Abstract
The influence of processing conditions on the resulting mechanical pro perties of glass/PET composites has been investigated. First, we studi ed the anisothermal crystallization of PET with and without glass fibr es, considering both thermodynamic and kinetic aspects. The main varia bles considered were temperature of treatment in the molten state (T(i )) and cooling rate (nu). Second, according to the results of the firs t part unidirectional composites were compression moulded. Short-term (dynamic and static) shear tests and long-term flexural fatigue tests were performed to characterize the effects of moulding conditions. Thi s study demonstrates that the thermochemical history during the compos ite processing significantly influences the short- and long-term mecha nical properties of the composite especially in the presence of shear stresses.
