Resin calculation?

Resin calculation?

(OP)
Hi guys,
I just started a job in the composite industry and I have to give a BOM for every item used on a part. My question; how do I calculate how much resin to use on a surface area? I have a surface area of 592.45^2 and I need to have a bond line of .005. I use Solidworks at work so if that helps in any way please let me know.

Thanks
 

RE: Resin calculation?

Hmm, what is the resin used for? surface filler?  What do you mean by "bond line" for surface resin?

Quantity (by weight) should just be volume (area x thickness) times density (get it from the supplier's data sheet) times a factor to account for excess,, wastage, etc (maybe 2X - 10X) depending on the answers to the above questions.

The word bond line is usually referred to when joining prefabricated composite parts together, i.e. a glue joint.
  If you are doing a lay-up then you would calculate the amount of cloth plus the resin. This will vary depending on the desired resin cloth ratio, the weight of cloth per sq ft and the density of the laminating resin..
 Example : cloth .8 oz per sq ft, resin .6 oz per sq ft, total 1.4 oz per sq ft. Approx laminate thickness .015"per sq ft, this is for a hand laid wet resin system. If you are using a prepreg the manufacturer will give you those numbers. Tell us what you want to do and you will get more sensible answers.
B.E.

Sorry if I didn't make a lot of sense. Working on a dead line time. But I'm just trying to calculate resin usage being calculating for wet lay up or joining (bonding) together components. I guess what I'm really looking for is an easy and fast way of calculating. Both SWcomposite and Berkshire answers have been helpful, thanks for the quick response.
