With the composite material technology matures,[link widoczny dla zalogowanych], the aging behavior of composite materials has increasingly become the focus of attention]. through time analysis, we can know the reinforcement fibers on the matrix Taijin kinetics of aging. In this paper, silicon acid aluminum short fiber / ZL109 composite microstructure were analyzed to study its aging characteristics, and were compared with the ZL109 alloy. 2 Experimental Methods Experimental silicate short fibers used in chemical composition and performance indicators such as Table 1 said. ZL109 Taijin the chemical composition shown in Table 2. aluminosilicate short fibers made of prefabricated parts,[link widoczny dla zalogowanych], into a pre heated in metal type, and into the molten liquid alloy ZL109. short aluminum composite material fiber volume fraction (,) is 32. on the Preparation of the composite material sample, the polished, polished, etched in the Camera for Olympus microscope to observe the microstructure and photographed. Kim ZL109 the solution heat treatment (500 ± 5 ℃ × 5h, water quenching); 160,180, respectively, after solution treatment and aging 200 ℃ for 12h heat treatment, at regular intervals by removing a sample of a 3000 HB Brinell hardness tester hardness set O f (load 49N,[link widoczny dla zalogowanych], ball diameter and 5mm), take 4 to 5 points on average. 3 Table 1 Experimental results and analysis of performance parameters of aluminosilicate short fiber tray table 2ZL109 Taiwan Wei min () SilMgllFeIMnAI11.0 ~ 13.0 } 0.8 ~ 1.5f0.5 ~ 1.5f05f0f margin 3.1 Microstructure of composite materials Preparation of the composite microstructure shown in Figure 1. fiber and the matrix of the interface is clear, no holes, combination of both is better, the distribution of reinforcement fibers is also more evenly in the matrix was disordered state distribution. From the figure can be seen in the fiber and matrix interface, there is a 410 SX fiber used box resistance furnace of the composites and matrix co-M .35 years old. Master. 12 lecturers of a \
