Viscoelastic properties of polymeric metal composites

Kompoziti so materiali, sestavljeni iz dveh ali več materialov, ki so si po kemijski sestavi različni. Polimerno kovinske kompozite sestavljata polimerna matrica in polnilo. V predstavljeni nalogi so bili za polnilo izbrani kovinski delci aluminija, titana in nerjavnega jekla. Vsi delci so bili dodani v obliki prahu. V okviru zaključne naloge smo z rotacijskim reometrom MCR 302 (Anton Paar) proučili vpliv koncentracije izbranih kovinskih delcev na viskoelastične lastnosti kompozita, hkrati pa smo primerjali še vpliv treh vrst materialov. Izvedli smo amplitudne in oscilacijski teste pri temperaturi 175°C. Ugotovili smo, da na viskoelastične lastnosti polimerno-kovinskih kompozitov vplivata koncentracija delcev in material, iz katerega so dodani delci.Composites are a combination of two or more materials with different chemical structure. The two key components in metal polymer composites are matrix and a filler. In the present study fillers were made of aluminum, titanum and stainless steel particles which were added as a powder. For the purpose of this study we used rotational rheometer MCR 302 (Anton Paar) which allowed an investigation of the effect of metal particles concentration on the properties of composites. At the same time we compared the effect of three dissimilar types of the filler. For the investigation oscillatory amplitude and frequency tests were performed at the temperature of 175°C. At the end of the study we can conclud that the particle concentration and material have a great impact on viscoelastic properties of metal polymer composites
