So I am doing my first real pre-preg tool.  The mould I had made for me has had issues........ loads of stress cracks appeared after only a couple of pulls.. Not looking for answers or reasons why that mould has had issues. I got so pissed off that I looked into a dozen different things and all I got was dizzy with each person giving me a different reason.  So I took one I had made and lacquered it to get a good finish and to remove some of the raised areas where the original stickers got left on the tank when it was moulded.  I put it back into the mould and have started to remake the mould using pre-preg carbon tooling. So far it seems to be working.. I have done the top section already and although I have not removed the section from the part the flange areas look perfect and if the rest of the mould comes out the same way I will be happy. Having had numerous quotes to remake the mould for me including a quote from the person who made it in the first place (he seems to feel it is other reasons and not his work that has caused the problem). I have bit the bullet with some Tooling from SHD. 

I will post updates as I go and hopefully in a few days will have a finished working full carbon pre-preg mould. 

Hi buddy，I am from China, I like Honda motorcycle, Indonesian the latest new Honda CBR250RR, I plan to refit the motorcycle, especially part of the tank, for epoxy resin corrosion problem of petrol I have been online to find the problem, how did you handle it? Corrosion protection has been handled? There are layers in the tank, I expected placement 5 layer, a layer of the surface layer and four-layer volume level. For moulding process of carbon fiber and resin flow forming technology I am more skilled, I myself had a hand trolley, use the diversion process, produced, taking into account the wear problem, I spray a matte color car paint.
