摘　　要：设计了一套基于压差流量法的试验装置来测量玻璃钢试样的放气速率。将试样的表面采用砂纸(500#)进行打磨,采用扫描探针显微镜对试样表面粗糙度进行测量。测量了不同温度下玻璃钢试样的放气速率。试验结果表明测量室温度越高,测量室的气体压力越高,玻璃钢试样的放气速率越大。An experimental system based on head metering was designed to measure the outgassing rate of glass fiber reinforced plastics （GFRP） at different temperatures. The GFRP samples were ground by ^# 500 abrasive paper, then the surface roughness of sample was measured by a scanning probe microscope. The outgassing rate of GFRP was measured at different temperatures. The experimental results showed that the higher the measurement chamber temperature, the higher the outgassing rate of GFRP.
