Research On Modification Theory And Technics Of Direct-Melting Glass Fiber Reinforced PA66

As the development of the science of oil, chemistry industry and material, the application of plastics becomes wider. It plays an important role in the daily lives. Plastics have many advantages, such as its light weight, good property of being molded, all kinds of colors, clean, resistance of abrasion, etc. Plastics have become the most important material in the new century. They have much good feature than the other materials, and can be used widely. In some fields, they even can take the place of the iron and steel. The composite is a new kind of material witch compounded by the macromolecule material and abio-nonmetal material. Because of the domino effect, it not only keeps the feature of the component, but also has some new advantages. It has a good development in the world.In this paper, the author studied the modification of direct-melting glass fiber reinforcing plastics, and this result has become the direct theory of the factory from witch the task came. By analyzing the experiment and its results, the effect of the glass fiber content to the stretch strength, the break elongation rate, the bent strength and the hardness degree are studied, and the best result...
