QUESTION 9
A researcher is working on sustainable composites has developed an experimental composite (CFRP) that has a small amount of biodegradable
matrix. During a lab accident, they have lost some directional properties values that they have measured experimentally. However, they found their
notes that include information on the Poisson's ratio, the stiffness matrix, and the ratio of E2/E1. Using the information provided find the value of E1 in
GPa.
V12 = 0.34
E2/E1 = 0.13
Q11= 132.04 GPa
Q12=2.52 GPa
Q22=8.92 GPa
