A composite structure comprises a cover plate and a plate-like fiber layer, one side of the plate-like fiber layer being fastened to one side of the cover plate with a solder at contact points of fibers of the plate-like fiber layer and the cover plate. Contacting fibers of the plate-like fiber layer are connected to each other with the solder in the plate-like fiber layer. A vehicle having a composite structure and a method of manufacturing a composite structure are furthermore disclosed.

The disclosed inventive concept provides a further achievement in efforts to produce a tunable exhaust sound for a vehicle. The system provides a tunable exhaust system including a tunable resonator and a pair of tunable mufflers. The tunable resonator includes a housing including first, second and third expansion chambers. A pair of bank-by-bank exhaust conduits extends through the housing. At least one of the conduits includes a band of peripheral perforations within the first expansion chamber. The band is formed at an angle relative to the long axis of the conduit on which it is formed. The mufflers include inlet and outlet pipes. At least one of the outlet pipes includes a variable exhaust gas flow assembly. The variable exhaust gas flow assembly includes a vane shaft, an exhaust gas regulating vane attached to the vane shaft, and a vane actuator for regulating the position of the vane shaft.

A self-cleaning duct assembly. The self-cleaning duct assembly includes a hollow member having an inner surface, the inner surface defining a central axis and a flow passage for directing a fluid flow along the central axis. The self-cleaning duct assembly also includes a resilient member including a plurality of arcuate segments disposed along the central axis, each of the arcuate segments spaced from the inner surface. The arcuate segments intermittently contact the inner surface as the resilient member is induced to move within the hollow member.

A vehicle exhaust system includes a vehicle body structure, an exhaust system, a rear bumper assembly, an exhaust finisher and a boot. The exhaust assembly is supported to an underside of the vehicle body structure. The rear bumper assembly is also supported to the vehicle body structure. The exhaust finisher is non-movably attached to one of the vehicle body structure and the rear bumper assembly. The exhaust finisher extends at least part way through an opening of the rear bumper assembly. The boot has a first end, a second end, and a flexible portion. The first end is attached to a rear end of the exhaust assembly. The second end is attached to a forward end of the exhaust finisher and the flexible portion extends from the trout end to the second end. The flexible portion is elastically deformable in response to thermal expansion and contraction of the exhaust assembly.

The present invention relates to a ferritic stainless steel according to the present invention, containing, in mass %: 0.001%C0.020%, 0.05%Si0.50%, 0.1%Mn1.0%, 15.0%Cr25.0%, Mo<0.50%, 0.50%W5.00%, and 0.01%Nb0.50%, with a balance being Fe and unavoidable impurities, having a content (coarse Laves phase ratio) of coarse Laves phase having a diameter of 0.50 m or more being 0.1% or less, and having an average grain size being 30 m or more and 200 m or less.

The present disclosure relates to a vehicle exhaust assembly (1) for an internal combustion engine. The vehicle exhaust assembly (1) comprises an exhaust system (3) and an exhaust mounting assembly (4) for mounting the exhaust system (3) to a vehicle (2). The exhaust system (3) comprises an inlet section (5) for connection to the internal combustion engine; an intermediate section (6) connected to the inlet section (5); an outlet section (7) for exhausting gases from the internal combustion engine; and one or more exhaust decoupler (8) for decoupling the intermediate section (6) from the inlet section (5). The exhaust mounting assembly (4) comprises one or more first isolator device (20-1, 20-2) for resiliently constraining movement of the intermediate section (6) of the exhaust system (3) in a longitudinal direction; and one or more second isolator device (20-3, 20-4) for resiliently constraining movement of the outlet section (7) of the vehicle (2) exhaust in a transverse direction. The present disclosure also relates to a vehicle (2) including a vehicle exhaust assembly (1).
