Abstract

The invention discloses a new type of automobile sound insulation foam reinforcement material, which relates to the field of automobile technology, in particular to a novel automobile sound insulation foam reinforcement material, comprising a first plate and a second foam sheet, the first plate A first foam sheet is installed below, and a second sheet is installed below the first foam sheet, a third sheet is installed below the second foam sheet, and the second foam The sheet is located below the second sheet. The invention provides a sound-insulating foam reinforcement material, which forms a mixed structure with the first plate, the second plate and the third plate, which not only increases the structural rigidity, reduces the structural weight, but also plays the role of sound insulation The effect of noise reduction, and the raw materials are relatively cheap, mainly chopped carbon fiber is mainly mixed with the foam matrix. Large-scale application can also effectively recycle carbon fiber waste. This new type of automobile sound insulation foam reinforcement material can effectively improve The resulting stiffness.

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...
