Article's abstract:

The effect of alumina and tough nylon 66 on microparticles’ presence the mechanical and thermal properties of epoxy adhesives is assessed here. In order to distribute the adhesive formulation components, in a uniform manner a mechanical stirrer is applied. The effect a combined percentage of nylon66 at (20, 30, 40 pph) and alumina micro-particles 20 μ (50,60,70 pph) selected based on Taguchi experimental design method on the mechanical and thermal properties of the adhesives is assessed. The tensile test results reveal that the sample containing 20 pph nylon 66 and 70 pph alumina micro particles has the highest Young’s modulus and tensile strength compared to other examples designed in Taguchi Table and Sample containing 30 pph nylon66 and 50 pph alumina micro particles has the highest degree of toughness compared to other specimens. The results of TGA reveal that the sample with the highest mechanical properties has a degradation startup temperature and more residual coal than pure epoxy. All this is due to the presence of nylon 66 that contains active hydrogen which in turn can increase cross-linking and degree of networking high and ultimately a higher thermal stability than the epoxy matrix. The results obtained from the FTIR test indicate that amide groups of nylon 66 are capable of interaction with epoxy rings.
