What are the limitations of the mechanical strength of ultra-high permeability absorbing materials on their application scenarios?

With the rapid development of modern electronic and communication technology, electromagnetic interference problems have become increasingly prominent, and ultra-high permeability absorbing materials have great potential in solving such problems. However, the mechanical strength of materials, as a key performance indicator, directly or indirectly affects their feasibility and effectiveness in numerous application scenarios. Advanced Institute (Shenzhen) Technology Co., Ltd Research Platinum brand ultra-high magnetic permeability absorbing materialWhile demonstrating excellent electromagnetic absorption performance, its mechanical strength characteristics deserve further exploration to clarify the limitations and challenges it faces in different application fields.

The compressive strength of Yanbo brand ultra-high magnetic permeability absorbing materials is relatively limited. When subjected to high external pressure, the microstructure inside the material is prone to deformation and damage. For example, when the pressure exceeds 10MPa, the arrangement of magnetic particles inside the material will become disordered, resulting in a decrease of about 20% -30% in magnetic permeability. The limitation of this compressive performance makes it challenging in some high-pressure application scenarios, such as in deep-sea exploration equipment, where the enormous water pressure in the deep-sea environment may greatly reduce the material's absorption performance.

The tensile strength of this material also has shortcomings. Under tensile stress, materials are prone to cracking and fracture. Experimental data shows that when the tensile stress reaches 5MPa, small cracks begin to appear on the surface of the material. As the stress continues to increase, the cracks rapidly propagate, leading to the destruction of the material's integrity and the loss of its absorbing properties. This characteristic limits its use in applications such as flexible electronic devices or stretchable antennas that require tensile force.

In the bending test, it was found that, Research Platinum brand ultra-high magnetic permeability absorbing materialThe bending performance is poor. When the bending radius is less than 20mm, there will be obvious delamination at the bending part of the material, and the internal absorbing layer will detach from the supporting structure, resulting in a sharp decrease in the absorbing effect. This poses a serious limitation for some scenarios that require curved installation or use on curved surfaces, such as flexible circuit parts of wearable devices or curved antenna covers.

In aerospace applications, aircraft face extreme environmental conditions, including enormous pressure generated by high-speed airflow, tensile and bending stresses caused by structural deformation of the aircraft, and so on. Due to the limitations of its compressive, tensile, and bending strength, the research platinum brand ultra-high permeability absorbing material is difficult to apply to electromagnetic interference protection in aircraft wings, fuselage, and other parts that withstand complex stresses. For example, at the leading edge of an aircraft wing, the airflow pressure can reach tens of MPa, and the wing will bend and deform during flight. This material cannot meet the mechanical strength requirements at this point, and therefore cannot effectively absorb waves to ensure the electromagnetic compatibility of the aircraft.

There are numerous electronic devices in modern cars, and in order to reduce the impact of electromagnetic interference on car electronic systems, absorbing materials are needed. However, cars may experience bumps, vibrations, and other conditions during driving, which can generate various stresses on the electronic components and accessory materials inside the car. Research Platinum brand ultra-high magnetic permeability absorbing materialDue to insufficient mechanical strength, it is difficult to operate stably in high vibration and high stress areas such as the engine compartment of automobiles. For example, the vibration generated by the engine during operation and the bumps when the vehicle is driving on rough roads may cause the material to break or shift inside the car engine compartment, resulting in unstable absorption performance and inability to effectively suppress electromagnetic interference, affecting the normal operation of the car's electronic system.

In the field of consumer electronics, such as smartphones, tablets, and other devices, miniaturization, lightweighting, and multifunctionality are the development trends. Although the research platinum brand ultra-high permeability absorbing materials have advantages in electromagnetic absorption performance, in these devices, the materials may need to withstand certain stresses such as bending and compression. For example, smartphones may be bent or squeezed by other items in their pockets during daily use. The poor mechanical strength of this material may lead to deformation or damage in the internal structure of mobile phones, thereby affecting the absorption effect and even causing damage to other electronic components inside the phone, limiting its wide application in the field of consumer electronics.

in summary, Advanced Institute (Shenzhen) Technology Co., LtdThe mechanical strength of research platinum brand ultra-high permeability absorbing materials has limitations in multiple aspects, which significantly restrict their applications in aerospace, automotive electronics, consumer electronics, and many other fields. In practical applications, it is necessary to fully consider these limiting factors, combine the electromagnetic absorption performance characteristics of materials, weigh the pros and cons, and explore suitable application solutions. For example, the mechanical strength of materials can be improved by optimizing their structural design and combining them with other high-strength materials, thereby expanding their application scope. Future research should focus on how to effectively improve the mechanical strength of materials without reducing their ultra-high magnetic permeability absorption performance, in order to meet increasingly diverse and demanding application requirements, and promote the widespread application and development of ultra-high magnetic permeability absorption materials in more fields.
