Study on mechanical properties of polyurethane mixtures with different fillers combined with industrial problems

Abstract

This paper mainly introduces the classification of polyurethane mixtures. To produce new polyurethane composites used in manufacturing, the team researched Polyurethane combined with different composites and showed the mechanical properties of the composites on a chart. When reducing-graphene oxide (GO) and multi-walled carbon nanotubes are mixed with polyurethane, the composite can increase Young’s Modulus to 615 MPa and tensile strength to 657 MPa with a weight reduction of 5%. Glass fibre filled with Polyurethane also provides a fairly Young’s Modulus (over 10000 MPa) with a high weight percent up to 20%. How to increase the content of reduced GO and carbon nanotubes in polyurethane filling will be a problem worthy of further exploration.
