Abstract
A composite,PCM-GF,composed of cement-polyethylene glycol phase change material(PCM)and glass fiber-reinforced polymer(GF),was prepared,and its thermal and mechanical properties were investigated.Differential scanning calorimetry and thermal conductivity tests revealed that as the mass of GF increased from 0 g to 800 g,the specific melting enthalpy and specific crystallization enthalpy of PCM-GF decreased from 178.85,179.61 J/g to 52.87,53.11 J/g,respectively,while the thermal conductivity increased from 0.13 W/(m·K)to 1.85 W/(m·K).The results indicated that the specific phase change enthalpy of PCM-GF was linearly inversely proportional to the mass fraction of GF in the composite,and the addition of GF enhanced the thermal conductivity of the PCM-GF composite enhanced laminated plate.The incorporation of GF improved the mechanical properties of the PCM-GF composites.The prepared PCM-GF composite can serve as an energy-saving,indoor temperature-regulating roofing building material.关键词
