In the field of modern precision manufacturing and high-end equipment, composite materials, with their \"1+1>2\" comprehensive performance advantages, are gradually replacing traditional single materials and becoming the core material driving product upgrading in various industries. They break the performance limitations of single materials and achieve complementary advantages through scientific compounding. Widely used in multiple high-end fields such as aerospace, automotive, medical devices, and electronic equipment, they are highly compatible with GSG-Tech's focused businesses of precision manufacturing, 3D printing, and precision machining, serving as a key support for achieving high precision, lightweight, and high performance of components.

I. Core Introduction to Composite Materials

Composite materials refer to new materials formed by combining two or more component materials with different physical and chemical properties through specific composite processes. Their core feature is to take advantage of the strengths of each component material and make up for the shortcomings of single materials — for example, combining the high strength of metals with the high temperature resistance of ceramics, and the easy processability of resins with the tensile resistance of fibers. Finally, they form comprehensive properties such as high strength, lightweight, corrosion resistance, fatigue resistance, and customizability, which are far superior to traditional materials such as single metals, plastics, and ceramics.

Compared with traditional materials, the core advantages of composite materials are reflected in three aspects: first, lightweight, with a density much lower than that of metal materials, which can greatly reduce product weight and meet the weight reduction needs of high-end equipment; second, customizable performance, which can adjust the proportion of component materials and composite processes according to the needs of different industries to achieve precise matching of properties such as strength, toughness, corrosion resistance, and thermal conductivity; third, easy processing and forming, which can be formed through various processes such as 3D printing, molding, and injection molding, suitable for the production of complex structure components, especially for the customized manufacturing of small precision parts, which is highly consistent with GSG-Tech's core business capabilities.

(I) Core Classification (Suitable for Precision Manufacturing Scenarios)

Combined with precision manufacturing, 3D printing, and GSG-Tech's multi-material processing business, composite materials are mainly divided into 4 categories according to the matrix material, covering the core material range that GSG-Tech can process:

1. Polymer Matrix Composites (PMC): With resins such as epoxy resin, phenolic resin, and polyurethane as the matrix, combined with reinforcing materials such as glass fiber, carbon fiber, and aramid fiber, it is the most widely used type of composite material. It has the characteristics of lightweight, easy processing, corrosion resistance, and moderate cost, and can be formed through processes such as 3D printing and molding, suitable for GSG-Tech's 3D printing and precision machining business. It is currently the most commonly used composite material in various industries.

2. Metal Matrix Composites (MMC): With metals such as aluminum alloy, titanium alloy, and copper alloy as the matrix, added with ceramic particles or fibers for reinforcement, it has both the high strength and high thermal conductivity of metals and the wear resistance and high temperature resistance of ceramics. It is compatible with GSG-Tech's multi-material processing capabilities, and the processing precision can meet the standards of precision manufacturing, suitable for scenarios with high requirements on strength and precision such as high-end mechanical parts and aerospace structural parts.

3. Ceramic Matrix Composites (CMC): With ceramics as the matrix, combined with reinforcing materials such as carbon fiber and silicon carbide fiber, it has extremely strong high temperature resistance, wear resistance, and corrosion resistance, and can withstand extreme working conditions (such as high temperature, high pressure, and strong corrosion environments). It is a key material in the fields of high-end precision manufacturing and special equipment, and is often used in aerospace engine components and high-end precision instruments.

4. Carbon Matrix Composites (CMC): With carbon as the matrix, reinforced with carbon fiber, it has the characteristics of high strength, lightweight, high temperature resistance, and excellent electrical and thermal conductivity, and its performance is far superior to traditional metal materials. It is often used in fields with strict performance requirements such as aerospace and high-end precision electronic equipment, suitable for GSG-Tech's high-precision part processing needs.
