Fibers may be in the form of "whiskers" of substances such as silicon carbide or aluminum oxide that are grown as single crystals and that therefore have fewer defects than the same substances in a bulk ceramic (Figure 5.6~. QQT for plenary. For example, a molecule of poly(ethene) is made by joining thousands of ethene molecules together. Different materials have different properties. This is a useful property because it means that plastic bottles will not react with their contents. Updated 3/11/17 with a new 6 page PDF of the research resources.
