Here,
+ vf: fibre volume fraction
+ Ecr: Elastic moduli contrast, the ratio of fibre elastic moduls to that of the matrix
+ Each of the label arrays contain 8 columns, which are
	+   column index 	=> 		label
		`0 				=>    Vf`, Fibre volume fraction
		`1 				=>    Em`, Matrix elastic modulus
		`2 				=>    NUm`, Matrix Poisson's ratio
		`3 				=>    Ef`, Fibre elastic modulus
		`4 				=>    NUf`, Fibre Poisson's ratio
		`5 				=>    E22/Em`
		`6 				=>    E33/Em`
		`7 				=>    G23/Gm`
