Polymer composites have been a material of choice for lightweight and durable applications in industrial sectors including automobile, electronics, structural components, etc. Especially, for automotive applications, functional polymer composites with high-performance in reducing electronic noise and electromagnetic interference (EMI) are highly required. Thermotropic liquid crystalline polyesters (TLCPs) with rigid main chains of wholly aromatic rings linked by ester groups are well known for their high performance in mechanical strength, modulus, thermal stability. For the purpose, we have investigated the TLCP-based composites reinforced with different contents of chopped carbon fiber (CF), which are fabricated by melt-compounding method. The morphological features of TLCP/CF composites are identified by SEM and XRD analyses. The thermal, mechanical, electrical, and EMI shielding properties of the composites are investigated with DSC, TGA, DMA, electrometer, and network analyzer. |
