dc.description.abstractThe continuous development of composites is essential to provide the adequacy of their properties to innumerable applications, either in medicine or in civil construction areas. Previous studies were concerned to a pre-polimerization of acrylic mixtures, in order to hinder the decantation of inorganic charges via irradiation. The success of the experiment, confirmed by MEV inspections, fostered the continuity of trials, by assessing too polyester resin and its combination with acrylics and inorganic loads, all of formulations being subjected to gamma radiation, within 3.0 to 15 kGy doses. Gel extractions tests indicated a trend for higher performance in terms of crosslinking, for samples containing inorganic charges. Within 7.5 to 15 kGy doses, samples containing polyester presented excellent results for gel extraction: 84.65 to 95.19%, when compared to samples comprising just acrylics. Samples comprising acrylics, irradiated at 3.0 kGy, failed when tested as per gel extraction, i.e., dissolved completely in acetone, solvent commonly used for the extraction. Furthermore, there will be required further assessments, for all combinations studied, besides investigating crosslinking agents, which showed a non-expected poor gel fraction results, when combined with acrylics. In addition, these crosslinking agents will be formulated with polyester resin, to complete the present study. Further evaluations will consider gamma radiation doses within a 3.0 – 7.5 kGy range.
