中文摘要：

为了实现铝与碳纤维的无界面反应复合,以无涂层处理的碳纤维编织布和纯铝粉为原料,在低温下通过超声辅助加压复合法成功制备了碳纤维增强铝基复合板.利用0M、SEM、XRD和电子万能试验机等分析测试手段研究了热压温度对复合板的界面微观结构和力学性能的影响.结果表明：热压温度为600尤时,碳纤维与铝基体仍呈分离状态;当温度达到铝基体熔点660尤时,碳纤维出现明显灼烧,界面处出现脆性相Al4C3;而热压温度为接近熔点的640尤时,在超声的作用下,碳纤维与固态的铝基体能很好地浸润,界面处无脆性相Al4C3生成,界面的结合方式主要以溶解与润湿结合为主,部分区域为机械结合,复合板的界面结合性能和拉伸性能达到最高值,主要可以归结于载荷的传递作用和位错的强化作用.

英文摘要：

Aluminum composite plates reinforced by a carbon fiber woven cloth without coating processing were fab-ricated by ultrasonic-assisted hotpressing at low temperature. Th e influences of hotpressing temperature on the inter-facial microstructures and mechanical properties of carbon fiber-reinforced aluminum composite plates were investi-gated by 0 M , SEM , XRD,and an electronic universal testing machine. Results showed that the carbon fibers re-mained separate from the aluminum matrix at hotpressing temperatures as high as 600^. W h e n the temperature rose to 660^,the carbon fibers were seriously burned, and a brittle A U C 3 phase developed at the interface between these fibers and the aluminum plate. At 640^,the carbon fibers were infiltrated with aluminum under the action of ultrasonic waves and no brittle ALC3 phase was found at their interface. T he combination m o d e of the interface mainly included dissolution and wetting; however,mechanical combination was observed in some areas of the plate. The performance of the combined interface and the tensile strength of the composite plate could be mainly attributed to load transfer and dislocation strengthening effects.
