Problems solved by technology

3. The intake manifold needs to withstand pressure and vibration load for a long time
However, the ability of additives to improve the surface problems of products is limited, and the addition of too many low-molecular-weight substances will reduce the rigidity and aging resistance of the material. Differences, easy to fluctuate during extrusion and granulation, these many unstable factors make it difficult for the product to meet the requirements of safety and high stability
The adoption of special production techniques and equipment will lead to higher production costs

Description

technical field [0001] The invention belongs to the technical field of polymer materials, and in particular relates to a glass fiber reinforced PA66 automobile intake manifold material and a preparation method thereof. Background technique [0002] The intake manifold is the most important part of the intake system of the automobile engine. The intake system determines the intake efficiency of the engine and the uniformity of the inflation of each cylinder, which has a great impact on the performance of the whole machine. The intake manifold is fixed on the cylinder head of the engine and is a hollow product with complex shape. It bears the heat and vibrations transmitted by the combustion of fuel in the combustion chamber of the cylinder head. The working environment of the intake manifold is complicated, and mainly has the following characteristics: 1. There are often heat radiation, conduction, and convection in the working environment. It can be changed in the range of...
