1975年日本东北大学矢岛圣使教授等人用聚碳硅烷作原料通过纺丝法研制出成束的连续细SiC纤维。据报导,这种SiC纤维在强度、模量、耐腐蚀性、抗氧化、高温性能等方面与CVD法(化学气相沉积法)制备的SiC纤维差不多。同Al、Ti、Ni等金属以及陶瓷复合有明显的增强效果。 为了确认日本这种SiC纤维性能的高低、质量的优劣,我们对该纤维的某些性能进行了试验、检测。 试验与结果 1.纤维室温性能分析 该纤维商品名称为Nicalon。纤维束浸过胶。经红外分析表明此胶为聚醋酸乙烯酯(C_4H_6O_2)x,含胶量约为2％,可用适当的
In 1975, Professor at Japan Tohoku University Yajima Shinto et al. Used polycarbosilane as a raw material to prepare bundles of continuous fine SiC fibers by a spinning method. It has been reported that the SiC fiber is similar in strength, modulus, corrosion resistance, oxidation resistance and high-temperature properties to the SiC fiber prepared by the CVD method (chemical vapor deposition method). With Al, Ti, Ni and other metal and ceramic composite has a significant enhancement. In order to confirm the performance of Japan, such as SiC fiber, the quality of the pros and cons, we have some of the properties of the fiber were tested and tested. Tests and Results 1. Fiber Room Temperature Property Analysis The fiber trade name is Nicalon. Fiber bundle soaked plastic. Infrared analysis showed that the glue is polyvinyl acetate (C_4H_6O_2) x, with a gel content of about 2%
