Detailed description of the invention:
A kind of novel connector making composite of the present invention, including aluminum particulate, carbon nano-particles, low-viscosity polyamides, glass fibre, epoxy resin, by weight percentage, the mass content of the most each material is aluminum particulate 4-8%, carbon nano-particles 6-12%, low-viscosity polyamides 24-35%, glass fibre 13-25%, epoxy resin 33-52%.
In the composite of the present invention, it is calculated in mass percent, aluminum particulate 4-8%, carbon nano-particles 6-12%, preferably, wherein aluminum particulate 5-6%, carbon nano-particles 8-10%, having the micro structure comprising the microcrystalline at least partly separated by carbon nano-particles, the size of microcrystalline is that 10 nanometers are to 100 nanometers.Owing to making nano microcrystalline nanometer stabilisation by carbon nano-particles, can be in the temperature holding position dislocation density of the fusing point of some phases close to this aluminum particulate and the hardness of relative raising.This means can keep the certain mechanical strength of this connector and hardness by manufacturing this connector in the hot-working of the temperature of the fusing point of some phases close to this carbon nano-particles or extrusion molding simultaneously.Due to above-mentioned nanometer stabilisation, under hot-working, even also keep Young's modulus and the hardness improved, simultaneously because carbon nano-particles is along little, the preferably crystal boundary location of nano level metal crystallite, dislocation motion can be suppressed and the dislocation in carbon nano-particles stable metal can be passed through, due to the very high surface/volume ratio of nano-sized crystal, this stabilisation is highly effective.If additionally, use the alloy that strengthened by solution hardening as metal ingredient, can by with the engaging or interlock and stablize the phase of mixed crystal or solid solution of carbon nano-particles.In the microcrystalline used by this connector, nanoparticle not only part is spaced from each other by carbon nano-particles, and some carbon nano-particles also comprise or are embedded in crystallite.This can be considered as carbon nano-particles prominent from crystallite as " hair ".These carbon nano-particles embedded play a significant role in terms of preventing dislocation density reduction.Use existing Mechanic Alloying Technology, the crystallite less than 100 nanometers of the size containing the carbon nano-particles embedded can be manufactured.In some cases, according to the diameter of carbon nano-particles, embedding carbon nano-particles in the crystallite of size 100 nanometer to 200 nanometers may be easier to.Especially, by the additional stabilization effect of the carbon nano-particles embedded, it has been found that nanometer stabilisation is the most highly effective to the crystallite of 200 nanometers to size 100 nanometer.
