MATERIALS SELECTION: November 2011
http://materialselection.blogspot.com/2011_11_01_archive.html
Comparative Properties of Composite Materials. For applications in which both mechanical properties and low weight are important,. The carbon fibers represented in Fig. 2 are made from several types of precursor materials:. Polyacrylonitrile (PAN), petroleum pitch, and coal tar pitch. Characteristics of the. Two types of pitch-based fibers tend to be similar but very different from those made from. PAN Several types of carbon fibers are represented: standard-modulus (SM) PAN, ultrahighstrength. It is not...

MATERIALS SELECTION: Function, material, shape and process
http://materialselection.blogspot.com/2011/03/function-material-shape-and-process.html
Function, material, shape and process. And the greater the interactions. It is like making wine: to make cooking wine, almost any grape and fermentation process will do; to make champagne, both grape and process must be tightly constrained. The interaction between function, material, shape and process lies at the heart of the material selection process. But first: a case study to illustrate the design process.

MATERIALS SELECTION: Manufacturing Considerations
http://materialselection.blogspot.com/2011/12/manufacturing-considerations.html
Composites also offer a number of significant manufacturing advantages over monolithic metals and ceramics. For example, fiber-reinforced polymers and ceramics can be fabricated in large, complex shapes that would be difficult or impossible to make with other materials.

PLASTICS MANUFACTURING: September 2011
http://plasticsmanufactur.blogspot.com/2011_09_01_archive.html
Monday, September 19, 2011. Syndiotactic polystyrene is a semicrystalline polymer and is produced via metallocenecatalyzed polymerization of styrene.21 By comparison to general-purpose, amorphous polystyrene (PS, HIPS), SPS has tereoregularity in its structure, which facilitates crystallization. In SPS the phenyl groups alternate above and below the polymer chain. Hence SPS has a high crystalline melt point and good chemical resistance. Edward N. Peters. Selkirk, New York. Edited by Myer Kutz. Examples o...

PLASTICS MANUFACTURING: Chemical/Solvent Resistance
http://plasticsmanufactur.blogspot.com/2011/03/chemicalsolvent-resistance.html
Friday, March 11, 2011. When an application requires exposure to or immersion in chemicals or other harsh environments, it is of prime importance to use prototypes of suitable stressed material for testing under actual operating conditions.

PLASTICS MANUFACTURING: Styrene/Acrylonitrile (SAN) Copolymer
http://plasticsmanufactur.blogspot.com/2011/12/styreneacrylonitrile-san-copolymer.html
Saturday, December 3, 2011. Increase SAN’s physical properties but will make melt processing more difficult and will decrease the transparency. In general, the AN level in SAN does not exceed 30% for molding applications. Typical properties appear in Table 7. Uses. SAN is utilized in typical PS-type applications where a slight increase in heat deflection temperature and/or chemical resistance is needed. Such applications include appliances.

PLASTICS MANUFACTURING: Polymeric Materials
http://plasticsmanufactur.blogspot.com/2011/09/polymeric-materials.html
Saturday, September 10, 2011. Synthetic large molecules are made by joining together thousands of small. Molecular units known as monomers. The process of joining the molecules. Is called polymerisation and the number of these units in the long molecule. Is known as the degree of polymerisation. The names of many polymers. Coupling agents are added to improve the bonding of the plastic to inorganic filler materials, such as glass fibres. A variety of silanes and titanates are used for this purpose. Lubri...
