Strengths & Limitations

Strengths

  • +Direct experimental comparison of different composite formulations.
  • +Inclusion of multiple mechanical property tests (tensile, impact, bending).

Limitations

The cost of carbon fiber can be a significant limitation for many design projects.

Reliability & validity

The use of ASTM standards for specimen preparation and testing contributes to the reliability and validity of the findings. Repeating tests on multiple specimens for each ratio would further enhance reliability.

Think critically

While carbon fiber offers superior strength, what are the trade-offs in terms of cost, manufacturing complexity, and environmental impact compared to fiberglass?
