Topic: Building methods Posted: 08 Oct 19 at 11:38am |
I built a Cherub to Clive Everest's design and it was built from a mix of water jet cut prepreg carbon panels and waterjet cut foam panels. There is a thread with loads of pictures on the Cherub forum. http://www.uk-cherub.org/forum/index.php/topic,2325.0.html The hull plug was made with lots of small chines all CNC cut out and fitted onto matched frames. For the hull a foam sheet was cut into shapes that fit all the flat chines on the plug so lots and lots of long triangles. The inner skin was laminated, then foam attached. The corners were sanded back to give a smooth outside shape and the outer skin laminated. All the interior frames the spine and the deck sections were waterjet cut prepreg foam carbon panels. There was a bit of bending and twisting to get them to fit but they are generally quite flat. If you were to make the whole thing out of prepreg panels then I think the amount of curvature in something like a fireball hull or some sort of streached 3.7 hull would probably be feasible but I would want to put some thought into how to hold the panels to shape while the taped seams dried. The kind of wire stitching you would do with a ply stitch and glue would probably not work |

If it doesn't break it's too heavy; if it does it wasn't built right
