they would likely run in to similar problems. metal matrix composites in general are hard to make and underperform. i just know the most about al/c composites.
also, aluminum and titanium are already really strong and light. the author wanted to include carbon fiber because "it's perfectly rigid and doesn't bend" and that "scratches are a thing of the past". i appreciate that he wants a bit of far-out flourish for his new design, but both of those statements are way off the mark technically, and would be poor and wrong reasons to pursue difficult to make metal-matrix composites.
