• It’s easier to cut (main reason) and it’s better in compression and shear than Nomex. You’d usually use Nomex on thinner gaps. I shaved a thicker bit down to the correct thickness. Bonding it in is no different as I’ve used what I believe is the strongest 2-part epoxy adhesive available. We’ve got stronger adhesive films which are lighter, but I’d have to tape it all up and vac bag it, whereas with this I can just spread it on and weight it down on the surface table overnight. I forgot to take a pic before I put it together!

  • Ah right, makes sense. Not having to bag it would have been enough of a reason for me.

    M40J is a mostly outdated fibre

    This made me laugh, by the way. A year ago this was our high-end fibre, only used on special occasions. But then again, you lot probably spend more on a single wing element than a student team on their entire car.

  • We’ve got a couple of generations of fibre newer than M40J. M46J pretty much superseded it, which is a general purpose stiff fibre, but there’s a whole new generation of fibres coming through that offer higher strength as well as the high stiffness. These are replacing those older-style fibres where you had a choice of high strength, high modulus, or somewhere in between but not both.
