Abstract

Nylon is made of repeating units linked by peptide bonds. Commercially, nylon\npolymer is made by reacting monomers which are either lactams, acid/amines or\nstoichiometric mixtures of diamines (-NH2) and diacids (-COOH).. In this paper a anew\ncomposite of Nylon is prepared. Directly a standard specimen is prepared by Injection\nmoulding. By adding wollastonite filler aiming in reduction of the elongation of Nylon.\nWollastonite is an industrial mineral comprised chemically of calcium, silicon and oxygen.\nIts molecular formula is CaSiO3 and its theoretical composition consists of 48.28% CaO\nand 51.72% SiO2.\nObjective: The objective of the work is to reduce elongation of the nylon . Compounds is to\nbe added to Nylon polymers to design composite materials with improved properties and to\nlower the overall production cost. In this investigation, the influence of adding inorganic\nmineral fillers on the mechanical properties of nylon is to be investigated.\nMethodology/approach: One or combination of more than one filler with different\npercentage by weight were added to nylon. Wollastonite with weight percentage varying\nbetween 5, 10 and 15 wt.% were added to nylon. Samples of the composites were prepared\nby injection molding process. Uniaxial tensile tests were carried out.\nResults: From testing elongation % of all sample were fined, test value shows for sample-1\ni.e for 5% CaSiO3 elongation is 8%, for sample-2 4% and for sample-3 5.5%. The results\nshowed that the elongation of nylon composite decrease with the filler addition, while the\nweight ratio 5% and 10% but it is increasing when it is 15% then 10% addition. The\nmaximum improvement is recorded with the addition of 10 wt.% filler ratio.\nResearch limitations/implications: A correlation has been developed to predict the changes of\nproperties with the addition of different ratio of filler material on the change in elongation.
