摘要
制备了聚氨酯弹性体/环氧复合板;研究了环境温度对复合板的拉伸、弯曲力学性能的影响。结果表明:复合板的扯断力、弯折力及聚氨酯弹性体的拉伸性能随环境温度的升高先下降再上升,断口处的粘接状态对复合板的弯折力影响显著。
The polyurethane/epoxy composite plates were prepared. The effects of environmental temperature on tensile, bending mechanical properties of the composite plate were researched. Results showed that the tensile and bending force of composite plate, tensile property of polyurethane elastomer decreased and then increased as the environmental temperature increased. The bending force of composite plate was significantly affected by the adhesive state on fracture.
