graphite manufacturers gpa above graphene7/7/2015
of the product is successfully developed more than 700 mpa level of graphene aluminum matrix composites, and the elastic modulus of 95 gpa above graphene aluminum matrix composite material.Material is set "graphene reinforced metal matrix nanocomposites", not only invented a kind of excellent performance of new graphite suppliers high-end metal matrix nanocomposites, the material or will also aviation spacecraft bring revolutionary change for the future.For the first time by means of optical microscope (OM), scanning electron microscope (SEM) and transmission electron microscopy (TEM), and other modern materials characterization of graphene reinforced metal matrix microstructure of the nanocomposites were characterized, and its tensile properties test.Results show that the graphene nano piece of uniform distribution in aluminum alloy matrix, the interface integration with the substrate to form a good atomic scale, and graphene nano did not react with aluminum alloy matrix, and retain the original nano structure.Mass fraction is added to the aluminum alloy, for example, only 0.3% of graphene nano films, the yield strength and tensile strength of 322 mpa and 455 mpa, respectively is not add graphene nano piece was increased by 58% and 25% respectively, and the aluminum alloy and aluminum alloy elongation does not decrease. In the above areas, the supply chain there are breakthroughs.Foundation, for graphite manufacturers example, based on aluminum and titanium material court graphite material suppliers ink materials research foundation, using the characteristics of graphene high thermal conductivity, and the high quality of material produced graphene powder and specific surface area and the characteristics of easy to disperse, thermal conductivity, give full play to the graphene in guarantee the process performance and the requirements of the linear expansion at the same time, successfully developed the thermal conductivity is greater than 210 W/moK graphene electronic encapsulation materials, technical index doubled compared, bending strength increase 3 times, elastic modulus incr
