Abstract: A form of static coupon following the boat was developed to carry the natural aging test for CF3011/BA9916-II composite in marine environment, and the weather resistance of composite in marine climate was studied. The changes of the morphology of the composite were observed, the changes of the quality ,tensile strength and interlaminar shear strength for specimen were analyzed, and the aging regulation was studied combining with the mechanism of hygrothermal aging for carbon fiber epoxy composite. The test results showed that with the aging time increasing, the moisture absorption of the composite increased, the mechanical strength decreased , and the plastic behavior of the material was showed.

Power Operation

The reliability of optical sources is strongly dependent on the degradation and device characteristics are critically dependent on temperature. The degradation behaviours and reliability test results for the laser diode device (Sony-DL3148-025) will be presented .These devices are usually highly reliable. The degradation behaviour was exhibited in several aging tests, and device lifetimes were then estimated. The temperature dependence of 0.63?m lasers was studied. An aging test with constant light power operation of 5mW was carried out at 10, 25, 50 and 70°C for 100hours. Lifetimes of the optical sources have greatly improved, and these optical sources can be applied to various types of transmission systems. Within this degradation range, the device life for system application is estimated to be more than 100 h at 70 ºC at a constant power of 5mW.

Rate Sensor

In this work, an ASIC interface for quartz rate sensor (QRS) is introduced. Based on 0.6μm 18V N-well CMOS process, it is the first to be realized in the domestic. This chip has a minimized size of 5×4.4mm2. Compared with traditional interface constructed by separate devices, such interface implemented with integrated circuits is advantageous in size and power consumption. This satisfies the requirements of miniature and low power consumption in space industry and military domain. The test results show that this interface features low noise, high linearity, and stable operation. Integrated with the sensor, the entire system presents high performance in short term bias stability, nonlinearity, output noise, bias variation over temperature, and power consumption.

The electron beam radiation method is emitted by electronic accelerators, which can change the chemical physical properties of radiation. Silicone rubber samples after different irradiation intesities were carried out for the 1000h aging test, and the electronic scanning microscopy (SEM), mechanical tensile and hydrophhy angle of the silicone rubber sample were measured, the test results shows that: after 1000h aging test, the visual apperence of the sample did not changed, the SEM showed that the surface of the silicone rubber became rough and the porosity increased, and the mechanic tension decrease. For moderate Irradiation intensity(60KGy), the aging characteristics of silicon rubber can be improved.
