Technical exploration on avoiding the generation of bubbles and defects in the preparation process of radar absorbing materials

RAM (Radar Absorbing Material) has a wide range of applications in modern military equipment and civilian communication fields. This article introduces the research platinum brand radar absorbing material developed by Advanced Institute (Shenzhen) Technology Co., Ltd., and focuses on how to reduce or eliminate bubbles and other defects in the material by optimizing the preparation process, thereby improving its performance.

1. Introduction

With the development of electromagnetic compatibility and stealth technologyRadar absorbing materialThe demand is increasing day by day. However, bubbles and small defects are prone to occur during the preparation process, which can affect the effectiveness of the material. Therefore, researching how to avoid these problems is crucial for improving the quality of radar absorbing materials.

2. The impact of bubbles and defects

• Bubbles: Air gaps that exist inside materials can reduce absorption efficiency because they alter the dielectric properties of the material.
• Defects such as cracks, delamination, and other structural discontinuities may lead to a decrease in mechanical strength and may also become new scattering sources, weakening the absorption effect.

3. Characteristics of Platinum brand Radar Absorbing Materials

Developed by Advanced Institute (Shenzhen) Technology Co., LtdResearch Platinum Brand Radar Absorbing MaterialsIt has the following advantages:

• Efficient electromagnetic wave absorption capability;
• Broadband response;
• Good environmental stability;

4. Challenges and Solutions in the Preparation Process

4.1 Component selection and mixing

• Component selection: Choosing appropriate fillers and matrix resins is crucial. For example, using high-density magnetic particles can increase the weight of the material and help reduce bubble formation; And specific types of adhesives can enhance the overall integrity of the material.
• Mixing process: The use of vacuum stirring equipment can effectively remove air during the mixing process, ensuring uniform dispersion of each component while preventing the introduction of new bubbles.

4.2 Pouring and Curing

• Pouring method: Adopt appropriate pouring speed and pressure control to avoid residual bubbles caused by too fast or too slow pouring.
• Demoulding treatment: Using flexible molds and curing at appropriate temperatures can reduce cracks or other forms of defects caused by shrinkage stress.

4.3 Heat treatment process

• Heating rate: Slow heating and cooling can reduce deformation or cracking caused by thermal stress.
• Insulation time: A sufficiently long insulation period helps to release internal stress in the material and ensure the structural integrity of the final product.

4.4 Surface Treatment

• Polishing and Grinding: For applications with high surface requirements, fine polishing and grinding can eliminate external defects and improve appearance quality.
• Coating protection: Adding a weather resistant protective coating can not only prevent external factors from corroding, but also further optimize electromagnetic performance.
