Preparation of Unidirectional Carbon Fiber Preform for Aluminium Matrix Composites

Abstract

The unidirectional carbon fiber (CF) preform for carbon fiber reinforced aluminium (CF/Al) composites has been investigated in terms of the fabrication condition and the strength property. The CF preform which consists of CFs and Cu particles was fabricated by spark plasma sintering (SPS) process with different fabrication temperatures. In order to determine the infiltration pressure of molten Al to the CF preform, the compression test was performed to the CF preform. The unidirectional CF preform by SPS process was well formed with the fabrication temperature condition at 1123 K in accordance with the formation of Cu particle bridging between fibers and Cu deposition on fibers. The compression strength of the CF preform increased with increasing fabrication temperature. Besides, the CF preform was deformed such as fiber micro-buckling or fiber kinking phenomena over the maximum compression strength. The infiltration pressure of the molten Al can be decided under the maximum compression strength.

Development of VGCF/MP Reinforced Al Matrix Composite by Low Pressure Infiltration Method and Their Thermal Property

“…Moreover, the full width at half maximum (FWHM) of (002) deceased from 5.280°to 1.528°. The decrease in FWHM of (002) indicated that the distance between carbon aggerates decreased, 14) resulting in higher phonon velocity in the porous VGCF/ MP. 15) To investigate the elemental distribution of VGCF/MP/Al composite (MP and 0.5 vol% VGCFs, after carbonization), EPMA was carried out in the same area as Fig.…”

“…세라믹/금속 복합재료에서 W a 는 금속과 세라믹 계면에서의 상호작용의 강도를 수치화 한 것이며 이는 세라믹/금속 복합재료의 기계적 특성을 모 델링할 때 항상 고려하는 부분이다 [7]. 현재 탄소섬유/알루미늄 복합재료 제조를 위해 많이 연 구되고 있는 방법으로는 squeeze casting법이나 infiltration 법 등이 있다 [8][9][10][11][12] …”

Effect of SiO2 amount on microstructures and tensile properties of alumina short fiber-reinforced composites by low-pressure infiltration method

“…Although the MMCs are very attractive materials for automobile industry, the raw materials and its manufacturing method are not cost effective compared with the conventional materials and its manufacturing system. However, the low-pressure infiltration method [5][6][7] is one of the useful casting methods for MMCs, due to apply low-pressure in comparison with high pressure casting such as die casting and squeeze casting. 8,9 Furthermore, low pressure is able to produce complex/ large shape and accomplish high cost-performance.…”
