Solve the following problem:
With reference to Example 1, select a different matrix in order to achieve a compressive strength of at least 1, 100 MP a. Assume that the standard deviation of fiber misalignment remains constant at the production value of 1.41 degrees. The fiber type and fiber volume fraction remain unchanged.
Example 1:
Estimate the effect of misalignment on the compressive strength of a carbon- epoxy (AS4-3501) composite fabricated by hand lay-up of prepreg tape, vacuum bagged and oven cured, resulting in a fiber volume fraction Vf = 0.6. Sample A was fabricated under controlled laboratory conditions, resulting in a standard deviation of misalignment ασA = 1.0°. Sample B was fabricated under normal processing conditions, resulting in ασB = 1.7°.
