Hello
As the title says I have had some problems infusing flat carbon/aramid sheets. I am using glass as a mould so i can get as smooth sheet as possible.
I use EC mould clean > followed by Easy Lease x4 times. the sheet is 32cm X 26 cm and 160ml of resin was used.
After 1 hour or so i Lay:
- 1 Layer of 300gr Plain weave Carbon
- 3 Layers Of Kevlar 280 gr
- 1 Layer of the same Carbon.
-Peel Ply
-P3 Release film Perforated
- Infusion Mesh
- Resin infusion spiral
- Bagging film
Since i didn't have more resin infusion resin I used
EL2 Epoxy Laminating Resin
that i let it be heated by the sun for 1 hour. I could clearly see the the viscosity of the resin had changed. i For the Mix Ration I then used with 2/3 of AT30 Epoxy Hardener FAST in conjunction of the Slow hardener since i didn't know hoe fast the infusion process would take ( The infusion process took under 25 secs BTW).
The bag didn't had any leaks since i let it be for 1 hour.
Room temperature was close to 30 degrees and it never dropped to under 25 during Gelation time.
i demolded the sheet after 17 hours.
So where in the process did I go wrong ?
did I pull a too hard vacuum; should have used a Lossless vacuum regulator ?
or should i just leave it a full day or more before demoulding ?`
Any tip will be appreciated.
