处理对粘胶基炭纤维材料及其炭／树脂和炭／炭复合材料性能的影响

THE EFFECT OF TREATMENTS ON THE PROPERTIES OF RAYON-BASED CARBON FIBROUS MATERIALS AND THEIR CARBON PLASTICS AND C/C COMPOSITES

对各领域应用的C/P、C/C炭纤维复合材料制备工艺（学）的缜密考虑，需要知道：与基质反应的基体表面积及其物理—力学性能水平。探讨了炭纤维材料的真比重、比表面积及其物理—化学因素形貌特征的影响：诸如热处理温度（HTT）和在不同电流强度（I）电解液中电化学处理条件，这一处理，使CF表面件随含氧官以团的形成而激活，从而提高基质与C/P、C/C复合材料中CF的结合力。

The elaboration of production technologies of carbon plastics (CP) and C/C composites based on carbon fibers (CF) for various applications requires knowledge of the filler surface area interacting with the matrix and its physico mechanical properties. There has been investigated the effect on pycno metric ('real'ρ r) density and specific surface area (S α) of carbon fibrous materials and its morphology of various physico chemical factors: temperature of heat treatment (HTT) and conditions of electrochemical treatment (ECT) in an electrolyte at different current strength at which the activation of the CF surface occurs accompanied by the formation of functional O containing groups thereby increasing the cohesion between the matrix and CF in CP and C/C composites.
