Abstract
The aim of this work is to study the replacement of the support of the engine mounts from aluminum to commercial polyamide composite (PA 6.6) reinforced with 30, 35 and 50 % of fiberglass. The purpose of this replacement is to reduce the weight of the component. Flexion and fatigue tests were performed at 120 °C utilizing the Staircase Method. The results have shown the excellent adherence of polyamide in fiberglass. The polyamide composite with 50 % fiberglass presented the lowest deflection. The comparison of the tension distribution utilizing the Finite Element Method between the supports of the bearing engine made of polyamide with fiberglass and Al alloy have shown almost the same results. However, the polyamide composite presented higher values of deflection. Finally, due to the weight reduction of 32 %, it was possible to confirm that the polyamide composite is viable to change the Al alloys in automotive engine bearings.
