摘　　要：为了提升相变复合新材料的力学性能,推动其在居住建筑维护结构中应用。研究了热压温度、热压压力和初始含水率对相变材料拉伸强度、弯曲强度、粗糙度和密度的影响。结果表明,随着热压温度、初始含水率和热压压力的增加,相变复合新材料的拉伸强度和弯曲强度整体表现为先升后降趋势,在热压温度为190℃、热压压力为8 MPa和初始含水率为70%时,相变材料具有最大的拉伸强度和弯曲强度。热压压力、热压温度和初始含水率提高有助于降低粗糙度和峰峰值,并提升相变复合新材料的密度,但是热压温度、初始含水率和热压压力也不能过高,否则会影响致密性并产生压溃,力学性能反而降低。In order to improve the mechanical properties of phase changed new composite material,promote its application in residential building maintenance structures.The effects of hot pressing temperature,hot pressing pressureand initial watercontent on the tensile strength,flexural strength,roughness,and density of phase changed materials were studied.The results showed that with the increase of hot pressing temperature,initial watercontent,and hot pressing pressure,the overall tensile and bending strength of phase changed materials showed a trend of first increasing and then decreasing.When the hot pressing temperature was190℃,a hot pressing pressure was 8 MPa,and an initial watercontent was 70%,phase changed materials hadthe highest tensile and bending strength.The increase in hot pressing pressure,temperature,and initial water content helpedto reduce roughness and peak to peak values,and increased the density of phase changed materials.However,the hot pressing temperature,initial moisture content,and pressure should not be too high,otherwise it wouldaffect the density and cause crushing,and the mechanical properties would actually decrease.
