Abstract

Microwave processing has been investigated as an alternative to the conventional processing of polymers and polymer matrix composites. Different studies have demonstrated its viability and advantages, but various aspects related to its industrial applicability are still being investigated.

Two aspects related to the microwave curing of glass fiber/vinyl ester-vinyl toluene composites have been studied. A qualitative evaluation was done to determine the reproducibility of heating patterns of these laminates in different modes of a microwave resonant cavity. The samples were prepared to similar physical and chemical specifications and heated in different single modes of the cavity.

Another evaluation was done to compare the mechanical properties of microwave and thermally cured laminates subjected to flexural load. The samples were processed using similar cure cycles. The microwave samples were cured using a mode-switching technique and the thermal samples were cured in a temperature controlled oven. The void fractions of the samples were evaluated to develop pre-consolidation conditions that yield samples with low void fraction. Results of these two evaluations are discussed.
