Bubbles, Voids and now Ripples???

I've had a lot of fun so far with making carbon blunders.

This weeks instalment features the use of the easy composites bristled roller as well as a heat gun with some interesting effects.

So last night after my new roller arrived I was keen to get on with casting another sheet of carbon. The garage was slightly cold so I decided to heat up my mould using a hot air gun till the mould was warm to the touch.

While laying the carbon each time I used the roller and made several passes.

While applying more epoxy for the next sheet I quickly passed over with the hot air gun and watched as alot of bubbles popped(awesome).

The final change I made this time was adding two extra layers to the stack so 9 x 650g 2/2 twirl. i guessed this would give me a finishing thickness of around 5.5mm once compressed and thought it may help push any bubbles out if I increased the compression force on the stack.

this is the end result. although beautiful not entirely perfect. anyone know whats happening here?

The end result seams to have a lot less bubbles in it. there is hardly any pinholes on the surface of both sides although there is some rippling going on. have i put to many layers in and squeezed to much. Thickness actually came out closer to 6mm.

any help/comments appreciated. gearing up for an infusion set up over the next month or two so more learning and blunders to come.

Hello its me again with some more noob questions on carbon.
