This type of coatings is also
characterized with a large number of grain boundaries with a crystalline/amorphous
transition across grain–matrix interfaces, restricting the rise and development of cracks.
Such mechanism explains the resistance to fragile cracking of nanocomposite coatings
(Veprek, 1997; Veprek, 1998; Rafaja et al., 2006).
Fiber composite technology is based on taking advantage of the high strength and
high stiffness of fibers, which are combined with matrix materials of similar/
dissimilar natures in various ways, creating inevitable interfaces. In fiber composites,
both the fiber and the matrix retain their original physical and chemical identities,
yet together they produce a combination of mechanical properties that cannot be
achieved with either of the constituents acting alone, due to the presence of an
interface between these two constituents.
The HD44780U dot-matrix liquid crystal display controller and driver LSI displays alphanumerics,Japanese kana characters, and symbols. It can be configured to drive a dot-matrix liquid crystal displayunder the control of a 4- or 8-bit microprocessor. Since all the functions such as display RAM, charactergenerator, and liquid crystal driver, required for driving a dot-matrix liquid crystal display are internally provided on one chip, a minimal system can be interfaced with this controller/driver.
