四向织物增强碳一碳复合材料的研究工作正在进行中。这种复合材料是为制造在工作时承受很高的热应力的零、部件而专门设计的。本文概要地描述了四向织物并指出它与三向、七向、十一向相比较所具有的优点。四向织物是用单向碳纱按“抽拉工艺”制得的杆制造的,复合研究证明沥青在压力下浸渍-碳化工艺是优越的。 Four-directional fabric reinforced carbon-carbon composites research work is underway. This composite material is specially designed for the manufacture of parts and components that withstand high thermal stress at work. This article describes the four-way fabric briefly and points out its advantages over three, seven, and eleven dimensions. Four-way fabrics are made from unidirectional carbon yarns drawn in a “draw-off” process and complex studies show that asphalt is impregnated under pressure - the carbonization process is superior.
