Alpine Advanced Materials has completed Electromagnetic Interference (EMI) testing on HX5 and found the lightweight aviation grade thermoplastic nanocomposite to have exceptional attenuation when bare or plated with various thicknesses of nickel and copper. The highly engineered HX5 has already demonstrated its strength and performance for use in complex components, but the results of the EMI testing make it an even more attractive material for use in electronics.
EMI是由电子设备向另一个设备发送射频或电磁波的电子设备引起的，可能会破坏关键医疗，军事，航空航天，大众运输，车辆控制和导航系统中使用的电子设备，设备和系统。屏蔽障碍电磁场具有诸如HX5之类的障碍物，可满足电磁兼容性要求，以确保可靠的系统性能。
Alpine Advanced Materials总裁Roger Raley说：“我们的EMI测试结果令人惊讶，因为热塑性塑料通常会衰减很小。”“高衰减是指用HX5制成的零件可防止无线电和电子频率相互干扰。我们知道HX5有多强，但是这些发现增加了其上级处理方面的证据。”
两个独立的实验室测试了涂层和裸照HX5，以研究膜厚度与衰减之间的关系，从10kHz到40GHz。使用的测试规格包括：IEEE 299-2006，MIL-STD-285。
“We found that HX5 can be plated for EMI shielding at a range of 12kHZ to 40GHz, and secured data for electrical surface and volume resistivity for bare and plated HX5, confirming both electroless plating for EMI shielding and shielding effectiveness,” added Marinela Peto, Mechanical Engineer for Alpine Advanced Materials. “In fact, test results showed comparable and even higher attenuation levels for bare HX5 versus plated samples for certain frequencies from 12GHz to 40GHz.”
With a high strength-to-weight ratio, thermal stability, environmental resistance, and manufacturing flexibility, HX5 can be injection molded, formed, extruded or machined like aluminum. It allows component manufacturers to make complex shapes with a specific strength (ratio of tensile strength divided by density) twice that of aluminum on a weight to weight basis.
Developed over more than a decade of testing and validation by the Department of Defense with an R&D investment in excess of $50 million, HX5 was engineered to replace machined aerospace-grade aluminum at half the weight. Earlier this year, it was shown in third-party testing to retain up to 96% of its original mechanical performance when subjected to 5 million rads of gamma radiation. It has also demonstrated extreme corrosion resistance to solvents, fuels, lubricants, and chemicals, giving it the ability to withstand the most demanding applications. Already certified for use from rockets and satellites to amphibious transport vehicles, HX5 is an ideal alternative to aluminum at half the weight and multiple times the manufacturability.
