Effect of Environmental Temperature on Mechanical Properties of Polyurethane/Epoxy Composite Plate

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.
