ABSTRACT
This chapter aims to cover the phenomenon of transcrystallinity in Single-Polymer Composites (SPCs) system. Polarized optical microscopy and a universal tensile test machine were used to investigate the influences of fiber introduction temperature on the resultant morphology of transcrystallinity (TC) or transcrystalline layers (TCL) and mechanical properties of SPCs. It is interesting to note that the optical nature of the TC layers changed at a function of crystallization temperature. Transcrystalline growth was observed as a function of temperature and as a function of the degree of undercooling in their research. The effect of TC has been widely debated by the research groups. However, it has been generally agreed that due to its anisotropy, the formation of a TCL has critical effects on performances of fiber/polymer interfaces. The researchers observed that the incidence of a TCL and its magnitudes in the composite was a function of many factors mainly type of fibers, matrix used, and processing conditions.
