The reinforcement architecture determines how constituent properties are translated into a useful ply description. In this exercise you will inspect the selected architecture, compare the supplied examples and then make a controlled change to discover which aspects of the effective response are sensitive to that description.

Prepare the baseline
Read the constituent and architecture inputs before comparing the property cards. Use the paired example where the task specifies one, and note every difference between the two starting records. Then vary only the requested fraction or architecture parameter, rerun, and compare directional moduli and shear properties at the same units and reference state.
Worked procedure
1. Open Micro and inspect the supplied architecture, composition and constituent sources.
2. Compare warp fractions 0.4, 0.5 and 0.6 at fixed total reinforcement. Then vary architecture efficiency from 0.85 to 0.95.
3. Save each result as a separate composite material and compare the elastic property cards. Do not treat predicted stiffness as measured strength.
Review checkpoints
Existing exercise records are unchanged; these are additional studies.
Predicted stiffness is not measured strength. Existing example strengths are illustrative teaching inputs only.
Model limits
Teaching-only constituent/architecture assumptions. Elastic screening; no qualification, processing prediction or measured composite strength.
Interpret the comparison
Describe the change as a property prediction for the selected architecture, not as an observed manufacturing result. When saving a composite material, inspect the resulting independent snapshot and its unpredicted fields. Retain the recipe and input values as well, so that the origin of the snapshot remains understandable.
