| Abstract | ||
| Tensile modulus and strength of 60% constant volume fraction of carbon fiber reinforced aluminum matrix composite materials have been investigated under room temperature (RT), zero °C, -15 °C and -30 °C using Testometric M500 tensile testing machine equipped with an environmental chamber. Three samples of different laminate arrangement and orientation were employed, namely S1and S2, which included both woven and unidirectional fibers, and S3, which contained only unidirectional fibers. The results showed that the tensile modulus was slightly increased with decreasing temperatures. The tensile strength showed a slight decrease for samples S1 and S2 with decreasing temperature, but for sample S3, the tensile strength increased as the temperature decreased from (RT) to -15 °C and then decreased at -30 °C. The S3 laminate orientation with only unidirectional carbon fibers possessed the highest tensile modulus and strength. | ||
