With the stricter safety and environmental standards and numerous restrictions, polymer tanks were gradually replaced by metal tanks to meet the new standards and higher safety, especially in accidents, weight reduction and fuel consumption, and reduction of CO2 and raw hydrocarbon pollution. It also leads to the possibility of increasing the volume of the tank. Especially, the research in the field of distribution of different nano fillers in polymers is very new, adding small amounts of it improves the properties and at the same time it leads to mechanical properties, permeability and weight reduction.
In this research, first of all, various polymers, Nano particles and Compatibilizers were introduced, and suitable materials were selected to improve permeability and mechanical properties, which were heavy polyethylene (HDPE) as the base matrix, PA12 and PET as filler polymers.Cloisite 30b has been used as Nano Filler and polyethylene bonded with Maleic An-hydride as Compatibilizer (antioxidant material).
The samples were transformed into the desired shapes by using the Internal Mixture device during a production stage and then by the hot press device to perform permeability and tensile tests. The main focus of this research is on the optimization of materials to reduce permeability of Nano Composite and increase mechanical properties.
The amount of passing flux in Polyamide is lower than that of polyethylene Terephthalate, and with increasing percentage of polymer and Nanoparticles, the passing flux increases. Also, the optimal amount of passing flux obtained is equal to 6.32, which has decreased by 57% compared to the normal state of the tank.
If we use polyethylene terephthalate instead of polyamide, the strength value increases by 15%, and with the increase of polymer percentage, the strength value decreases.
If we use polyethylene terephthalate instead of polyamide, the modulus value increases by 20%, but when we use a polymer in the range of 16-25% by weight, the same modulus value is obtained for both cases.
If we use the polymer in the same weight percentage, the amount of cost in the presence of polyethylene Terephthalate is reduced by 56% compared to Polyamide. On the other hand, the amount of cost increases significantly with the increase of polymer percentage in the tank in the presence of Polyamide, but it does not change much in the presence of polyethylene Terephthalate. Also, the optimal amount of cost obtained is equal to 7.11, which has decreased by 89% compared to the normal state of the tank.
