How much additional effort is that on top of the current process of making gorilla glass, though? I believe it already requires some mighty temperatures+pressures.
High temperatures are true of glass work in general. I'm not 100% about the gorilla glass process, but I did not think it high pressure one.
And high pressure is not a deal breaker -- it's just the best way to make some things right now. But even after you've forced carbon and aluminum together, you have a variety of other issues then to deal with: large potential for galvanic corrosion and huge difference in coefficient of thermal expansion are two of the primary ones. The fact that they have horrible wetting behavior is another one, and is the reason they have to do squeeze casting in the first place, but likely also negatively affects the quality of the interface formed between the carbon and the aluminum (thus leading to poor properties even after you've spent all the effort of making it)
