微玻璃珠（Micro-glass particle）加強材與矽膠（Silicone）基材之複合材料，具有成型時間短、質量輕、強度增強的效果，本文即針對此一材料，改變不同基材含量和加強材顆粒大小，利用實驗的方法探討其機械性能。
選用不同顆粒（50μm、150μm、300μm）與不同比例（5％、10％、20％、30％）所組成的顆粒強化複材進行實驗，由拉伸實驗求得彈性係數（E）、極限強度（σult）與極限應變（εult）。由粗糙度實驗求得中心線平均粗糙度（Ra），高溫氧化實驗得知複材在高溫下的重量減少百分比，硬度實驗求得複材的蕭氏硬度值（Hs），再利用電子顯微鏡SEM觀察試片破壞情形以及複材的成分分析。
由實驗結果得知，極限強度（σult）與彈性係數（E）和微珠含量相關，含量越高則強度越強、彈性係數（E）越大，當含量增加時極限應變（εult）則越小，改變微珠顆粒大小則不影響其結果。在硬度方面提高微珠含量，蕭氏硬度（Hs）也相對提高，改變顆粒大小則無影響，在粗糙度部分中心線平均粗糙度（Ra）隨著微珠百分比增加變大，而相同百分比中，微珠顆粒較大者Ra值也較大。在70度的高溫老化溫度中，添加微珠之複材重量保持性優於不添加微珠之複材。由SEM觀察下微珠之完整性良好、表面粗糙與Silicone之結合性佳，成分分析下微珠與Silicone結合後並無發生化學變化，也無產生其他雜質。

he composite material of enhanced micro-glass particles and silicone has some unique features that can be formed in shorter time with lighter weight and extraordinary consistency. In that article, by changing the amount of each component in percentage and the size of the particles are studied the physical attributes of the composites.
Various size of particles (50μm, 150μm, 300μm) and various amount of component (5%, 10%, 20%, 30% ) are applied in the experiment. From tensile test the value of elasticity modulus（E）, ultimate stress（σult）are obtained, and ultimate strain（εult）. From roughness test, the value of roughness average（Ra）are acquired. In aging test, from calculation of the value of composites under high temperature, obtained the ratio of weight decreasing in percentage. the value of shore hardness（Hs）are obtained from hardness test. Finally the components of the composites and the condition of destruction of types are analyzed by using scanning electron microscope（SEM）.
The results have indicated that ultimate stress（σult）and elasticity modulus（E）are interrelated to the amount of Micro-glass particles. The more the amount of particles is, the higher intensity of ultimate stress（σult）and the larger value of Elasticity modulus（E） there goes; On the contrary, the smaller value of ultimate strain（εult）it turns out. The result are the same even though size of particles is changed. In the test of Hardness; the more the amount of particles is, the larger value of shore hardness（Hs）it goes. again there has no effect to the results by changing the size of particles. In the roughness test, the more the amount of particles in percentage, the larger value of roughness average（Ra）it is. If the condition of the amount of particles remains the same, The value of roughness average（Ra）increase with the size of particles comes with larger. In the aging test with 70 degrees in celsius, the composites contained with micro-glass particles perform better in weight keeping than the composites without micro-glass particles. The condition of the conjunction of the particles and silicone in the composites had no conflicts and was formed in perfect shape under the observation of SEM. By analyzing the content of composites, there is no chemical reaction occurred neither any impurity was produced after binding the particles with silicone.
