Done by: Destroyers group School Name : Tariq Bin Ziyad Independent Secondary School for Boys. Composites Module : Students discover what composite materials are and test them to learn their advantages over pure materials. Finally, at the end of the workshop, they design new composite materials. The product Idea: Owing to the high temperature in Qatar, we decided to make use of composite material in manufacturing car cover using the following material in composites:Fabric, Nylon, Helium, Normal cover.

- 1. AL-Bairaq I am Discovering Materials Composites TBZ-Destroyers Mohammed Saffar Hussein Nizar Hassan Al- sharshani Abdurrahman Al-Emadi
- 2. Outline • Introduction • Activity 1: Testing Different kind of Ice • Activity 2: Hunting for Composite Materials • Activity 3: Exploring the Difference Between Strength and Stiffness • Activity 4: Testing a Foam Composite for Strength and Stiffness • Design Project: Designing a Fishing Pole • Product Idea
- 3. Introduction • A composite material is made by combining two or more materials to give the composite unique properties. Composites do not dissolve or blend into each other.
- 4. Activity 1: Testing Different kind of Ice • Objectives – Testing 3 samples of ice composites • Water only • Water and tissue paper • Water , cotton , newspaper and straws
- 5. Procedure
- 6. Results • We found that the composite made of ice, cotton , straw and newspaper was stronger than ice alone
- 7. Activity 2: Hunting for Composites • Objectives – We conducted an internet study to know more about composites.
- 8. Composites Types Properties Examples Particle composites Stronger , cheaper concrete Laminar composites Flexible, light weight plywood Reinforced composites Lighter, stronger and stiff material Material used in tennis racquet
- 9. Activity 3: Exploring the Difference Between Strength and Stiffness • Objectives – Test different materials like pasta , iron , nylon , wood , plastic. – Predict the ranking of the above materials for strength and stiffness.
- 10. Results Material to be tested Prediction about strength Prediction about stiffness Ranking from strongest to weakest Ranking from stiffest to flexible Iron rod 1 2 1 2 nylon 2 3 2 5 plastic 4 4 3 4 Wood 3 5 4 3 pasta 5 1 5 1
- 11. Activity 4: Testing Foam Composite for Strength and Stiffness • Objectives – Test 3 types of foam • Plain foam • Foam reinforced from one side • Foam reinforced from two sides
- 12. Procedure
- 13. Results Mass (g) Deflection in Plain foam(cm) Deflection in 2-side foam(cm) Deflection in 1-side foam(cm) 0 0 0 0 100 0.2 0 0.6 200 0.5 0.4 1.2 300 0.7 0.8 1.8 400 1.3 1.3 2 500 1.9 1.7 2.4 600 3 2 2.7
- 14. Conclusion • We found that 2- side foam reinforcement showed high property of strength and stiffness. • It showed less deflection for higher mass.
- 15. Design Project: Designing a Fishing Pole • Objectives : – Design a fishing pole, made out of a composite material that is based on plastic straw.
- 16. Procedure
- 17. Results Mass (g) Length(cm) Deflection 0 13 0 50 14 1 100 14 1 200 15 2 250 15 2 300 16 3 400 17 4 450 17.5 4.5 500 17.5 4.5 600 19 6 700 19.5 6.5 900 21 8 1000 22.5 9.5
- 18. Conclusion • We used plastic straw ,wood ,paper , cotton and wire as composite to make fishing pole to make it more flexible and strong which are the characteristics of fishing poles • Hence more weight could be handled using composite material.
- 19. Heat – resistant car cover Project Idea
- 20. Heat resistant car cover • Owing to the high temperature in our country, we decided to make use of composite material in manufacturing car covers. • We use the following material in composites: – Fabric – Nylon – Helium – Normal cover
- 22. Conclusion • Applications and Advantages – Our project helps people to reduce accidents caused by overheating in cars during summer. – Also it cautions other drivers when parked at night due to its fluorescent property. – Our design is highly economical , and environmental friendly.
