Hypothesis
Can a hybrid composite made from polypropylene, polybutadiene, glass fibre, and flax fibre improve mechanical and thermal properties?
Conclusion
The study found that the new hybrid composite significantly improved tensile strength, flexural strength, and thermal resistance compared to pure polypropylene.
Supporting Evidence
- The tensile strength of the hybrid composite increased by approximately 24% compared to pure polypropylene.
- Flexural strength improved by about 15% in the hybrid samples.
- The hybrid samples showed higher heat deflection and Vicat softening temperatures than standard polypropylene.
Takeaway
The researchers created a new type of plastic that is stronger and can handle heat better by mixing different materials together.
Methodology
The researchers used twin-screw extrusion and compression moulding to create polymer blends and composites, testing their mechanical and thermal properties.
Limitations
The study acknowledges challenges in recycling due to the use of glass fibre.
