Composite materials (also called composition materials or shortened to composites) are materials 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. This is an extremely broad definition that holds true for all composites, however, more recently the term "composite" describes reinforced plastics. This program will explain how composites work and what the future holds for these amazing materials.

Perhaps no invention has impacted our everyday lives more than the computer. Computers have transformed the fields of sci- ence, medicine, education, entertainment and research, to name a few. In fact, it's hard to think of any area of our everyday lives that has not been affected by computer technology. Computers have become an indispensable part of our lives. A computer is made up of Hardware, the machine, the hard drive, the boards and chips, which take instructions from Software - or applications. The result is a completed task, or epic graphics in a game or pin-point accuracy in a robot assisted medical procedure. From a steam-driven prototype developed in the early 1800s, to the first computer built in 1941, which could process 29 equations simultaneously, to the microprocessor developed by Intel - the evolution of the computer is amazing. The first computers, developed in the mid 1940s took up an entire room. Today the microprocessor, smaller than a fingernail, delivers immense computng capabilities to run today's applications.

People have a lot of different ideas about what the future will be like. Will there be flying cars? Will people live on the Moon? One thing that most people agree on is that robots will probably be very important. So lets have a look at robots - how they work, how theyre made and how theyre going to change the world. Robot technology is already changing our World.
This program provides an easy-to-understand introduction to the history and applications of robots, along with the basic principles of robot Control Theory and engineering. Robots are some of the most complicated machines to have ever been made, but the basic principles of how they work can be quite easy to understand. Robot designs can be broken down into two different general types: Open Loop and Closed Loop. Open-loop robots repeat the same sequence of pre-programmed actions, no matter what. This type is commonly used by industrial robots, or other robots that only do one job in a very structured environment. They can be very easy to make, since they only do one thing. Closed-loop systems are much more complicated. Instead of just going through a list of pre-programmed actions, the robot looks at the world around it and changes its behavior depending on what it sees. Subjects covered include: A brief history of Robots, how Robots work, types of Robots, the Future of Robots.

According to ABET, or the Accreditation Board for Engineering and Technology: "Engineering is the profession in which a knowledge of the mathematical and natural sciences, gained by study, experience, and practice, is applied with judgment to develop ways to utilize, economically, the materials and forces of nature for the benefit of humankind." There is considerable overlap between science and engineering. Research teams often consist of one or more engineers who work closely with scientists to design and build some of the tools required for lab experiments or to test theories in practice. Engineers are motivated to improve our quality of life; here are some examples: making renewable energy economical, improving health informatics, making better medicines, improving automobile safety, and improving urban infrastructure. Engineers typically develop new products using several steps - Design phase, testing, production and maintenance. During the design phase, engineers specify the functional requirements; design and test the components; produce a prototype; and evaluate the overall effectiveness, cost, reliability, and safety. This process is common in the development of many different products such as chemicals, computers, energy sources, and transportation. During testing, production and maintenance, engineers determine if any failures of the components are likely and where they occur. This is where they estimate the time and cost required to produce a product. In these processes, engineers use computers to create designs, analyze functionality, and simulate how a machine, structure, or system operates.

Engineers are constantly developing new lightweight, durable textiles to be used in many facets of our daily lives. Manufacturers of airplanes and automobiles are increasingly turning to textiles, such as carbon fibers, to produce their new models. They rely on carbon fibers due to light weight and durable properties. For instance, the wing of an airplane might be metal, but many of the interior parts are made of carbon fiber. Aircraft engineers combine carbon fiber with other lightweight materials to create composites which are usually 20 to 30% lighter than metal alloys. Carbon fiber threads are made up of between 1,000 and 48,000 tiny filaments. The filaments are created by oxidizing, or burning a synthetic polymer in a 2000 degree furnace, turning it into almost pure carbon.
Engineers are finding uses for new high tech materials, such as QTC - a polymer embedded with millions of tiny pointed metal particles. QTC acts like a resistor, but the metal particles are so close together, that if something in the environment changes, the charge between particles increases and electrons can jump from one to another in a process called quantum tunneling. QTC is so sensitive that its resistance will alter if there are changes in sound, smell, temperature, or pressure. In future space missions, QTC might assist astronauts with fans, lights and other devices inside of their spacesuits - controlled by so called soft switches - devices that make use of the fact that QTC becomes more conductive when pressure is applied.
