摘要
Abstract
In order to study the mechanical properties of new composite insulation board,the mechanical properties of composite insulation template were designed and tested.The results show that the extruded polystyrene com-posite insulation board has wrinkles around the specimen in the process of compression,but no obvious cracks.Rock wool composite insulation board in the process of compression,rock wool fibers bend or break,into strips separated from each other.Fillet rock wool composite insulation board with pressure action,be-tween the fibers extrusion compaction,showing a strong compressive ability.Folds appear around the graphite polystyrene composite insulation board during compression.In a certain range,the elastic modulus and com-pression strength of composite insulation board increase with the increase of the thickness of the thermal insu-lating material.The elastic modulus and compression strength of the thermal insulating material of extruded polystyrene board are higher than that of the graphite polystyrene board.关键词
