fibrous reinforced composite

16.14   A continuous and aligned fibrous reinforced composite  having  a  cross-sectional  area  of 970 mm2  (1.5 in.2) is subjected to an exter- nal tensile load. If the stresses sustained by the  fiber  and  matrix  phases  are  215  MPa (31,300 psi) and 5.38 MPa (780 psi), respec- tively, the force sustained by the fiber phase is 76,800 N (17,265 lbf), and the total longi- tudinal composite strain is 1.56 X 10-3, then determine

(a)     the force sustained by the matrix phase

(b)     the modulus of elasticity of the compos-

 

are  33.1  and  3.66  GPa  (4.8 X 106

and

ite material in the longitudinal direction, and

 

5.3 X 105

psi), respectively. If  the  volume

 

fraction of fibers is 0.30, determine the mod- uli of elasticity of fiber and matrix   phases.

16.11   (a) Verify that Equation 16.11, the expres- sion for the fiber load–matrix  load  ratio (Ff IFm), is valid.

(b)     What is the Ff IFc ratio in terms of Ef, Em, and Vf?

16.12   In an aligned and continuous carbon fiber-

(c)     the moduli of elasticity for fiber and ma-

trix phases.
