    • How about a set of composite (carbon forged) pistons to pair with your carbon connecting rods?

      The idea of composite engine internals is intriguing for several reasons. Those reasons that apply to the connecting rods such as the composite material not fatiguing like metal over time or losing shape also apply to pistons.


      Obviously heat will also not have the same effect on the carbon composite material as on metal.

      Who is using these in an actual application though?

The above photos represent an early iteration of our design, which has led us to the development of the worlds first production full carbon composite piston. We anticipate release in Q2 2020.
      AWA Composites claims less weight and higher air-fuel ratios. Essentially, higher performance.

      Where is the proof? These pistons are expected to hit the market later this year and we certainly will be watching closely.

        This would be cool. Wonder if they need ceramic coating on the tops and maybe around the rings/skirts?

        It does seem less likely to scuff piston walls and probably expand/contract less than forged aluminum pistons so hopefully less oil burning and wallowing out the cylinder bores.

        +1 and hopefully this means built motors last longer.

        Less carbon deposits on cooler running pistons also.
