Undirectional Fiber-eppxy-matrix composites are made with equal volumes of fiber and epoxy. Esitmate the longitudinal and transverse Moduli and strength of each of the composites using E-glass, graphite-HM, KEvlar 49, Kevlar 149 fibers with the epoxy matrix.
Solution
Solution:
Composites are anisotropic in nature; they possess maximum strength and stiffness modulus in the direction of the fibre orientation and minimum properties along the perpendicular direction of the fibre orientation.
In this example, epoxy is used as the matrix or continuous phase and different fibres are used, since no data is mentioned, the method of calculation is shown in this solution by taking example of Kevlar
Kevlar-49-Epoxy stiffness calculations:
Properties of Kevlar: Young
.
Measures of Dispersion and Variability: Range, QD, AD and SD
