Abstract
The invention discloses a carbon fiber flywheel and belongs to the technical field of composites. The carbon fiber flywheel is formed by superposing a plurality of layers of preimpregnated round carbon fiber stocks according to different angles prior to compression molding and machining. The carbon fiber flywheel has the advantages that hoop tension strength of a flywheel structure is enhanced to enable the flywheel not to be damaged during high-speed rotation, so that rotating speed of the flywheel is increased; the problem that a metal flywheel low in strength is incapable of rotating at a high speed to store energy is solved.
Description
Technical field
The present invention relates to a kind of flywheel, particularly relate to a kind of carbon fibre flywheel.
Background technology
What flywheel was mounted on machine gyroaxis has the colyliform accumulator of relatively large rotating inertia.When machine rotational speed increases
Time, the kinetic energy of flywheel increases, and energy storage or saving is got up；When machine rotational speed reduces, flywheel energy reduces, and energy is discharged
Come.Flywheel can be used to reduce the velocity perturbation of machine operation process.
Flywheel is used for machinery energy storage, and its energy storage density is the main indexes of its performance.Improve flywheel energy storage close
Degree has two approach: one is to increase flywheel rim quality, and two is to improve Speed of Reaction Wheels；The former causes mechanism cumbersome, the latter's effect
Significantly, but limited by three aspects: one is to ensure that flywheel rim material will not break because intensity is not enough when centrifugal force increases
Splitting, it limits the increase of rotating speed；Two be flywheel ultrahigh speed rotate time, bearing can generate heat, heats up, lose efficacy, and lubricating oil can go bad, it
Also limit rotating speed to increase；Three be Speed of Reaction Wheels the highest time, the energy consumption of air drag and bearing frictional torque all can dramatically increase, make
Flywheel energy storage efficiency reduces.Due to the restriction of above-mentioned three aspects, known metal material flywheel, owing to metal strength is low, it is impossible to
Meet the use needs of high speed flywheel.
Summary of the invention
For solving above technical problem, the present invention provides a kind of carbon fibre flywheel, to realize its high-speed rotation.
For reaching above-mentioned purpose, one carbon fibre flywheel of the present invention, described carbon fibre flywheel is justified by multilamellar carbon fiber prepreg
By different angles superposition, by after compression molding through being machined into.
The circle that wherein said carbon fiber prepreg circle is cut into by certain size for unidirectional carbon prepreg.
Wherein said different angles are formed by adjacent levels carbon fiber prepreg circle lines.
The carbon fiber prepreg circle of wherein said carbon fibre flywheel is 600 layers.
The invention difference from existing technology is that the present invention achieves following technique effect:
The carbon fibre flywheel that the present invention provides, improves the hoop tensile strength of flywheel structure so that it is do not send out when high speed rotating
Raw destruction, thus improve Speed of Reaction Wheels, solve metal flywheel strength low, it is impossible to the problem that high speed rotating carries out energy storage simultaneously.
The invention will be further described below in conjunction with the accompanying drawings.
Accompanying drawing explanation
Fig. 1 is the structural representation of carbon fibre flywheel of the present invention；
Fig. 2 is carbon fiber prepreg of the present invention circle package assembly schematic diagram.
Description of reference numerals: 1-5-carbon fiber prepreg circle.
Detailed description of the invention
Below in conjunction with embodiment, to the present invention, above-mentioned and other technical characteristic and advantage are described in more detail.
As it is shown in figure 1, carbon fibre flywheel of the present invention is pressed different angles multiple-layer stacked by carbon fiber prepreg circle 1-5, pass through
Compression molding, by being machined into.
The present embodiment flywheel is in forming process, during according to construction features for being primarily subjected to high-speed rotation in running
Centrifugal force, structurally take the carbon fiber prepreg multiple-layer stacked of different angles.
Specifically, carbon fibre flywheel external diameter is 440mm, and thickness is 112mm, and using thickness is the unidirectional carbon fiber of 0.2mm
Dimension prepreg circle 600 layers.The present embodiment flywheel is in forming process, according to construction features for be primarily subjected in running
Centrifugal force during high-speed rotation, structurally takes the carbon fiber prepreg multiple-layer stacked of different angles.
In sum, the present invention is by selecting the carbon fibre flywheel of carbon fiber prepreg circle superposition compression molding, it is achieved that
Carbon fibre flywheel global formation, improves the hoop tensile strength of flywheel structure so that it is do not destroy when high speed rotating, from
And improve Speed of Reaction Wheels；Solve metal flywheel strength low, it is impossible to high speed rotating carries out the problem of energy storage, carry out high energy for follow-up
Storage flywheel development is laid a good foundation.
Embodiment described above is only to be described the preferred embodiment of the present invention, the not model to the present invention
Enclose and be defined, on the premise of designing spirit without departing from the present invention, the those of ordinary skill in the art technical side to the present invention
Various deformation that case is made and improvement, all should fall in the protection domain that claims of the present invention determines.
