玻璃纤维具有质轻、不易老化、不腐、不蛀、取材方便、造价低廉等优点,已广泛地用作保温、吸声材料。由于它有较好的弹性,国外早已用作减振材料,我国亦在不少隔振工程中使用了这种材料。玻璃纤维的隔振效能来源于纤维之间空隙压缩而产生的弹性,材料的阻尼来源于纤维之间的内摩擦。它对化学反应不敏感,亦不会燃烧,并具有抗酸碱和耐油的良好性能。当在玻璃纤维上施加的荷载超出最大使用荷载时,永久变形亦较小。但玻璃纤维只能在力的作用方向垂
Glass fiber has the advantages of light weight, less aging, no rot, no blemishes, convenient materials, and low cost, and has been widely used as a heat-insulating and sound-absorbing material. Because it has better flexibility, it has been used as a damping material in foreign countries. China has also used this material in many vibration isolation projects. The vibration-insulating effect of glass fiber stems from the elasticity resulting from the compression of the voids between the fibers, and the damping of the material results from the internal friction between the fibers. It is not sensitive to chemical reactions, it will not burn, and it has good properties of acid and alkali resistance and oil resistance. When the applied load on the glass fiber exceeds the maximum use load, the permanent deformation is also small. But glass fiber can only hang in the direction of force
