Composites processing methods

Figure 2.10 displays examples of market shares for the main composite processing methods. 

CNT-PMMA composite processing methods may broadly fall under the following four categories ... 

This entry will be divided into sections covering the classification of ceramics, a brief history of ceramics, raw materials for ceramics, properties and applications of ceramics, processing of ceramics, and a brief commentary on future trends. The field of ceramics is very broad and encompasses not only well-known, conventionally used materials and technology but also much newer compositions, processing methods, and applications. More detailed information on all of these sections is available in printed format and on the web.[ °- "l... 

After completion of the cure cycle, various operations still need to be carried out in order to obtain the final composite part. As these are common to most other composite processing methods, they are not discussed in detail here. However, it should be noted that each of these steps can add substantially to the overall component manufacturing cost, since they are time-consuming and might require expensive equipment. 

Prom the literature, a wide range of values have been reported for the percolation threshold and electrical conductivity of polymer/CNT composites, depending on the type of CNTs, nanotube functionalization, composite processing method and polymer employed [85,86]. Bauhofer and Kovacs analyzed the effects of experimental conditions, types of CNTs and polymers on the percolation threshold of CNT/polymer nanocomposites. They reported that the type of polymer and CNT dispersion play a more important role than the type and synthesis method of CNTs. Moreover, the electrical conductivity of nanocomposites with fully dispersed and exfoliated MWNTs in the matrix is 50 times higher than that of entangled ones [86].
