Would I be better with Prepreg ?

Group: Forum Members Posts: 32, Visits: 132	OK...here is a part that I am making. Here is the mould. I did it with the EC gelcoat and paste for high temperature, anticipating that I could then use it for hand layup and prepreg. I am making my first part by hand layup (because I need to check all dimensions are good at the end). But man it was a mess with all the shapes...do you guys think that I would really be better with prepreg or would it be just as hard ? Thanks !

Would I be better with Prepreg ?

Damien - 5 Years Ago

Pre-preg would be easier to achieve a good result. In terms of lay up, you can actually use wet-lay in much the same way as pre-preg by creating what is called a 'wet-preg'. Basically just putting...

Hi Hanaldo, Thank you for your feedback ! I can have access to a fairly good oven, I may give a shot to the prepreg to see how it goes. But watching the EC video on out-of-autoclave prepreg, they.....

Damien - 5 Years Ago

No, that won't work. And if you might get it down the part will look horrible, because the fibres will be disoriented quite a lot. The main problem is the prismatic shape in the middle. Fibres which....

Thanks ! Now if I don't mind something that is not good aesthetically speaking, is it doable ? If not, do you think that I can use a single piece for the entire part except for that prismatic shape i...

As I would consider it possible done with infusion, it should be possible with prepreg with the help of a heat gun. I would definitely not do it. I would cut out the middle bump for the first layer,....

Yeh you just need to plan your overlaps correctly in order to not get a step in the laminate thickness. Doing this part in one piece without any joints in the material may be possible, but very very...

Hanaldo - 5 Years Ago

I agree with everybody who says don't try it in one piece! Hanaldo's idea of using a wet-preg method with plastic on both sides is what I'd do - especially if you don't have / haven't used pre-pregs....

Dear all, Thanks a lot for all your advices ! I did give a shot to OOA prepreg , and the results are stunning. First, it was so much nicer to manipulate...no epoxy and pieces of carbone fiber all...

Damien - 5 Years Ago

Yeh it's super tough to stomach going back to wet-lay after having worked with proper pre-preg. Hell, even infusion is just a bit unpleasant with all the extra consumables etc. Wait till you've trie...

Thank you!

Now except for paying attention when putting the release film as flat as possible, any other tip to limit the little "folds" of resin on the part that is not against the mould ? Thanks !
