本研究之目的為探討純鋁粉末以及添加碳纖維作為粉末冶金的複合材料。本實驗主要區分為個兩個部分，第一個部分為壓鑄實驗，另外添加重量百分比為1w%、1.5w%、2w%之碳纖維，並與鋁粉放至球磨機24hr使其均勻分散之後再進行壓鑄實驗，壓鑄實驗使用手動液壓式壓錠機進行實驗，壓鑄大小分別為2噸、4噸、6噸，並以不同密度作為區分。
第二部分為燒結實驗，將壓鑄完的試片在管型氬氣高溫爐 中，先抽至真空再通入氬氣(99.99%純度以上)之後分別加熱至400°C、500°C、600°C、630°C下燒結，加熱時間為20分鐘，燒結完成後自然爐冷，之後再進行量測。
研究結果顯示最佳的壓實壓力為6t，最佳的燒結溫度為630°C，燒結時間為20分鐘，本實驗認為碳纖維本身密度較低，所以添加過多的碳纖維會使整體密度下降，高比例碳纖維在高溫時利於膨脹，然而在低溫時則無直接影響且高比例的碳纖維在溫度越高的情況下會使得密度逐漸下降，高比例碳纖維不利於高溫的燒結，而在低比例碳纖維溫度越高時密度也會隨之增高因此判別低比例碳纖維有利於高溫的燒結。

The objective of this research is to study aluminum added with carbon fiber for powder metallurgy. At first, the aluminum powder added with 1w%, 1.5w%, 2w% carbon fiber in the ball mill for 24 hours, and samples were pressed over a
wide range of pressures from 2 tons to 6 tons.
The second part is the sintering experiment, the samples were placed in a stainless steel tray and sintered in a flowing argon atmosphere with a reported purity of 99.99%.Sintering was done in the range of 400–630 °C and the post sinter cooling was performed by a furnace cooling to the room temperature.
The sintering response and mechanical properties of the alloy were investigated in laboratory settings. It was determined that compaction at 6 tons and sintering at 630 °C for 20 min produced the best properties in the sintered product.
Carbon fiber itself has a low density, so adding too much carbon fiber will reduce the overall density. High proportion of carbon fiber promotes expansion at high temperatures, resulting in a gradual decrease in density. However, there is no direct impact at low temperatures. Therefore, the discrimination of low proportion carbon fibers is advantageous for sintering at high temperatures.
