2. • Introduction
• Activity1: Testing different kinds of ice
• Activity 2: Hunting for composite Material
• Activity 3: Exploring the difference between strength & stiffness
• Activity 4: Testing a foam composites for strength & stiffness
• Design Project: Designing a fishing pole
• Product Idea

3.  A composite material: a material made
from two or more constituent materials with
significantly different physical or chemical
properties that, when combined, produce a
material with characteristics different from
the individual components. The individual
components remain separate and distinct
within the finished structure. The new
material may be preferred for many reasons:
common examples include materials which
are stronger, lighter, or less expensive when
compared to traditional materials. There are
many different activities that can explain the
composite materials.

4. Procedures: in three petri dishes put:
Ice only, Ice plus tissue, Ice plus tissue plus cotton.
• The ice + tissue + cotton is stronger than the ice alone and the
ice + tissue.

5.  The earliest man-made composite materials
were straw and mud combined to
form bricks for building construction. Ancient brick-
making was documented by Egyptian tomb paintings.
 Wattle and daub is one of the oldest man-made composite
materials, at over 6000 years old.[2] Concrete is also a
composite material, and is used more than any other man-
made material in the world. As of 2006, about 7.5 billion
cubic metres of concrete are made each year—more than
one cubic metre for every person on Earth.
 Woody plants, both true wood from trees and such plants
as palms and bamboo, yield natural composites that were
used prehistorically by mankind and are still used widely
in construction and scaffolding.
 Plywood 3400 BC by the Ancient Mesopotamians; gluing
wood at different angles gives better properties than
natural wood

7.  The first type is going to be only foam without any kind of reinforcement.
 The second type is a foam with a thick paper glued to one side only.
 The third type is a foam with a thick paper both glued from the top and
bottom.
In this activity we test three types of foams for their strength and stiffness.

8. • The aim: Designing a fishing pool with composite materials to achieve strength,
light weight and the maximum flexibility.

9.  Introduction
Electromagnetic interferences are signals emitted by electrical
circuits which are under operation, perturb proper operations of
surrounding electrical equipment or cause radioactive damage to
living / biological operations.

10.  The extensive development of electronic systems and telecommunications has lead to major
concerns regarding electromagnetic pollution. The quest for materials with high efficiency to
mitigate the high electromagnetic interference (EMI) pollution has become a mainstream field
research.
 The EMI shielding of electronic devices and/or radiation sources may be a consideration in the
reliable operation of devices, and possibly in preventing human health risks.
 Thin film attachment or spray coating of metal, conducting polymers, and carbon black
particles on a product surface shield the product from electromagnetic waves. Metal serves as
an effective shielding material because of its high conductivity, but metal adds significant
weight and corrosion issues. Conducting polymers and carbon particles are lightweight but
their conductivity is not as high as that of metal.

11. 1. Protecting the surrounding environment from (EMI).
2. Avoiding negative effects on any living organism .

12.  The assume of this project is the cover of the phone and the
charger will block the (EMI) from damaging the environment
surrounding it.
THE ASSSUMED RESULT OF THE PROJECT:

13. •Carbon black (CB) is a material produced by the incomplete combustion of carbon-containing
materials, such as oil, fuel oils or gasoline, coal, paper, rubber, plastics and waste material.
• It represents an excellent reinforcing filler used in rubber compounds thanks to their beneficial
impact on durability and strength.
•Titanium: presents an effective shielding material because of its high conductivity
•Low Density Polyethylene (LDPE): is a thermoplastic made from the monomer
ethylene.
•Melt-mixing the ingredients and shape in a mobile cover mold

14.  Preventing all hazard coming out of electronic devices
 Saving humanity from diseases caused by Electromagnetic radiations

15.  Carbon nanotubes may offer an alternative for EMI shielding due to their
light weight, corrosion resistance, and high conductivity

16. Composites enhance the properties of materials and help manufacturing
much more applications that benefits the world
We managed to make our own activities and learned from the experiments
results. We are able to invent, create, and make a positive effect to the
society
Electromagnetic radiations are very dangerous for our lives, composites can
fine many answers to this problem, we just found out one of the answers.

17. Many thanks to 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, Qatar National Commission,
Ras Gas, and Shell.
