Description
Technical field
The present invention relates to a kind of automobile energy absorbing member, especially relate to a kind of carbon fiber, aramid fiber mixes type
Strengthen three dimensional structure energy absorbing member.
Background technology
According to official statistics, since the later stage eighties 20th century, Road Traffic Accidents in China quantity, death toll, ten thousand cars
Accident death rates etc. are all in world's umber one.China's automobile guarantee-quantity in 2009 accounts for the 3% of the world, and the death of vehicle accident
Number but accounts for 16%, and the safety improving the vehicles is extremely the most urgent.
At present there is a two types for the parts of protection occupant during collision in vehicle: the high rigid frame high energy that eases up is inhaled
Receive parts.High rigid material, such as bumper bar and body shell, mainly provides enough physics when vehicle collides for occupant
Safe space, thus require that rigidity is strong, deforms little, but impact energy absorbability to external world is low, it is impossible to reduce external impact
The power injury to occupant；On the other hand, for the high-energy absorption material of buffering, such as between the bumper bar and front longitudinal of vehicle
Place one group of cast energy-absorbing element, can effectively be absorbed the energy of shock by the deformation of parts and the destruction of self, no
Only reduce the impact to high rigidity car body, and slow down the too fast increase of deceleration, reduce the collision physiological damage to occupant.
As shown in Figure 1-2, generally rear side in vehicle front bumper 1 installs the energy-absorption box 2 of one group of metal material as energy
Amount absorption piece, energy-absorption box 2 is fixed on front longitudinal by rivet, makes vehicle effectively absorb shock in collision process
Energy, the life safety of the passenger that adequately protects.But generally self is heavier, mainly by the plasticity of metal material for ordinary metallic material
Deformation carrys out energy-absorbing, and the most now by metallic material of aluminum, its specific energy absorption value (energy value that unit mass absorbs) is only 44.6kJ/
Kg, energy absorption is on the low side, can not meet the development trend of automotive light weight technology, low energy consumption and high security.
Carbon fiber has the characteristic of high-modulus, high intensity, and aramid fiber extension at break is up to 2.5-3% simultaneously, by rationally setting
The structure of meter composite reduces the stretching, extension of Median cracks, can reach high bending, the purpose of multi-fiber fracture destruction, maximum limit
The absorption failure energy of degree, delays impact velocity, reduces the harm to vehicle-mounted passenger.
Composite refers to, by two kinds or the two or more material with different physics, chemical property, with microcosmic, be situated between and see
Or the different layer of structure such as macroscopic view, the material system formed through complicated spatial organization.By different size,
In different levels, structure Design and optimization can obtain in performance and functionally new considerably beyond its simple substance component property and function
Material, current composite is all widely used in fields such as Aeronautics and Astronautics, weapons, naval vessels.But as energy absorbing parts of automobiles
Application has no Patents or report.
Summary of the invention
To be solved by this invention is that existing Vehicular metal energy-absorbing element energy absorption is undesirable, quality heavy, no
The problems such as the requirement meeting safety, light weight, energy-conserving and environment-protective.
In order to solve above-mentioned technical problem, the invention provides a kind of automobile-used hybrid composite energy absorbing part,
It is characterized in that, described energy absorbing member is round tubular parts, including the first aramid fiber layer from the inside to the outside, carbon fiber
Layer, the second aramid fiber layer.
Preferably, described first aramid fiber layer, the second aramid fiber layer are with aramid fiber as reinforcement, asphalt mixtures modified by epoxy resin
Fat, phenolic resin or unsaturated polyester resin are substrate；Described carbon fiber layer is with carbon fiber as reinforcement, epoxy resin,
Phenolic resin or unsaturated polyester resin are substrate, and the first aramid fiber layer, carbon fiber layer, the second aramid fiber layer use
Substrate identical.
Preferably, described first aramid fiber layer, carbon fiber layer, the second aramid fiber layer thickness than for 1:10:2.5；
The pipe thickness of described energy absorbing member and diameter of inner pipe are than for 1:22.
The automobile-used hybrid composite energy absorbing part that the present invention provides can also be used with basalt fiber, carbon fiber
Layer, glass layer substitute described first aramid fiber layer, the second aramid fiber layer, or/and by basalt fiber, glass fibers
Dimension layer substitutes carbon fiber layer；Substitute the first aramid fiber layer, the second aramid fiber layer material identical, and with substitute carbon fiber layer
Material different.
Present invention also offers the production method of above-mentioned automobile-used hybrid composite energy absorbing part, its feature exists
In, comprise the following steps:
Step 1): by aramid fiber, carbon fiber infiltration substrate standby；
Step 2): winding step 1 on core successively) prepare aramid fiber, carbon fiber, aramid fiber, formed respectively
First aramid fiber layer, carbon fiber layer, the second aramid fiber layer, make hybrid composite energy absorbing part；
Step 3): by step 2) prepare hybrid composite energy absorbing part solidification after slough core.
Preferably, described step 1) method that is wound around is: it is axially 0 ° with the pipe axle of mandrel, the winding angle of aramid fiber
Being 75 °～90 °, the winding angle of carbon fiber is 5 °～20 °.
Further, described step 1) method that is wound around is: it is axially 0 ° with the pipe axle of mandrel, the winding angle of aramid fiber
Degree is 88 °, and the winding angle of carbon fiber is 17.6 °.
Preferably, described step 1) in the first aramid fiber layer, carbon fiber layer, the thickness ratio of the second aramid fiber layer be
1:10:2.5；The pipe thickness of described energy absorbing member and diameter of inner pipe are than for 1:22.
Preferably, described step 3) in solidification method particularly includes: temperature be 20 ± 2 DEG C, relative humidity be 65 ± 5%
Under conditions of solidify 24 hours.
The present invention uses complementary reinforcing fiber to be reinforcement, and carbon fiber has the characteristic of high intensity, high-modulus, when carbon is fine
Dimension occurs to realize high energy-absorbing during fracture, although aramid fiber compression performance is significantly worse than tensile property, but extension at break
Up to 2.5-3%, utilizes three interlayers every complementary winding arrangement so that aramid fiber compresses on 0 ° of direction in compression process,
While being converted into stretching on 90 ° of directions, limit deformation and the extension of composite inner Median cracks of carbon fiber, the most greatly
Degree improves the quantity of fibrous fracture, thus absorbs more substantial energy.Winding shaping process, the most Wrapping formed by fiber,
The manufacture process damage to fiber need not be reduced largely through operations such as such as longitude and latitude intertexture, braidings, improves making of fiber
Use performance.
The composite energy absorption mechanism of present invention offer is with the absorption mechanism of conventional metals energy absorbing member not
With, traditional metal material carrys out energy-absorbing mainly by its plastic deformation, and its load the most significantly declines, its
Amount of energy is on the low side；The present invention is tubular composite material, its mainly by fibrous fracture, bend, deform, the mode such as layering is inhaled
Can, its load declines and keeps stable load the most by a small margin.This characteristic can reduce further
Foreign impacts is to car body after energy absorbing component and the injury of occupant in car body, and the high frequency repeated stock i.e. with certain amplitude reduces
Injury to occupant.
