At present, Chinese researchers have considerable knowledge and experience in the synthesis of aluminum borate whiskers, reinforcing and toughening composites, and industrialization. Before long, aluminum borate whiskers will be used widely in reinforced metal matrixes (aluminum base, magnesium base), ceramic matrix, plastic, glass, fiber, and coatings. ...

Insulation fiberglass is glass wool used for thermal and acoustic insulation of homes, commercial buildings, industrial equipment, and automobiles. It has a sodium aluminoborosilicate-based composition, often with additional modifiers, such as calcium, magnesium, and potassium, which vary by... 

Most structural PMCs consist of a relatively soft matrix, such as a thermosetting plastic of polyester, phenolic, or epoxy, sometimes referred to as resin-matrix composites. Some typical polymers used as matrices in PMCs are listed in Table 1.28. The list of metals used in MMCs is much shorter. Aluminum, magnesium, titanium, and iron- and nickel-based alloys are the most common (see Table 1.29). These metals are typically utilized due to their combination of low density and good mechanical properties. Matrix materials for CMCs generally fall into fonr categories glass ceramics like lithium aluminosilicate oxide ceramics like aluminnm oxide (alnmina) and mullite nitride ceramics such as silicon nitride and carbide ceramics such as silicon carbide.
