Abstract

The invention discloses a new automobile sound insulation foaming reinforcing material, and relates to the technical field of automobiles. The new automobile sound insulation foaming reinforcing material comprises a first plate and a second foaming body sheet, a first foaming body sheet is arranged below the first plate, a second plate is arranged below the first foaming body sheet, a third plateis arranged below the second foaming body sheet, and the second foaming body sheet is positioned below the second plate. According to the sound insulation foaming reinforcing material, the material, the first plate, the second plate and the third plate form a mixed structure, so that the aims of increasing the structural rigidity and reducing the structural weight are achieved, moreover, the effects of sound insulation and noise reduction are achieved, the raw materials are relatively cheap and mainly take mainly short-cut carbon fibers as the main part and are mixed with a foaming matrix, a large-range application can also play the effect of effectively recycling carbon fiber waste materials, and the new automobile sound insulation foaming reinforcing material can effectively improve thestructural rigidity.

Description

technical field [0001] The invention relates to the technical field of automobiles, in particular to a novel foaming reinforcement material for sound insulation of automobiles. Background technique [0002] In the traditional metal body structure, the method of improving the rigidity is mainly realized by selecting high-strength steel or changing the cavity structure. The structure weight of the high-strength steel design method is heavy and the price is high, which cannot meet the requirements of good cost performance; the improvement of sound insulation effect is in the cavity. Adding a single foaming material to fill in can not play a role in enhancing the rigidity. [0003] The existing traditional metal body structure has complex assembly levels, heavy weight, poor sound insulation performance, and low rigidity and strength. Contents of the invention [0004] Aiming at the deficiencies of the prior art, the present invention provides a new type of automobile sound in...
