Group: Forum Members Posts: 27, Visits: 123	Hi everyone. I am in the middle of my first carbon project which is linked to here: http://frankiepix.de/carbon-front-fender-701-supermoto/ The project is blogged in German, but I think that google can translate it very easy. Though I am German, I would be very happy for every hint I can get. Regards Frank

Group: Forum Members Posts: 27, Visits: 123	+x Hanaldo - 11/23/2018 1:32:09 PM Standard behaviour for wet resin in contact with a mould surface that has been treated with a chemical release agent. The chemical release agents lower the surface energy of the mould so much that the resin can't 'cling' to it, and so the resin tries to form a shape that has minimal surface contact: a sphere. You mean another try without EasyLease and Meguiars wax instead of it would help? Frank

that looks like a really overly complicated mold for such a "simple* geometry. awesome work tho!

Forget the Uni-Mold kit if your going to make it with pre peg and cure it in an oven as the max temp is 80c .

something went wrong... can the mould be too good released? Frank

Well, perhaps. But I would suggest switching to a more advanced process, like resin infusion or pre-preg. Or at the very least, wet-lay vacuum bagging. You really need some sort of consolidation to.....

After i failed with the first part, i would like to start a second try with resin infusion. Here are some Pictures of the Mould: The mould is about 85 x 25 cm. Picture 1 side view It ist a four-par...

The vacuum leakage drives me crazy... I bagged the whole Mould. It took me over 4 hours and the bagging was still not properly sealed. I gum-taped all nuts and bolts, every edge, I used 1/2 can...

My opinions: -You really should have made the mounting section separately. This would have been one of the easiest projects you can think of. -to get the cloth in wrinkle free (assuming one fibre...

@oekmont The mounting section is not my biggest problem in the moment. And: the mounting section is already part of the mold. I fill it with a mixture of chopped carbon fibre strands and resin. That...

So, finally I produced a nearly error-free Part. Just some tiny pinholes, which are now filled with grinding-dust. I hope they will dissapear by polishing them with the black NW1. Frank

The fourth demoulded component is in order but can be improved. 1. Fault inside 2. Wall thickness in corner 3. Air bubble in the assembly area 4. Pinholes 5. Visibility of the mounting layer....

Looks very good i would say. I think cutting the fabric at 45° would make things worse as it is going ot move around more but you still need to get in the corners just right. I assume you are using a...

SleepingAwake - 8 Years Ago

For the last front fender, I did not fill the mounting area (picture 3, first page) with chopped carbon fibre thickened resin as usual, but rather with dry carbon fabric. Just as the rest of the mold...
