Hello,
I'm building some pregreg components as part of a university project. For brevity, I will skip details, I just tell you that so far I've built some "pipes" with a kind of D-section (and a taper angle to facilitate mould extraction). The picture shows the mould, the prepreg shapes and the final part.
Now, what I want to do is to attach 2 of those pipes together by placing them adjacent along the flat part and adding an outer layer of prepreg, like in this sketch:
My question is: can the two inner pipes go into the oven again? They already underwent a cycle of 4 hours (
1hr @ 50'C, 1hr @ 60'C, 1hr @ 70'C, 1hr @ 120'C). I'm using Easy-Preg 240g 3K Surfacing Prepreg and Vari-Preg 400g 12K.Backing Ply. I wonder if the mechanical properties deteriorate after a second cycle like that.
