Hi , whats the epoxy amount for

300g diolen                                        

3mm Soric    

all so i have the breather cloth in my infussion kit,but its not mensioned in the video?  do i use it ?

i have a male corner in my mould and have cut the material to fold around it, is it possible to tack down the skicky out bits within the mould, if so what with? 

i am using wax ontop off a pva (polyester resin mould) as a release will this be ok

 

many thanks  

Hi, Jack.

For the amount of resin, you can calculate approximately like this:

People usually want a 60/40 reinforcment/resin ratio. So, for your 300 g/sqm diolen, it would be 120 g resin per sqm, PER LAYER of cloth.

For the 3mm thick soric, EC website says it takes 1.3kg per sqm.

You then need to calculate how much sqm you have on your part, and deducting how much resin you will need regarding how many layers of cloth/soric you are using. It's always a good idea to mix a little more resin than theorically, depending which process you choose (hand layup or infusion). Typically, hand layup will take more resin than infusion.

If you are using resin infusion process to make your laminate, you wont need breather cloth. Infusion stack with soric would be mold surface/reinforcment/soric/reinforcment/vacuum bag, as mentioned on EC website.

Breather cloth would be usefull for vacuum bagging a hand wet layup. It would act as a "excess resin catcher" thru  perforated release film.

Also, if you are making a cored composite, you will want it to be balanced, which means you have to put equal layers of same cloth on each side of the core. Example: 2 layers 300g/sqm diolen then soric then 2 layers 300g/sqm diolen. This would ensure the part would not deform during cure.

I hope it helped.
