Abstract

The Study of the Effect of Aluminum powder on the bending resistance properties and fire retardant for unsaturated polyester, which is manufactured in Turkey, a function of the percentages of Aluminum powder (0.5%, 0.8%, 1%, 1.5%, 2%, 2.5%), a particular size (150 µm), were investigated through several variables, such as, bending resistance and the flame resistance. In addition, the samples of the base material (unsaturated polyester) were measured in a pure and when the aluminum powder was added by optical microscopy. Absorption spectrometer measurements were taken in the infrared (FTIR) area of the pure and the polymer with the weight ratios of the fillers. The results lead to that the strength at bending resistance is (140 Mpa) at the percentage (0.8%). The obtained results appeared that, when the added Aluminum powder to reduce the spaces between the polymer chains, which reflects the high ability of the polymer against the applied stress, the degree of homogeneity is high between polymer and additives. Also, the results indicated a lowered percentage in bending resistance at the percentage (2.5%) is (84.3Mpa), and observe that the average time of burning starts strong impact when (0.5%) as increasing to (168 Sec) and then begins to decline behavior when increasing proportions weight and then increasing behavior when increasing proportions when (2.5%) as increasing to(195 Sec). The results also indicated that the percentage for the time of burning ranged between negative values at the low weight ratios of the added (1.5% - 0.5%) and positive values at the high weight ratios (2% -2.5%).
