1. Introduction

With the deepening of marine exploration and underwater operations, the requirements for diving equipment are also increasing. Especially for deep-sea diving, it is necessary to have extremely strong pressure resistance to ensure the safety and comfort of divers. As a new material, SBR composite fabric has been widely used in deep-sea diving equipment due to its excellent pressure resistance and flexibility. This article will introduce in detail the pressure resistance technology of SBR composite fabrics and its application in diving at different depths.

2. Overview of SBR Composite Fabrics

2.1 Material composition and structure

SBR composite fabrics are mainly composed of styrene Butadiene Rubber (SBR), nylon fiber and other reinforcement materials. Its structural design is designed to provide high strength, wear resistance and good elasticity while maintaining low weight and high flexibility. Table 1 lists the main components and functions of SBR composite fabrics:

2.2 Manufacturing process

The manufacturing process of SBR composite fabrics includes multiple steps, such as raw material mixing, spinning, weaving and post-treatment. These steps ensure the uniformity and stability of the material. The specific process flow is as follows:

1. Raw material preparation: Mix SBR, nylon fiber and other raw materials in proportion.
2. Spinning: Through high-temperature melt spinning technology, the mixed raw materials are made into fibers.
3. Weaving: Weave fibers into fabrics using advanced textile equipment.
4. Post-treatment: Perform waterproofing, anti-fouling and other treatments to improve material performance.

3. Principles of pressure resistance technology

The pressure resistance of SBR composite fabrics depends mainly on their unique microstructure and material properties. According to the research of the famous foreign document “Materials Science and Engineering”, the SBR molecular chain has a highly crosslinked structure and can remain stable under high pressure environments. In addition, the addition of nylon fiber further enhances the tensile strength of the material, making it less likely to deform or break when under heavy pressure.

Study shows that SBR composite fabrics can effectively disperse stress in high-pressure environments, reduce local stress concentration, and thus improve overall pressure resistance. This feature makes SBR composite fabrics ideal for deep-sea diving equipment.

4.1 Basic physical properties

Table 2 shows the basic physical performance parameters of SBR composite fabrics:

4.2 Voltage resistance performance test

To verify the pressure resistance of SBR composite fabrics, the researchers conducted several experiments. Table 3 lists the results of pressure withstand voltage tests at different depths:

It can be seen from Table 3 that SBR composite fabric has excellent pressure resistance performance at different depths, and can maintain good shape and function even at a depth of 1000 meters.

5. Application cases for diving needs at different depths

5.1 Shallow sea diving (0-100 meters)

Shallow sea diving usually does not require extremely high pressure resistance, but still requires certain protective measures. SBR composite fabric is very suitable for the production of shallow sea wetsuits due to its lightweight, soft and good water resistance. For example, the shallow sea diving suit used by the US Navy uses SBR composite fabric, which not only provides a comfortable wearing experience, but also effectively prevents seawater erosion.

5.2 Medium-depth diving (100-500 meters)

Medium-depth diving requires high pressure resistance for equipment, especially when the water pressure gradually increases. The high strength and wear resistance of SBR composite fabrics make it ideal for medium-depth diving suits. According to Journal of Marine Science and Technology, a medium-depth diving suit with SBR composite fabric performed well in actual use, able to withstand pressures up to 500 meters and without obvious damage.

5.3 Deep sea diving (500-1000 meters)

Deep sea divingWater is one of the important application scenarios for SBR composite fabrics. In extreme high pressure environments, the pressure resistance and stability of the material are crucial. According to research by Deep Sea Research Part I: Oceanographic Research Papers, an SBR composite fabric diving suit designed for deep-sea diving successfully completed a 1000-meter depth test, showing excellent pressure resistance and reliability.

6. Current status of domestic and foreign research

In recent years, domestic and foreign scholars have made significant progress in research on SBR composite fabrics. Foreign, Advanced Materials magazine published a series of research papers on SBR composite materials, exploring its application prospects in different fields. In China, the Department of Materials Science and Engineering of Tsinghua University has also carried out related research and published many high-level papers, which has promoted the development of SBR composite fabric technology.

7. Conclusion and Outlook

To sum up, SBR composite fabrics have shown broad application prospects in the fields of diving at different depths with their excellent pressure resistance and versatility. In the future, with the continuous development of materials science, SBR composite fabrics are expected to play an important role in more fields, such as deep-sea exploration and subsea resource development. Researchers will continue to work to improve the integrated performance of materials to meet growing demand.
