With reference to given Example, 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

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 V_f = 0.6.

Sample A was fabricated under controlled laboratory conditions, resulting in a standard deviation of misalignment α_σA = 1.0° . Sample B was fabricated under normal processing conditions, resulting in α_σB = 1.7° .
