Designer materials

Since the discovery of living cationic systems, cationic polymerization has progressed to a new stage where the synthesis of designed materials is now possible. The rapid advances in this field will lead to useful new polymeric materials and processes that will greatiy increase the economic impact of cationic initiation. 

Integral-type pipe attachments in elevated temperature service are subjected to the same design, material, fabrication, and inspection requirements as the pipe to which they are attached. 

AH implantable medical devices ate complex in design, materials, and implementation procedures. The biocompatibiUty, biodurabiUty, and efficacy of medical devices are the subject of extensive research by biomaterials scientists, device manufacturers, and health care professionals. 

Temper. The system for designating material condition, whether the product form is strip, rod, or wine, is defined in ASTM Recommended Practice B601 (1). The ASTM system uses an alpha-numeric code for each of the standard temper designations. This system replaces the historical terminology of half hard, hard, spring, etc. Table 3 summarizes temper designations. 

The purpose of testing an electrical motor is to ensure its compliance with the norms of design, material inputs and manufacturing accuracy. It determines the mechanical soundness and electrical fitness of the machine for its electrical and mechanical performance. Such tests determine the following ...

The mechanical properties of plastics enable them to perform in a wide variety of end uses and environments, often at lower cost than other design materials such as metal or wood. This section reviews the static property tests. Chapter 5 provides more information on the meaning of these type data. 

Based on the detailed design select the probable product design, material, and process. 

Let it be known that one can say the tests are essential and all provide useful functions. However like design, material and process variables that exist, there are also testing variables. In order to apply them to a design, the designer should understand their meanings and purpose for existing. The result will be the proper use of tests. 

The problem of acquiring complete knowledge of candidate material grades should be resolved in cooperation with the raw material suppliers. It should be recognized that selection of the favorable materials is one of the basic elements in a successful product-configuration design, material selection, and conversion into a finished product (Appendix A PLASTICS DESIGN TOOLBOX).
