Description
Technical field
The present invention relates to a kind of composite spring, more particularly, to a kind of carbon fibre composite helical spring and its system
Make method and mould.
Background technology
In recent years, world energy sources crisis and petroleum price rise and environmental problem, an urgent demand automobile is towards light-weighted direction
Development, be usually used light material (or new material) substitute traditional material structure lightened as target to realize, further improve
Fuel utilization ratio has become one of focus of research.
Light material (or new material) includes high strength steel, aluminum, magnesium and titanium alloy, plastics and composite etc.；With gold
Category material compare, carbon fibre composite (such as carbon fibre reinforced plastic (hereinafter, referred to CFRP)) be lightweight, high rigidity,
The advantages of high intensity, high antifatigue, wear-resisting and good antivibration absorbing, its specific modulus are higher than 5 times of steel and aluminium alloy, than strong
3 times higher than steel and aluminium alloy, but proportion very little is spent, the weight of per unit volume only has the 20% of steel.Additionally, carbon fiber is multiple
Condensation material has higher corrosion resistance and a relatively low thermal expansivity, more more robust than steel and be difficult to get rusty, and car manufactures are
Energetically carry out attempting for lightweight composite being applied to interior material for vehicle, vehicle body, leaf spring, vehicle bumper etc..
However, conventional springs (i.e. helical spring) great majority are wound and made, manufacturing process by metal materials (steel)
Extremely complex；And physical property of the spring mainly by metal material, realize that by certain conversion regime which stores energy
Amount and release energy, so as to make the spring with damping, pooling feature, and be applied to various mechanisms and industrial machinery
On part, such as on automobile, locomotive and aerospace field (CN103573892 A).For adapting to the demand of industry development, metal
The spring that material is made is difficult to meet use demand, and has reached one from design, selection, manufacture and inspection metal spring
Individual bottleneck period.Therefore, preparing coil type spring alternative metals helical spring with carbon fibre composite will become industry development
Trend.
Many researcheres have been attempted manufacturing coil type spring using CFRP.However, because the easily pressurized stresss under compression of CFRP or
The impact of shear stress, produces coil type spring by single carbon fibre tow and is difficult to produce enough tension force and carry to elastomer
For bounce (103388642 A of CN).Separately have, the spring that carbon fibre composite makes is faced with some challenges, such as elasticity
Poor, frangible, anisotropy is high, and these characteristics are substantially to be not suitable for spring, from and the carbon fibre composite spring produced
Deformation is little, and coefficient of elasticity is low, and bearing load is little.Therefore, using the high-tensile that carbon fibre composite is unique, design is a kind of
The composite spring of special construction can be only achieved big bearing capacity (2014/014481 A1 of WO；WO 02/099307 A1；US
2852424 A；US 4773633 A；US 8857801 B2；US 7857294 B2；US 5685525 A；US 4260143 A；
CN 104690984 A；CN 103221199 A).Therefore, in the urgent need to develop one kind can realize mitigate weight, have excellent
Durability and replace the carbon fibre composite helical spring structure of ordinary metallic material helical spring most important.
The making fibre reinforced composites coil type spring that currently mentions manufacture method is good, operation difficulty big, consumption
When taking a lot of work, it is desirable to which equipment capital input is big, waste of material is serious, and the carbon fibre composite component costs of production are high.(EP
0637700B1；US 8490530B2；CN 1480658A；CN 1651795A；CN 1232931A；CN 101439580A)
Additionally, existing manufacture fibre reinforced composites spring forming mould (2647481 A1 of EP；US 4434121
A；US 5988612 A；US 4473217 A；US 6986203 B2；102909870 A of CN), design process is complicated, molds into
This height, the die-filling and demoulding are difficult, low production efficiency.And during mould closure heating, as carbon fiber is infiltrated by resin
Uneven and cause product surface or inside to there is bubble, cause surface irregularity.In process of production due to resin reaction
Internal stress is produced, when helping without external force, internal stress cannot be offset, strong influence, meeting can be produced to the strength character of product
Directly affect the service life of product.
