Abstract

The invention discloses a carbon fiber composite material automobile exhaust pipe tailpipe and a manufacturing method thereof, belonging to the field of automobile exhaust pipe tailpipes. The automobile exhaust pipe tailpipe comprises: a first pipe with an air outlet connected in sequence, a bent connecting pipe, a second pipe with an air inlet and a composite metal flange. The first pipe, the bent connecting pipe, and the second pipe are pipes formed of a composite material including carbon fiber, and the middle portion of the first pipe has a boss formed of a composite material including carbon fiber. By arranging the connecting pipe connecting the first pipe and the second pipe into a bent shape, the installation space of the automobile exhaust pipe tail pipe can be reduced, and the installation is convenient. By setting the middle part of the first pipe as a boss of carbon fiber composite material, the heat insulation effect of the automobile exhaust pipe is improved, and the normal operation of the automobile parts around the first pipe can be guaranteed. The carbon fiber composite automobile exhaust pipe tail pipe has the characteristics of shock resistance, corrosion resistance, light weight, good heat insulation effect, small installation space and the like.

Description

technical field [0001] The invention relates to the field of automobile exhaust pipe tailpipes, in particular to a carbon fiber composite material automobile exhaust pipe tailpipe and a manufacturing method thereof. Background technique [0002] With the continuous development of my country's economy, automobiles have been widely popularized in life. The car mainly provides power through the power system to drive normally. Among them, the car exhaust system can discharge the exhaust gas generated by the car power system to maintain the normal operation of the car power system. The automobile exhaust system mainly includes an exhaust manifold connected in sequence, an automobile exhaust pipe, a catalytic converter, an exhaust temperature sensor, an automobile muffler, and an automobile exhaust pipe tailpipe. Automobile power system burns fuel to produce air with huge heat, part of the hot air drives the engine to operate, and the other part of exhaust gas will enter the exha...
