| 摘 要： | 电导实验表明：有机硅的加入对合成的酚醛树脂的交联密度有影响.改性酚醛树脂的各项常规指标均优于普通酚醛树脂,其中残碳率可以达到50.75%,比普通酚醛树脂的残碳率（40.80%）提高了近10%.FESEM照片可以看到有机硅改性酚醛树脂在800℃碳化后生成了碳纤维,而且所生成半径大致为350～450 nm的SiO2粒子分布... |

Study of the phenolic resin modified by organo silicon |
|
| Abstract: | Conductance experience showed that the crosslinking density of the synthesis phenolic resin was influenced by adding organosilicon.The normal detection indexes of the phenolic resin modified by the organosilicon were better than the normal phenolic resin.Comparison to the unmodified phenolic resin,the residual carbon of the modified phenolic resin reaches to 50.75% and increases about 10%FESEM images show that fiber-like carbon were formed from the modified phenolic resin after carbonization under 800 ℃.The SiO2 with diameter in 350～450 nm are distributed uniformly and bind with matrix carbon well.The mechanical quality of the phenolic resin is reinforced by the organic-inorganic hybrid material modify. |
