A platform for research: civil engineering, architecture and urbanism
Plastics are a relatively new class of materials invented during the past century, and are now considered as engineering materials. This chapter presents the synergy and differences between materials science and engineering. It shows the mechanical engineering‐based paradigm for plastics engineering. Plastics are polymeric materials that can be classified into two broad categories: Thermoplastics and thermosets. In contrast to thermoplastics that have very high melt viscosities, thermosets can more easily fill small pores and wet out fibers because of their low initial viscosities. In using plastics, the four activities of materials characterization, part design, part fabrication, and assembly are interdependent and far more strongly coupled than in the use of metals. During the conceptual design phase, initial part shapes are chosen to satisfy functional requirements. This choice requires an understanding of the mechanical properties of the materials under consideration and the characteristics of the part shaping methods available.
