Hello The question is about this product: https://www.easycomposites.co.uk/surplus-carbon-fibre-8hs-satin-weave-3k-366g
The description says that the fabric has unbalanced layup. I have read the spreadsheet and cant find out the exact dimensions of this. Direction and weights. Do yo have this info? 

In this case "Unbalanced layup" just means that there twice as many fibres going in the same direction in the fabric.
You can actually count this from the picture.

I have used this fabric and provided you can cut your shapes from the roll in  both directions i.e. across and along the roll, you will have a balanced layup anyway.
The fabric has most fibres going along the roll.

I have made semi large parts with this fabric, and two layers of this at 90 degrees is far stiffer and probably 50% stronger than two normal layers of Twill "Black Stuff"
