- 20. Raw Materials : A bulletproof vest consists of a panel, a vest- shaped sheet of advanced plastics polymers that is composed of many layers of either Kevlar, Spectra Shield The layers of woven Kevlar are sewn together using Kevlar thread, while the nonwoven Spectra Shield is coated and bonded with resins such as Kraton Army Applications : Bullet Proof Vest
- 21. The Manufacturing Process : 1. To make Kevlar, the polymer poly-para-phenylene terephthalamide must first be produced in the laboratory. This is done through a process known as polymerization, 2. The resultant crystalline liquid with polymers in the shape of rods is then extruded through a spinneret (a small metal plate full of tiny holes that looks like a shower head) to form Kevlar yarn. 3. The Kevlar fiber then passes through a cooling bath to help it harden. After being sprayed with water, the synthetic fiber is wound onto rolls. 4. The Kevlar manufacturer then typically sends the fiber to throwsters, who twist the yarn to make it suitable for weaving. 5. To make Kevlar cloth, the yarns are woven in the simplest pattern, plain or tabby weave, which is merely the over and under pattern of threads that interlace alternatively. Army Applications : Bullet Proof Vest
- 22. Its made out of an ultra-high- molecular- weight polyethylene (UHMWPE) fiber Army Applications : Spectra Shield
- 23. Aerospace Applications : Satellites
- 24. Aerospace Applications : Satellites The Properties Materials Need to Function in Space: 1. Dimensional Stability 2. Environment Stability 3. Strength and Stiffness 4. Versatile and unique in their integrity 5. Economically Viable (weight)
- 25. Chemical Composition : Kevlar is simply a super-strong plastic , It is made of paraphenylenediamine and terephthaloyl chloride. This combination creates aramid threads that are dissolved and then spun into regular fibers, which are woven into fabrics. The matrix for high performance composites is usually epoxy resin. Aerospace Applications : Kevlar Tensile Strength = 3,620 MPa
- 26. Advantages : • maintains its strength and resilience down to cryogenic temperatures (−196 °C) • High tensile strength-to-weight ratio (5 times stronger than steel) • Can resist attacks from many different chemicals Disadvantages : • it has very poor compressive strength Aerospace Applications : Kevlar
- 27. Fiber Reinforced Concrete (FRC) Reinforcement • Glass fibers • Steel fibers • Polymeric fibers
- 28. Construction Applications : Chemical Composition of FRP Fiber-reinforced plastic is a composite material made of a polymer matrix reinforced with fibres.

Editor's Notes
- #24: We rely on satellites and structures in space for communications more than ever before. They help provide us with television pictures, telephone calls and a wide variety of communication signals, whilst surviving the hostile environment of space. The materials used in space are, more often than not, the most advanced materials that humans have created and we are constantly researching and creating new and improved materials.
- #25: 1- An Object that is continually moving in and out of the sun’s direct heat is in constant temperature flux, which can cause it to expand and contract. As a result, scientists consider a material’s ability to maintain its size and shape despite temperature changes. 2-the material can remain stable in despite the presence of radiation and the vacuum of space. 3-The launch alone can put a material under up to three times the force of gravity, meaning that each component will weigh up to three times as much as it would on Earth. The material must maintain its integrity and not break or bend under immense forces or the satellite will not function once it reaches space.
