Plastics Engineering, Fourth Edition, presents basic essentials on the properties and processing behaviour of plastics and composites. The book gives engineers and technologists a sound understanding of basic principles without the introduction of unduly complex levels of mathematics or chemistry. Early chapters discuss the types of plastics currently available and describe how designers select a plastic for a particular application. Later chapters guide the reader through the mechanical behaviour of materials, along with a detailed analysis of their major processing techniques and principles. All techniques are illustrated with numerous worked examples within each chapter, with further problems provided at the end. This updated edition has been thoroughly revised to reflect major changes in plastic materials and their processing techniques that have occurred since the previous edition. The plastics and processing techniques addressed within the book have been comprehensively updated to reflect current materials and technologies, with new worked examples and problems also included.
Plastics are a wide range of synthetic or semi-synthetic materials that use polymers as a main ingredient. Their plasticity makes it possible for plastics to be moulded , extruded or pressed into solid objects of various shapes. This adaptability, plus a wide range of other properties, such as being light weight, durable flexible, and inexpensive to produce, has led to its widespread use. Plastics typically are made through human industrial systems. Most modern plastics are derived from fossil fuel based petrochemicals like natural gas or petroleum ; however, recent industrial methods use variants made from renewable materials, such as corn or cotton derivatives. In developed economies, about a third of plastic is used in packaging and roughly the same in buildings in applications such as piping , plumbing or vinyl siding. Worldwide, about 50 kg of plastic is produced annually per person, with production doubling every ten years.
Polymers abound in nature. Cellulose, the material that makes up the cell walls of plants, is a very common natural polymer. Over the last century and a half humans have learned how to make synthetic polymers, sometimes using natural substances like cellulose, but more often using the plentiful carbon atoms provided by petroleum and other fossil fuels. Synthetic polymers are made up of long chains of atoms, arranged in repeating units, often much longer than those found in nature. It is the length of these chains, and the patterns in which they are arrayed, that make polymers strong, lightweight, and flexible.
Thus, these plastics can not be successfully melted without damaging the molecular structure and the material changing color. This curing process forms an irreversible chemical bond.

Танкадо посмотрел на женщину, поднеся исковерканные пальцы прямо к ее лицу, как бы умоляя понять. Кольцо снова блеснуло на солнце. Женщина отвернулась.
Но я уезжаю сегодня вечером. Пожалуй, я все же оставлю ей записку. - И он положил конверт на стойку. Консьерж взглянул на конверт и что-то грустно пробормотал себе под нос. Еще один любитель молоденьких девочек, - подумал .
Веки припухли, глаза красные, левая рука у локтя - вся в кровоподтеках с синеватым отливом. Господи Иисусе, - подумал. - Наркотики внутривенно. Кто бы мог подумать. - Проваливай! - крикнула. - Вон.
Джабба покачал головой и бросил взгляд на Сьюзан, которая по-прежнему была где-то далеко, потом посмотрел в глаза директору. - Сэр, как вы знаете, всякий, кто хочет проникнуть в банк данных извне, должен пройти несколько уровней защиты. Фонтейн кивнул.
