Abstract

The invention relates to a carbon fiber bar skeleton of a composite material in a four-dimensional carbon fiber bar. The carbon fiber bar skeleton is characterized in that: four groups of the carbon fiber bar skeletons are arranged and comprises a left group, a right group, a front group and a back group, each group of the carbon fiber skeletons is composed of a plurality of rows, the rows are parallel with each other, each row is composed of a plurality of round carbon fiber bars, the round carbon fiber bars are parallel with each other, all the carbon fiber bars between adjacent groups are mutually perpendicular to each other on a vertical projection surface, each group of the carbon fiber bars form same included angle with a horizontal plane, the four groups of the carbon fiber bars skeletons lie on a same horizontal plane, row spacing of the four groups of the carbon fiber bars skeletons are all equal to that of the carbon fiber bars in each row, four carbon fiber bars of the four groups of the carbon fiber bars skeletons on a same row is tangent at a point, and the tangent points among the four carbon fiber bars in the same row lie on a same horizontal plane. The advantages reside in that: a unit of the carbon fiber bar is in a rectangular pyramid shape, a structural body is difficult to be distorted and deformed; incised from whatever the direction is, the carbon fiber bars form a net shape, accordingly the carbon fiber bars bear uniform force and multidirectionally resist impact force. Open channels is existed between all the carbon fiber bar skeletons, so has big a space duty ratio, are extended to a CVD process, and make the treatment of the filling very smooth.

A kind of carbon fiber rod skeleton of four-dimensional carbon fiber rod structural composite material

Technical field

The present invention relates to a kind of carbon fiber rod structural composite material, especially relate to a kind of carbon fiber rod skeleton of four-dimensional carbon fiber rod structural composite material.

Background technology

At present, three-dimensional carbon fiber rod composite material is because of premium properties such as it is high temperature resistant, corrosion-resistant, anti-impact forces, and people are applied in them in each field such as Aero-Space, high-end industry widely.But in actual application, three-dimensional carbon fiber rod composite material causes existing following defective because the carbon fiber that adopts is three-dimensional horizontal vertical and vertical structure:

One: because it is stressed not to be that multi-angle strengthens, therefore stressed insufficient strength evenly (be subjected on the parting face force intensity inconsistent) can not multi-faceted opposing impulsive force;

Its two: because itself is by the chopped carbon fiber bar construction, therefore limited the solid characteristic of carbon fiber rod itself, the advantages such as it is high temperature resistant, corrosion-resistant, anti-impact force can not get demonstrating fully;

Its three: because of the three-dimensional carbon fiber rod skeleton dutycycle of three-dimensional carbon fiber rod composite material inside larger, space between it is less, put into mould when three-dimensional carbon fiber rod skeleton and strengthen polymethyl methacrylate, epoxy resin, poly-aryl ethane silicones, during the casting of reinforced polyether ether ketone, can produce resistance, cause the enhancing polymethyl methacrylate of casting, epoxy resin, poly-aryl ethane silicones, reinforced polyether ether ketone etc. produce bubble, thereby made composite has flaw, when composite term high-tech and high-end aerospace field, when running into HTHP, slight flaw will bring the collapse of total, thereby bring the loss that to bear, therefore demand developing the novel four-dimensional carbon fiber rod structural composite material that can overcome the new carbon fiber rod skeleton structure of having of above-mentioned shortcoming urgently.

Summary of the invention

The objective of the invention is to solve the existing the problems referred to above of three-dimensional carbon fiber rod composite material of the prior art, a kind of four-dimensional carbon fiber rod structural composite material of firm, the stressed even intensity of a kind of Stability Analysis of Structures, the multi-faceted opposing impulsive force of energy is provided.

The present invention designs a kind of carbon fiber rod skeleton of four-dimensional carbon fiber rod structural composite material, it is characterized in that: the carbon fiber rod skeleton has four groups, the carbon fiber rod skeleton divides four groups of left-right and front-backs, every group of carbon fiber rod skeleton is comprised of some rows, be parallel to each other between row and row, every row is made of some carbon fiber rods, be parallel to each other between root and the root, all carbon fiber rods between the adjacent set are mutually vertical on vertical plane, every group of carbon fiber rod skeleton is horizontal by same angle, four groups of carbon fiber rod skeletons are positioned on the same level, row's spacing of four groups of carbon fiber rod skeletons and every row's root spacing all equate, mutually tangent on one point between four carbon fiber rods of the same row of four groups of carbon fiber rod skeletons, the points of tangency between four carbon fiber rods of same row is positioned at same level.It is characterized in that: carbon fiber rod is circular rod.

The present invention has obtained following effect owing to adopting technique scheme:

One: for the uniform problem of the stressed insufficient strength of three-dimensional carbon fiber rod composite material, owing to having adopted four-dimensional structure, the elementary cell of its formation is rectangular pyramid, structure is difficult for distortion, distortion, which no matter from direction cut, all consist of nettedly, so holding capacity is average, can multi-faceted opposing impulsive force.

Its two: for the problem of three-dimensional carbon fiber rod composite material majority by the chopped carbon fiber bar construction, because the rectangular bundle of carbon fiber rod has been integrated into carbon fiber rod rod, so draftability is good, can keep the characteristics such as carbon fiber rod itself is high temperature resistant, corrosion-resistant.

Its three: the problem of follow-up CVD operation being brought resistance for three-dimensional carbon fiber rod composite material: the present invention because all carbon fiber rod skeletons between have open channel, so the space dutycycle is larger, account for 18%---20%, be extended in the CVD operation, can make PROCESS FOR TREATMENT very well.

Description of drawings

Below in conjunction with accompanying drawing and specific embodiments of the invention the present invention is described in further detail.
