Abstract

The thermal management of electronic devices is a critical component of their performance. Due to the emergence and evolution of new technologies, the wide use of electronic devices is increased in the past decade in the field of marine, automobile and other stationary applications. The need for effective thermal management in these applications has become more critical. This paper aims to provide a comprehensive overview of the various challenges that face the development of new composite materials, as epoxy-based composites are the latest trend of materials widely used in many areas. But their thermal conductivity behaves poorly in moisture and thermal conditions. This work attempts to study the behaviour of silicon carbide and E glass fiber reinforced polymer matrix composite under hygrothermal and compressive loads. Specimens are also tested for moisture absorption to calculate the hygro strains of a specimen. E-glass fiber is fixed to 15% and varied 10%, 20% and 30% of SiC in the fabrication of hybrid polymer composite using the hand-layup technique. These specimens undergo tensile, flexural, hardness and thermal conductivity tests, revealing the tensile strength, thermal, flexural strength, hardness and thermal conductivity of proposed specimens. The behaviour of the specimens is compared for all conditions with moisture at room temperature, 80 deg C and 150 deg C.

湿热条件下碳化硅基聚合物复合材料热行为的实验研究
电子器件的热管理是其性能的关键组成部分。由于新技术的出现和发展,在过去的十年中,电子设备在船舶,汽车和其他固定应用领域的广泛使用有所增加。在这些应用中,对有效热管理的需求变得更加关键。本文旨在全面概述新型复合材料发展所面临的各种挑战,因为环氧基复合材料是在许多领域广泛应用的最新趋势材料。但其导热性能在湿热条件下表现较差。本工作试图研究碳化硅和E玻璃纤维增强聚合物基复合材料在湿热和压缩载荷下的性能。还测试了样品的吸湿性,以计算样品的湿应变。采用手工叠层技术制备杂化聚合物复合材料时,e -玻璃纤维固定为15%,SiC含量分别为10%、20%和30%。这些试样经过拉伸、弯曲、硬度和导热性测试,揭示了建议试样的拉伸强度、热强度、弯曲强度、硬度和导热性。在室温、80℃和150℃的湿度条件下,比较了试样的行为。
