Follow me, don’t get lost when applying for the college entrance examination. Hello everyone! Welcome to Teacher Su’s professional class. Today we are going to talk about the ⑧ major in materials category--Composite Materials and Engineering. Its professional code is 080408. We still explain from five aspects: what we are, what we are learning, where we are going, what we will do in the future, and what our direction for the postgraduate entrance examination will be.
With the development of social economy, it is difficult for simple materials to make breakthroughs in quantity. It has become history to discover new materials on a large scale and use them for human use. Material scarcity forces people to combine two or more materials of different properties, and the materials formed by this combination are composite materials. The discipline that studies the properties of various materials and composes them according to new performance requirements is composite materials and engineering. This major covers knowledge in many fields such as physics, chemistry, materials science, , mechanics, etc., and is a new technical discipline with multiple disciplines intersected. In terms of performance, composite materials can not only avoid the disadvantages of their synthetic materials, but also have the advantages of synthetic materials. For example, the composite material of carbon fiber and epoxy resin has excellent chemical stability and heat resistance, fatigue resistance, sound absorption, electrical insulation and other properties. The burn-resistant materials formed by carbon fiber reinforced carbon, graphite fiber reinforced carbon or fossil fiber reinforced graphite composite have been used in spacecraft, rocket missile and atomic energy reactor .
composite materials have a wide range of applications and have broad development prospects. Its R&D level and industrialization scale have become an important indicator to measure a country's economic development, scientific and technological progress and national defense strength. With the rapid development of domestic pillar industries and high-tech industries, such as machinery manufacturing industry , electronic information manufacturing industry, automobile industry, construction industry and other industries, the demand for this professional talents is increasing. Studying this major requires good chemistry and physics grades, strong hands-on ability and math ability. Girls should apply carefully.
The main courses in composite materials and engineering include composite materials mechanics , electrical and electronics, composite material structural design, composite material principles, introduction to materials science, composite material technology and equipment, polymer materials and processing, nanocomposite materials, etc.
Representative colleges of this major include Harbin Institute of Technology , Wuhan Institute of Technology , East China Institute of Technology , Northwest Institute of Technology , Jiangsu University , Nanjing University of Technology , Qingdao University , Northeast University of Technology , Tianjin University of Technology , Inner Mongolia University of Science and Technology , etc.
Graduates of this major can engage in all work related to composite materials, and can engage in the development, material modification, processing, synthesis and other aspects of synthetic resin , rubber, chemical fiber, coatings, adhesives, electrical insulating material , high-performance materials, functional polymer material in chemical industry, light industry electromechanical, building materials, transportation, construction and other industries. It can be said that from national defense to daily necessities, it involves composite materials, so it is relatively easy to find employment in this major. But its employment varies by gender. Many units clearly require male gender to be hired when recruiting. Basically, boys have the opportunity to be hired as long as they participate in the interview, and girls are subject to many restrictions and employment is relatively difficult. In addition, the starting salary in the materials industry is relatively low, and the working environment is poor in the early stages of employment. With the accumulation of experience and the improvement of ability, the working environment and salary will improve.
Graduates of composite materials and engineering majors mainly apply for master's degree students in materials science, materials science and engineering, materials engineering, materials processing engineering, material physics and chemistry , polymer chemistry and physics, etc. The research directions of the master's major in materials science mainly include the preparation and toughening theory of high-performance composite , material friction and wear and surface modification, the preparation and processing of high-purity mineral materials, biological materials, etc.
