Thermal Characterization of a Reinforced Elastomer

Abstract

The effect of the presence of fillers on the thermal properties of a high performance elastomer was investigated in this work. The characterization of the specific heat capacity (Cp), the specific heat flow and the glass transition temperature of a polyurea elastomer reinforced with two different classes of fillers, i.e. short glass fibers and alumina nanoparticles, was conducted by using a differential scanning calorimeter (DSC). We present and discuss the results of the experimental characterization carried out on the reinforced material. The results are compared to those obtained by testing the pure polymer.

Polymeric Composites Based on Polyurea Matrix Reinforced with Carbon Nanotubes

“…Polyurea is currently the most successful material used in industrial coatings. This is determined by many factors as: progress in the polyurea synthesis and application technology, high rate of curing at relatively low temperatures [2], high chemical resistance, moisture impermeability, excellent mechanical properties (high flexibility, tear, abrasion and tensile strength), low flammability and excellent durability [3]. Due to this properties, polyurea is superior to the polyurethanes.…”

“…The advantage of the polyurea use in the coating domain consist in the absence of any solvent or any volatile organic compound which allows the use of a suitable processing equipment by spraying the two components (the diisocyanate and the diamine). The spray process was developed in the 90s and nowadays constitutes the main technology for polyurea coatings [3][4][5].…”

“…Dynamic response of metal / polyurea composites was studied by numerical methods as well as experimental methods. * email: gheorghe_hubca@yahoo.com Several studies deal with the test of steel plate composites coated with a thin coating of polyurea [3,[9][10][11][12], as well as aluminum plates coated with polyurea [13][14][15]. To improve the polyurea properties, nanocomposites were obtained using MWCNT, nanoclays or POSS as nanofiller [16][17][18][19][20][21][22][23].…”
