Question

**figure screen shot attached**
A composite component (such as shown in Fig.2) is required for an aerospace application. The specification for the component stipulates that it must have an Elastic Modulus in the fibre direction of at least 320 GN/m2, and the transverse direction modulus must not be less than 8 GN/m2, but with a maximum permissible density of 1650 kg/m3. In order to determine if such a composite is possible:
i) Plot (preferably using excel), the composite modulus (Ec) versus fibre volume fraction (Vf) showing upper (isostrain model – parallel to the fibres) and lower (isostress model - perpendicular to the fibres) bounds for the Epoxy/Carbon-fibre composite (data are provided in Table 2);

ii) Estimate the carbon fibre volume fraction required to achieve the above specification.
(Hint from the plot in part i) find the Vf for the required modulus [320 GPa] in the fibre direction – upper bound line, then check if the lower limit is okay, finally workout the density of the composite to see if it is within the spec – also check your answer with calculations)

Answer 1

yes

Answer 2

Are you engineering student? if yes pls help me.

Answer 3

no but its a fifty fifty

Answer 4

PLs help me in detail.

Answer 5

@Vocaloid Please help me.

Answer 6

I believe the equation is 1200x1850 divided by 5 and then subtract 480 and there should be your answer

or science or anything

Answer 10

This is actually engineering, Materials and Manufacturing

Answer 11

ooh I thought it was math

Answer 12

sorry
