Abstract: A vehicular powertrain mount assembly comprising two metal bracket members and a volume of a resilient elastomeric material sandwiched between and adhesively bonded to the two brackets. An epoxy adhesive is used in bonding the metal to the elastomer producing a bond having a minimum tensile rupture strength of 3,000 Newtons when tested by ASTM D-429.

Abstract: A composite leaf spring for a motor vehicle has an elongated body of layers of epoxy coated fibers extending in the longitudinal direction of the spring. The composite fiber/adhesive body is formed and cured to provide sufficient strength and flexibility to suspend the vehicle. A synthetic fiber pad is fixed adjacent the end of the spring for engagement with the spring hanger of the suspension system to resist wear of the body at the interface with the hanger. In the preferred embodiment, the pad is a woven fabric of aramid fibers at least some of which extend substantially normal to the wear interface. A specific double plane weave fabric including a warp/fill fiber ratio of approximately 7:1 provides superior results. Epoxy resin is preferred for the adhesive both for the body of the spring and for pre-impregnation of the pad. In the related method, the pre-impregnated pad is applied to the mold contoured to correspond to the shape of the spring and elongated fibers are layered in the mold over the pad.
