4.2. Experiment #1-#5: Tensile Strength Testing [Seshat's Diamond Composites] First Scientific Experiments Ever

4.2. Experiment #1-#5: Tensile Strength Testing

Experiment #1: Tensile Strength at High HDCNS Concentration

Objective:
To measure the tensile strength of Seshat’s Diamond Composites at a high concentration of Hemp-Derived Carbon Nanosheets (HDCNS) and observe its effect on flexibility and failure strain.

Hypothesis:
Increasing the concentration of HDCNS will result in higher tensile strength but reduced flexibility, with lower elongation at break.

Materials:

• HDCNS: 70% concentration by weight
• Hemp Oil: 15% concentration by weight
• Hemp Lignin: 15% concentration by weight
• Tensile testing machine
• Sample molds (standard dog-bone shape for tensile testing)

Procedure:

1. Prepare a mixture of 70% HDCNS, 15% hemp oil, and 15% hemp lignin.
2. Mix components thoroughly and pour into molds.
3. Cure the samples in an oven at 120°C for 4 hours.
4. After cooling, prepare the samples for tensile testing.
5. Perform tensile tests at a controlled rate of 5 mm/min on the tensile testing machine.
6. Record the maximum tensile strength, elongation at break, and Young's modulus.

Data Collection:

• Tensile strength (MPa)
• Elongation at break (%)
• Young’s modulus (GPa)

Conclusion:
Analyze the data to determine whether higher HDCNS concentrations lead to increased tensile strength but decreased flexibility.

Experiment #2: Tensile Strength at Low HDCNS Concentration

Objective:
To measure the tensile strength of Seshat’s Diamond Composites at a low concentration of HDCNS and observe the impact on tensile performance and ductility.

Hypothesis:
Lowering the concentration of HDCNS will decrease tensile strength but improve flexibility and elongation at break.

Materials:

• HDCNS: 30% concentration by weight
• Hemp Oil: 35% concentration by weight
• Hemp Lignin: 35% concentration by weight
• Tensile testing machine
• Sample molds

Procedure:

1. Prepare a mixture of 30% HDCNS, 35% hemp oil, and 35% hemp lignin.
2. Follow the same procedure as Experiment #1 for mixing, curing, and sample preparation.
3. Test the samples in the tensile testing machine under the same conditions.

Data Collection:

• Tensile strength (MPa)
• Elongation at break (%)
• Young’s modulus (GPa)

Conclusion:
Compare the results with Experiment #1 to evaluate the effects of lowering HDCNS content on material performance.

Experiment #3: Effect of Hemp Oil Concentration on Tensile Strength

Objective:
To determine how varying the concentration of Hemp Oil affects the tensile strength and flexibility of the composite.

Hypothesis:
Increasing the concentration of hemp oil will reduce tensile strength but improve flexibility and elongation at break.

Materials:

• HDCNS: 50% concentration by weight
• Hemp Oil: 30% concentration by weight
• Hemp Lignin: 20% concentration by weight
• Tensile testing machine
• Sample molds

Procedure:

1. Mix 50% HDCNS, 30% hemp oil, and 20% hemp lignin.
2. Follow the same procedure for mixing, curing, and testing as in Experiment #1.

Data Collection:

• Tensile strength (MPa)
• Elongation at break (%)
• Young’s modulus (GPa)

Conclusion:
Evaluate how hemp oil concentration impacts tensile properties and compare with earlier experiments.

Experiment #4: Optimizing Tensile Strength by Adjusting Hemp Lignin

Objective:
To optimize the tensile strength of the composite by adjusting the concentration of Hemp Lignin, which contributes to the material's rigidity and impact resistance.

Hypothesis:
Increasing the concentration of hemp lignin will enhance the composite’s rigidity, leading to increased tensile strength but reduced ductility.

Materials:

• HDCNS: 50% concentration by weight
• Hemp Oil: 20% concentration by weight
• Hemp Lignin: 30% concentration by weight
• Tensile testing machine
• Sample molds

Procedure:

1. Mix 50% HDCNS, 20% hemp oil, and 30% hemp lignin.
2. Prepare the samples as described in previous experiments and perform tensile tests.

Data Collection:

• Tensile strength (MPa)
• Elongation at break (%)
• Young’s modulus (GPa)

Conclusion:
Analyze how the increase in hemp lignin affects overall strength and rigidity, and identify the optimal lignin concentration for high-strength applications.

Experiment #5: Balanced HDCNS, Hemp Oil, and Hemp Lignin for Optimal Flexibility

Objective:
To create a balanced composite with equal concentrations of HDCNS, Hemp Oil, and Hemp Lignin, testing for both tensile strength and flexibility.

Hypothesis:
An equal balance of all three components will result in a composite with moderate tensile strength and high flexibility.

Materials:

• HDCNS: 33.33% concentration by weight
• Hemp Oil: 33.33% concentration by weight
• Hemp Lignin: 33.33% concentration by weight
• Tensile testing machine
• Sample molds

Procedure:

1. Mix equal parts of HDCNS, hemp oil, and hemp lignin.
2. Cure and prepare the samples for testing as in previous experiments.

Data Collection:

• Tensile strength (MPa)
• Elongation at break (%)
• Young’s modulus (GPa)

Conclusion:
Evaluate how a balanced mixture affects the material’s mechanical properties, providing a baseline for potential multipurpose applications.

Once these five experiments are conducted, the results can be compared to identify how different concentrations of HDCNS, hemp oil, and hemp lignin affect tensile strength and flexibility.
