The Impact

The goal of this research is to investigate the impact of the three parameters on the cure of the unsaturated polyester resin. The obtained values show the influence of each parameter on the cure and hence enables to establish a time-range with regard of the percentage of the components for a good management of the curing process.

Sisal Fibers

Biobased products have been widely used to prevent damage to the environment. In this context, the use of composites reinforced with natural fibers, replacing synthetics ones, has motivated several researches in last years. The objective of the present work was to characterize composites prepared with unsaturated polyester resin and untreated sisal fibers by tensile and flexural tests. The untreated sisal fibers reinforcement was investigated using 25 g and 50 g masses. The fibers were randomly arranged into the resin to mold composite boards, using the compression molding technique without heating, in a curing process at 25°C for 48 hours. The results indicated that composite with 50 g presented better tensile strength (49%), flexural strength (71%) and flexural modulus (137%). The increase of fibers content improved the mechanical behavior of the composite. In addition, the use of natural fibers replacing a portion of petroleum-based resin can increase the sustainable concept of the products and reduce manufacturing costs, because it can be used less resin.

Recycled Polyethylene

A technique has been developed for producing an unsaturated polyester resin by transesterifying the product of glycolysis of secondary polyethylene terephthalate using maleic and phthalic anhydride. The curing process was studied, it was found that the unsaturated polyester resin was cured by the action of oligoether acrylate (TGM-3), peroxide compound (methyl ethyl ketone peroxide) and accelerator (manganese hydroxide divalent, acetylacetone, cobalt stearate). The physic-mechanical characteristics of polymeric materials based on unsaturated polyester resin, the analysis of which indicates a high thermal stability, have been studied.
