A fiber reinforced composite contains e-glass fibers in an epoxy matrix. E for the glass is 72 GPa, E for the epoxy is 2.4 GPa.
Ronch [10]

Answer: hello your question is in complete  below is the complete question

A fiber reinforced composite contains e-glass fibers in an epoxy matrix. E for the glass is 72 GPA, E for the epoxy is 2.4 GPa. Find the elastic modulus of a composite that contains 5% fibers in the longitudinal direction, Ecl = ViEi + EmVm? (note Vi + Vm= 1.) O 5.88 GPa O 5.66 GPa O 2.52 GPa O 6.74 GPa

answer : 5.88 GPa

Explanation:

Fiber reinforced composite containing e-glass fibers

E for the glass ( Ei ) = 72 GPa

E for the epoxy ( Em ) = 2.4 GPa

<u>Determine the Elastic modulus of a composite containing 5% fibers </u>

percentage of glass = 5% = Vi = 0.05

∴ percentage of epoxy = 95% ; Vm = 0.95

using the relation included in the question

Ecl = Ei Vi + Em Vm

    = ( 72 * 0.05 ) + ( 2.4 * 0.95 )

    =  3.6 + 2.28  = 5.88 GPa

What is a disadvantage of using a space-filling model to show a chemical compound?
Pavlova-9 [17]

Answer:

Explanation:

The appropriate answer is 'space filling models do not identify the number and type of bonds'. A space filling model is one type of three dimensional (3D) molecular model used to represent molecules of different chemical compounds. The structure of this type of arrangement shows that, for example, two elements are bonded but it does not show if it is a single, double or triple bond.
