The performance of graphite products depends on the composition. Graphite has a co-layer structure, and each layer has different capabilities such as high strength, high stiffness, high conductivity, high insulation, and low-temperature physical properties. In terms of mechanical properties, high strength is helpful in automotive (printing) assembly, but high stiffness is not actually required for components.

Material mechanics and material physics analyze the different components and directions of different materials to simulate the performance of metal materials at the macro scale.

There are too many, I can't tell at the moment. This is a very huge mathematical proposition. I can't remember how many people have asked me. There is a 90% probability that I can't answer it.

Theoretically it is necessary, but mechanics of materials needs to involve composition. Perhaps in the design, only the strongest material with the performance corresponding to the substance is required. However, the comprehensive performance of graphene and the total capacity of graphite eutectic need to be considered in a higher dimension. For example, randomly introduce some energy density, material passability, permanent magnetic properties, etc.

The ultra-high strength of graphene and the ultra-small gaps between graphenes are of great help to the processability of crystals and the heat-fusibility of graphene itself.

Yes, but graphene is extremely unstable as a nanomaterial, and its mechanical properties are poor.

There is no absolute right or wrong, only relative strength and relative stiffness. Otherwise, why is graphene more flexible than carbon steel?

There is no absolute right or wrong, but it is relatively reasonable, and it depends on the specific situation

There should be reasonable, but probably not fully quantifiable characterization

Yes, but take into account that there is no absolute right or wrong in theory, it depends on the mechanical structure of the material, processing, cost, etc.

sure. For example, if you make it into plastic or something, it must have performance problems. However, graphene, graphene oxide, or carbon graphene is difficult to use specific parameters to qualitatively and quantitatively analyze it. In practical problems, graphene + magnetism (the same as graphene is also affected by the same physical properties), now it is clearer, it is roughly similar to the resin structure, and it can indeed be applied to graphene as a rubber gasket (two Both are reliable rubber). But it will face the mutual constraints of function and price.

If you are interested, you can also look for it, the test and design of three-dimensional graphene. In layman's terms, graphene is a material that can only use a diffractive layer. To achieve the best theoretical effect, at least 1. Strengthen the reflective surface.  2. Strengthen the conductive layer.  3. Heat dissipation layer.  4. Conductive oxide layer.  5. Not much to say about electric conduction and heat conduction, it is probably these few steps.
