间隔织物增强复合材料的隔热性能研究

Study on Thermal Insulation Properties of Spacer Fabric Reinforced Composites

以无碱玻璃纤维纱为原料,设计了3种不同结构的间隔织物,并在SGA598型全自动剑杆织样机上成功试织。以沉淀法白炭黑粉体作为隔热填料制备复合材料,对不同结构、不同白炭黑填充量的间隔织物增强复合材料的隔热性能进行了测试,结果表明:间隔织物的结构主要影响复合材料的隔热均匀性,蜂巢状和三角形间隔织物的隔热均匀性要优于双层间隔织物;随着隔热材料填充量的增加,织物的温升曲线明显降低。

Three kinds of spacer fabrics with different structures were designed with alkali-free glass fiber yarn as raw materials,and they were successfully woven on the SGA598 full-automatic rapier loom prototype.Precipitation method silica powder was used as the thermal insulation filler to prepare composite materials,and the thermal insulation performance of spacer fabric reinforced composite materials with different structures and different silica filling contents were tested.The results show that the structure of the spacer fabric mainly affects the insulation uniformity of the composite material,and the honeycomb and triangular spacer fabrics are better than the double-layer spacer fabric.With the increase of insulation material,the temperature rise curve of the fabric decreases obviously.
