As expected the pull off the breaker roof has something in the rain gutters which I missed when cleaning.
A few spots on the mould needed cleaned then repairing which not ideal but is fine for a test piece and I will vinyl wrap the part next time.
Usual chemical release agent was added in 4 layers then 8 layers of the release wax.
Which brought us to the point of actual layup of the fabric this is where you can tweak your layup to be stiffer or more flex.
By how much depends on the stack an
The test part for top was
x1 210 gsm 2x2 twill
2mm Soric foam core
This foam has small hexagonal chambers that fill up with resin during infusion and helps as a flow medium too, increases strength but also increases weight.
x2 210 gsm 2x2 twill
On top of the dry fabric had peel ply and the infusion mesh as a flow medium.
Since its quite a large part you want to create a minute space for the resin and air to flow.
1 inlet and 1 outlet will still have 1 side draw more vac than the other so a flow mesh creates better channels.
I like to envelope bag the part for infusion to avail any chasing small leaks, (hearing is not what it used to be), this is more materials but higher success rate
1400cm x 900cm poly bag with bagging tape which is basically like Blu Tac
Pierce bag and add in 6mm tubes for resin lines, crossing your fingers you dont puncture the bag too much and rip the hole.
Pull full vac and leave for a while to do a drop lest, then if all good start infusion.
I used the Easy composite IN2 infusion resin with the Slow hardener since it's a big part can take about 40 mins to infuse a slower gel time for resin lets you get it completely infused before it starts to gel and stop flowing. You can clamp the lines to reduce time further aswell if needed.
Infusion was success now to leave it to cure for 24 hours.
