Hypothesis
How does the addition of carbonisate affect the tensile properties of epoxy composites?
Conclusion
The addition of carbonisate significantly reduces the tensile strength and strain of epoxy composites.
Supporting Evidence
- The tensile strength decreased by 9% with 7.5% carbonisate and by 13% with 5%.
- SEM studies revealed cracks and delaminations in composites with carbonisate.
- Metric entropy calculations showed significant qualitative changes in the material structure.
Takeaway
Adding carbonisate to a composite makes it weaker, like adding too much sugar to a cake makes it fall apart.
Methodology
Static tensile testing and metric entropy calculations were used to analyze the properties of the composites.
Potential Biases
Potential bias due to the use of a single type of carbonisate and the manual preparation of samples.
Limitations
The study is limited by the manual lamination process, which may introduce defects.
