Talking about the impact of plastic composites on automobile lightweight

Plastics and composites can show a wide range of mechanical properties, and the changes between most components will be unavoidable in the production process, so it will cause some deviations, and then have manufacturing defects. These manufacturing defects can be attributed to many factors, such as fluctuating heat treatment temperature, molding defects, or inconsistent quality of plastic materials

however, how to ensure the quality of raw plastics or the integrity of plastics requires a specific set of evaluation and plastic inspection methods. The accuracy of data for manufacturing or evaluating a plastic product can be determined through the inspection of the chemical and physical properties of the original plastic resin or fiber. Raw plastics usually form vitality after a series of tests and screening, and the quality inspection after production usually depends on various testing methods

plastic composite materials for automobile lightweight

raw material inspection

the quality inspection of most plastic raw materials involves resin or fiber formation. Resin, the main indicators include viscosity, moisture content, and color, while continuous fibers often check their tensile strength. Infrared and nuclear magnetic resonance spectroscopy are usually used to identify basic chemical structures and pollution levels. Other standard methods include chemical analysis, revealing the main acid or epoxy groups in a plastic compound, and liquid or gel chromatography to determine, but excess capacity and sluggish consumption force end consumer goods manufacturers not to reduce prices and promote the average molecular weight and molecular weight distribution in resin molecules

the detection accuracy of chromatographic technology is particularly high, because the molecular weight and its distribution will affect the viscosity and mechanical properties of plastic materials. In poly these are related to the experimental potency of esters, low molecular weight generally yields higher viscosity, resulting in a slower thickening rate. This can make the plastic more difficult to handle or extremely long thickening to an appropriate degree. The level of water will also affect the thickening rate

ultrasonic inspection

ultrasonic inspection uses high-frequency sound waves to track internal defects in a plastic material. Electric transducers generate sound waves, which are then applied to plastics, such as water, through a separate medium. Seismic waves pass through the material and their energy levels, transforming according to the defects they encounter. The receiving transducer converts it into sound waves and reflects it into electrical signals, which are displayed on the screen. The results can then be compared with the predetermined design features and identify any internal defects

radiographic examination

photography involves emitting a radiation beam through a plastic part, then recording and measuring its power when exiting through the other party. The material helps to determine the difference between the initial strength and strength of the beam after the defect inside the object. The standard method uses X-rays, which are then recorded on photographic film images, while γ Rays are more effective on thicker materials because they provide a higher degree of penetration. Defects in plastic appear in the hue or spot of the film image. Photography is commonly used to detect the following defects

like ultrasonic technology, acoustic emission detection method uses sound waves to determine the defects of materials. However, instead of sending sound wave reflection, acoustics relies on the emission of elastic stress released by sound from the micro damage area. In reinforced plastic composites, a small degree of stress will lead to the emission of the damaged parts, so that acoustic emission detection of the defect location of the molded product map

plastic compliance materials are widely used in the field of "automobile lightweight"

plastic composites are one of the common non-metallic materials in automobiles, and the amount of plastic used in the automotive industry has accounted for 15% of the total plastic output. The application prospect of plastic composites in the automotive industry is also promising

with the continuous development of science and technology, people's requirements for quality of life have once again become the mainstream of the market, and their demand for material life is increasing. In order to facilitate travel, buying private cars has become the choice of more and more consumers. Private cars have become increasingly popular. It can be predicted that economic growth has greatly promoted the process of people buying private cars

however, on the basis of limited existing funds, performance is still one of the hot spots that consumers pay attention to. Among them, energy conservation and vehicle safety are nothing more than the most enthusiastic concerns of most consumers, and the requirements are getting higher and higher. For this, automobile manufacturers have to strive to find new car making materials to meet the needs of the public. In June this year, a huge wave of "automobile lightweight" rushed to China. This news makes my heart beat

in recent years, there are more and more kinds of plastic composite materials, and the composite materials used in the fuselage account for 64.6% of the whole. The application field is becoming wider and wider. The development and application of lightweight materials such as plastic composite materials play an important role in the lightweight process of automobiles. In the process of automobile lightweight, China's plastic composite industry is undergoing the transformation from introduction to innovation, from follow to guidance, and from closed to open. The independent development of new materials such as plastic composites and the innovation of processing technology are further accelerated. The improvement of global safety, environmental protection and energy saving standards puts forward new requirements for the testing technology of plastic composites

it is reported that for China, the application of plastic composites in the automotive industry is still in its infancy. At present, the application of non-metallic materials such as plastic composites in domestic cars is not as good as that of imported cars

it can be predicted that with the acceleration of automobile lightweight process, plastic composites will be more widely used in automobiles. In fact, replacing metal parts with plastic composites can not only reduce the weight of cars, but also reduce friction and energy consumption. In short, the application of plastic composites in automobiles has brought unprecedented benefits, including reducing automobile emissions and improving fuel efficiency. In short, the author believes that greatly improving safety is one of the greatest benefits
