What are the types and types of composite materials?
Hello, I am the customer service representative of Kunshan Inko Printing Materials Co., Ltd., and I will be happy to answer your questions. Composite 5 is a mixture. It has played a great role in many fields and replaced many traditional materials. Composite materials are divided into metal and metal composite materials, non-metal and metal composite materials, and non-metal and non-metal composite materials according to their composition. According to their structural characteristics, they are divided into: ① Fiber reinforced composite materials. It is composed of various fiber reinforcements placed in the matrix material. Such as fiber reinforced plastics, fiber reinforced metals, etc. ②Sandwich composite materials. It is composed of surface materials and core materials with different properties. Usually the surface material is high in strength and thin; the core material is light and low in strength, but has a certain stiffness and thickness. It is divided into two types: solid sandwich and honeycomb sandwich. ③Fine-grained composite materials. Distribute hard fine particles evenly in the matrix, such as dispersion-strengthened alloys, cermets, etc. ④Hybrid composite materials. It consists of two or more reinforcing phase materials mixed in one matrix phase material. Compared with ordinary single-reinforced phase composite materials, its impact strength, fatigue strength and fracture toughness are significantly improved, and it has special thermal expansion properties. It is divided into intra-layer hybrid, inter-layer hybrid, sandwich hybrid, intra-layer/inter-layer hybrid and ultra-hybrid composite materials. Composite materials can be mainly divided into two categories: structural composite materials and functional composite materials. Structural composite materials are materials used as load-bearing structures. They are basically composed of reinforcement components that can withstand loads and matrix components that can connect the reinforcements to form a whole material and also transmit force. Reinforcements include various types of glass, ceramics, carbon, polymers, metals, natural fibers, fabrics, whiskers, sheets and particles, etc., while the matrix includes polymers (resins), metals, ceramics, glass, carbon and Cement etc. A wide variety of structural composite materials can be composed of different reinforcements and different matrices, and are named after the matrix used, such as polymer (resin)-based composite materials. The characteristic of structural composite materials is that component material selection and design can be carried out according to the stress requirements of the material in use. More importantly, composite structure design, that is, reinforcement arrangement design, can reasonably meet the needs and save materials. Functional composite materials are generally composed of functional components and matrix components. The matrix not only plays a role in forming the whole, but also can produce synergy or enhance functions. Functional composite materials refer to composite materials that provide other physical properties in addition to mechanical properties. Such as: conductive, superconducting, semiconducting, magnetic, piezoelectric, damping, wave absorption, wave transmission, friction, shielding, flame retardant, heat protection, sound absorption, heat insulation, etc. to highlight a certain function. Collectively called functional composite materials. Functional composite materials are mainly composed of functional bodies, reinforcements and matrix. The functional body can be composed of one or more functional materials. Multifunctional composite materials can have multiple functions. At the same time, it is also possible that new functions will be generated due to compound effects. Multifunctional composite materials are the development direction of functional composite materials. Composite materials can also be divided into common and advanced categories. Commonly used composite materials such as fiberglass are composed of low-performance reinforcements such as glass fibers and ordinary polymers (resins). Due to its low price, it has been developed in large quantities and has been widely used in ships, vehicles, chemical pipelines and storage tanks, building structures, sporting goods, etc. Advanced composite materials refer to composite materials composed of high-performance reinforcements such as carbon fiber, aramid and other high-performance heat-resistant polymers. Later, metal-based, ceramic-based and carbon (graphite)-based and functional composite materials were also included. Although their performance is excellent, their prices are relatively high. They are mainly used in the defense industry, aerospace, precision machinery, deep submersibles, robot structural parts and high-end sporting goods. 6.
