Another big change is the use of CFRP for the wings instead of aluminum alloys such as Al7055. While Al7055 has a density of 2.86 kg per cubic decimeter, CFRP has a density of 1.7 - 1.95 kg per ...

However, this high energy-to-mass ratio is starkly contrasted by its volumetric energy density, a mere 8 megajoules per liter ... enveloped in carbon fiber-reinforced polymer (CFRP) using epoxy resin.

Recycled nonwoven CFRP typically uses a lower fiber volume fraction (25-35%) when consolidated compared to a woven variant (60%+), resulting in a higher resin content and lower overall density.
