Done By Group : JBH_Top8 School Name : Jassim Bin Hamad Independent Secondary School. Composite Material Module:through our activities with Albairaq we learned that the composite material can be defined as a mixture or combination of two or more material , we did many activities to test some properties for composite materials like stiffens and strength. Our Idea is :Making a along life bag using a composite material, This composite is consist of 4 materials in lyres: 1- A RUBBER COVERS THE OUTER AREA TO ABSORB SHOCKS 2- STRONG STEEL WIRE MESH WILL SUPPORT THE INNER STRUCTURE OF THE BAG. 3- A STRONG PLASTIC LAYER WILL BE IN BETWEEN 4- Cloth lyre inside the bag to protect clothes

• Introduction
• Activity 1: testing different kind of ice.
• Activity 2: Hunting for composite materials.
• Activity 3: Exploring the Deference Between
• Strength and stiffness.
• Activity 4:Testing a foam composites for
Strength and Stiffness.
• Design Project : Designing a fishing pole

3. INTRODUCTION
A composite material can be defined as a mixture or combination of •
two or more material.

4. ACTIVITY 1: TESTING DIFFERENT KIND OF ICE
• We made 3 samples of ice:
• 1-Water only.
• 2-water with tissue paper.
• 3-water with cotton.
We found that ice composite that made with tissue
paper and Cotton is stronger than ice made with water only

5. ACTIVITY 2: HUNTING FOR COMPOSITE MATERIALS.
We looked around us to find composite materials. •
Tennis rackets are
made out of
composites
Car wheels are
made out of
composites
Plywood is a
composite of wood
lyres

6. ACTIVITY 3: EXPLORING THE DIFFERENCE BETWEEN STRENGTH
AND STIFFNESS.
- Strength :is the amount of force needed to break something.
- Stiffness is : Not easily bent or changed in shape; rigid.
We tested some materials for strength and stiffness :
pasta ,iron ,nylon ,wood ,plastic .

7. ACTIVITY 3: EXPLORING THE DEFERENCE BETWEEN
STRENGTH AND STIFFNESS.
We ranked the materials from strongest to the weakest

2-Beam with one side paper
3-Beam with two side paper
4-Beam with disjoint

10. DESIGN PROJECT: DESIGNING
A FISHING POLE
We made our design using wood
difference velocity Weight
0 gm. 10 cm. 0 cm.
Scales 12 cm. 2 cm.
200 gm. + scales 14 cm. 4 cm.
400 gm.+ scales 16 cm. 6 cm.
600 gm.+ Scales 20 cm. 10 cm.
It break after 600 gm weight

11. DESIGN PROJECT: DESIGNING A FISHING POLE
We made our design using Thread
difference velocity Weight
0 gm. 10 cm 0 cm.
15 gm. 25 cm Scales
It break after hanging the scale, it was week

12. OUR IDEA:
LONG-LIFE BAG
THE IMPORTANCE: •
TO KEEP LUXURY GOODS AND FRAGILE AWAY OF DAMAGE USING STRONG •
LIGHTWEIGHT CASES .

13. LONG-LIFE BAG
METHODS AND MATERIALS
FORMATION :
USING A COMPOSITE Material
This composite is consist of 4 materials in lyres:
1- A RUBBER COVERS THE OUTER AREA TO ABSORB SHOCKS
2- STRONG STEEL WIRE MESH WILL SUPPORT THE INNER STRUCTURE OF THE
BAG.
3- A STRONG PLASTIC LAYER WILL BE IN BETWEEN
4- Cloth lyre inside the bag to protect clothes.

14. ACKNOWLEDGMENT
Many thanks to our teachers, school and AL-Bairaq team
from Center for Advanced Materials (CAM), Qatar University
for supporting us during our journey with a AL-Bairaq.
Also, I would like to thank the sponsors UNESCO, Ras Gas,
Maersk Oil and Shell.
