Get started for free(a) Cite several reasons why fiberglassreinforced composites are utilized extensively. (b) Cite several limitations of this type of composite.
(a) Write an expression for the modulus of elasticity for a hybrid composite in which all fibers of both types are oriented in the same direction. (b) Using this expression, compute the longitudinal modulus of elasticity of a hybrid composite consisting of aramid and glass fibers in volume fractions of 0.25 and 0.35 respectively, within a polyester resin matrix \(\left[E_{m}=4.0 \mathrm{GPa}\left(6 \times 10^{5} \mathrm{psi}\right)\right]\)
Briefly describe pultrusion, filament winding, and prepreg production fabrication processes; cite the advantages and disadvantages of each.
The mechanical properties of cobalt may be improved by incorporating fine particles of tungsten carbide (WC). Given that the moduli of elasticity of these materials are, respectively, \(200 \mathrm{GPa}\left(30 \times 10^{6} \mathrm{psi}\right)\) and \(700 \mathrm{GPa}\). \(\left(102 \times 10^{6} \mathrm{psi}\right),\) plot modulus of elasticity versus the volume percent of WC in Co from 0 to 100 vol\%, using both upper- and lowerbound expressions.
Briefly describe laminar composites. What is the prime reason for fabricating these materials?
