Hi,

I am presently working on the project 'FibreBlade'. I have manufactured Basalt fibre reinforced epoxy laminates with different stacking sequences, different angle-ply orientation. I am having some confusion related to one of my work:

• For my (90)16 unidirectional test specimens i am getting an average thickness of 6mm (including the standard deviation) approximately, whereas for my (90)10 unidirectional test specimens i am getting an average thickness of 3mm (including the standard deviation) approximately. Here, on changing the number of fibre layers to 10, i can see the thickness has changed to almost half as compared to the thickness measurement i was getting when i stacked 16 layers of basalt fibres to manufacture my test specimens. Theoretically, i am supposed to get a thickness measurement of approximately 4 mm on varying the stacking to 10 from 16. As 3 mm would have been perfect for a stacking sequence involving 8 layers. I am not being able to think about a proper reason for this variation. Any help will be really appreciated.
