Could you please answer this question sir? "When hand laminating UD semi-finished products, the following sequence of individual layers [0/-45/45/-90/0/0/-90/45/-45/0] was manufactured. In contrast, the original laminate should have had the layer sequence [0/-45/45/90/0/0/90/45/-45/0]. How does the processed sequence of laminate affect the material behaviors' when the laminate is loaded by external forces in the -45 degree direction? "
hi, great lecture. i wanted to ask if i have a bar of CFR PEEK that is made of laminat fibers angles 45 -+ in stacking , what theory and calculations shall i perform to gets its modulus .
