Hi. Work in progress. Doors for Sky 34 coupe.
Vacuum infusion. 1 layer carbon fiber + 6 layers basalt fiber.
Hardened - 70°c, 3 hours.
That’s nice. What is the weight of an original door and your new carbon door?
Love it… keep up the good work, I am also interested in your weight savings
The indoor part of door was made with one piece of cloth?!
As I say every time you post on talkcomposites, amazing work! I revisit your thread on that site all the time for inspiration. Love the work.
original door(empty)- 18kg, carbon door- 5,5kg
3 piece of fabric. The Central part, and flanks
Thanks !
You dont leave yourself much room on the flanges!!
What do you use as the transfer medium? Very nice finish
flanges normal )
transfer medium- conductive mesh, like all
How did you make the molds?
1 layer of gel coat (epoxy), 4 layers of glass fabric (780gr.m). On epoxy resin.
Pahanes,
I hope you don’t mind me asking more questions.
When creating the molds how did you keep the inside and outside of the door separated?
Also for the inside of the door, where there were cutouts in the sheet metal how did you keep the form of the door?
Again great work!
Cutouts in the sheet metal- taped.
“When creating the molds how did you keep the inside and outside of the door separated?” - not understand the question) Molds are made as usual, not any tricks.
Canyon, I suggest you watch the Easy Composites video series on YouTube of how to make a bonnet. That will answer all your questions and is a great guide for 2 part moulds.
Pahances, sorry to reference something on the other thread, but you’ve build the doors, trunk, hood, and wing your car. For the wing, I know that you showed halves of the wing on the other site, but was that a copy of a form/wing that you bought? Or was that an original creation? Btw, what is the next project for your skyline?
This is great! What I have seen on many two part body panels ( inner support structure, and outer shell) is many people don’t get the correct laminate thickiness, resulting in a too thick seam area. I’m not saying that is happening here… I can’t see from the photos. The cosmetic fiber lay up looks very good though.
Someone with experience… what good is Basalt, and what are it’s characteristics in a laminated composite?
I’ve used basalt to make heatshields before, as it has exceptional heat resistance (can handle 1000 degrees C, if you can find a resin system 
). It is not quite as stiff as carbon fibre, but stiffer than fibreglass. Looks very nice too, so I sometimes use it when carbon fibre would be overkill.
Form of the wing are made with the original. Then manufactured the infusion.
Next job for Skyline probably hood with duct.
Black basalt in the resin, but this is superiority. Glass fabric and carbon stronger basalt. First time are made with basalt, it is an experiment.
Laminate, yes good )
