浮力材料具有密度低、机械强度高等优点,在航空航天和深海等工程领域的应用越来越广泛。采用3种空心玻璃微珠制备了一系列浮力材料,研究了在不同静水压环境下(6～26MPa)浮力材料的吸水率和体积形变。结果表明:随着静水压力的升高,浮力材料的吸水率增大;表面未被涂料包覆的浮力材料体积基本不变,表面被涂料包覆的浮力材料体积先保持不变后急剧缩少。
Syntactic foams are widely used in aerospace and marine engineering due to the low density and high mechanical strength.A series of syntactic foams were prepared with three kinds of microspheres,and the water absorption and volume change of the foams were studied at different hydrostatic pressures (6～26MPa).The results indicated that the water absorption rised with the increase of the hydrostatic pressure,and the volumes of the foams uncoated with paints remained unchanged,while those coated exhibited the follow trend:changed slightly first and then decreased dramatically.
