摘　　要：将复合材料学科中本构预测方法引入建筑材料,通过对复合保温板基本单元模型进行假设,应用所假设的两种基本单元模型,结合热传导的理论给出了相应的预测公式,对保温板的保温性能进行了预测,并将预测结果与保温板实际保温性能进行对比,验证了假设模型的准确性.对于不同种类复合保温板的预设计、性能预测和导热机理的研究有着重要的意义.Constitutive prediction method about composite materials performance is introduced into building material,based on basic unit model assumptions of the composite thermal insulated board,applied two kinds of basic unit model assumed and combined with the heat conduction theory,the prediction formula is given,and the thermal insulation performance of insulation board is forecasted,compared the prediction results with the measured thermal conductivity coefficient to confirm the accuracy of model. It has important significance to the research of preliminary structure design,performance prediction and heat conduction mechanism about composite thermal insulated board.
