the carbon fibre web tire and carry out continuous needle and form the compound material of individual layer.
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 composite pricking prefabricated body, and interlayer density is controlled at 14 ± 1 layers/cm, and stinging density in advance is 40-45 pin/cm
3, depth of needle is 16-20mm.
The utility model has not only obtained renewal on raw material, be improved especially on technical matters.For overcoming the technical deficiency of original production process, adopt the structure composition surface layer of automated machine equipment shredding and the pre-oxygen silk fiber of combing, and be dispersed in the equipment list surface layer uniformly, pre-oxygen silk fiber can not be used any chemical treatments, 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 pre-oxygen silk 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.
The utility model adopts the carbon fibre web 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/carbon depositing operation, even structure.Compound precast body 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, in subsequent deposition process, need through reprocessing technologies such as high temperature, carbonization, depositions, need a large amount of electric power resources and material resources, human input, and the carbon fiber material price is about 3 times of PAN pre-oxidized fibers silk, so just improved the cost of product, and the pre-oxygen silk fiber of the utility model/compound precast body of carbon fibre web tire has reduced cost about 30% at the finished product that the modern high technology depositing operation is made.Under the preceding topic of ensuring the quality of products, has competitiveness with external like product on the price.
