Composite Materials
1. Among the oldest and newest of structural materials are composite materials. It was discovered many years ago that two or more materials could be used together as one. Later it was proved that such a combination often behaved better than each material alone. Following this principle, clay and straw were combined to make bricks. For centuries composite materials remained virtually untapped. Only then monolithic materials, such as iron, copper were served for needs of an advancing technology. Recently it was a development of technology with coming of reinforced concrete, linoleum, plasterboard and plywood panels.
2. During the 1930s and 1940s light-weight honeycomb structures, machine parts made from compressed metal powders and plastic reinforced with glass fibers became commercial realities. These developments marked the beginning of the modern era of composite engineering materials. It was mentioned growing and using composite materials. Nevertheless, the emergence of a strict discipline and technology of composite materials is barely 20 years old.
3. There are two major reasons for the current interest in composite materials. The first is the demand for materials that will outperform the traditional monolithic materials. The second and more important in the long run, is that composites offer engineers the opportunity to design totally new materials, with the precise combination of properties needed for a specific task. Although new composites are usually more costly than conventional materials, they can be used more sparingly, because of their superior qualities.

Many young urban girls today smoke. While smoking is bad for your health at any time, it is particularly so during pregnancy and result in an underweight, small-size baby, and so smoking is best avoided during pregnancy. It is amazing how people persist in smoking despite so much warning regarding its hazards.
It is unwise to hold a lighted cigarette while holding the baby. Smoke may also irritate baby and make him cough and sneeze.

“My restaurant is called “Vienna”. Ten people work here. I am the owner. I go to the restaurant at four o’clock in the afternoon. The waiters arrive at half past four. They set the tables and tidy the kitchen. The chef, Pierre Rousseau, comes at five o’clock. He prepares the food for evening. The restaurant opens at six o’clock. Many people eat here because the food is good. The restaurant closes at one o’clock in the morning, and at half past one me, the chef and the waiters go home.”
