Hypothesis
The study aims to determine the impact of cell size and porosity on the thermal and mechanical properties of a 3D printed thermal insulation barrier.
Conclusion
The study found that 3D printed cellular composites can achieve very good thermal insulation properties, comparable to standard materials used in construction.
Supporting Evidence
- The best insulation results were obtained for composites with a cell height of 4 mm and a porosity of 90%.
- Thermal conductivity coefficients for the tested samples ranged from 0.037 to 0.052 W/(m·K).
- Compressive strength values were significantly affected by the porosity of the composites.
Takeaway
The researchers made a special type of insulation using 3D printing that works really well to keep heat in or out, and they found out how the size and holes in the material affect how well it works.
Methodology
The study used a two-factor three-level full factorial design to test different combinations of cell porosity and height, with samples printed from PLA and tested for thermal conductivity, thermal resistance, compressive strength, and quasi-static indentation strength.
Limitations
The study focused only on specific porosity and height combinations and used a single material (PLA) for the samples.
