better overall properties than the starting constituents. At a microscopic level, the constituent materials remain distinct within the finished structure. “Traditional” Composites Wood is a natural composite of cellulose fibers in a lignin matrix. Engineered wood is wood fibers, strands or veneers bound using adhesives.

By choosing an appropriate combination of matrix and reinforcement material, a new material can be made that exactly meets the requirements of a particular application. Composites also provide design flexibility because many of them can be moulded into complex shapes. The downside is often the

fibres that are embedded in a matrix [1], [2]. A composite is unlike an alloy because in an alloy, the other components have been produced by naturally occurring changes. There is a diversity of types of composites currently available, since “it is possible to design materials with property combinations that are better than those found in the metal alloys, ceramics and polymeric materials” [3]. The main ones focused on in this essay are polymeric matrices, metal matrix composites and ceramic composites

LEU Additive manufacturing: technology, applications and research needs © Higher Education Press and Springer-Verlag Berlin Heidelberg 2013 Abstract Additive manufacturing (AM) technology has been researched and developed for more than 20 years. Rather than removing materials, AM processes make three-dimensional parts directly from CAD models by adding materials layer by layer, offering

BCG Matrix Model BCG Matrix Model The BCG matrix or also called BCG model relates to marketing. The BCG model is a well-known portfolio management tool used in product life cycle theory. BCG matrix is often used to prioritize which products within company product mix get more funding and attention. The BCG matrix model is a portfolio planning model developed by Bruce Henderson of the Boston Consulting Group in the early 1970's. The BCG model is based on classification of products (and implicitly

The Boston Consulting Group (BCG) Matrix Autonomous divisions (or profit centers) of an organization make up what is called a business portfolio. When a firm's divisions compete in different industries, a separate strategy often must be developed for each business. The Boston Consulting Group (BCG) Matrix and the Internal-External (IE) Matrix are designed specifically to enhance a multidivisional firm's efforts to formulate strategies. The BCG Matrix graphically portrays differences
