Abstract

Shape memory epoxy polymer (SMEP) composite specimens with different graphene oxide (GO) contents were manufactured to study the effects of GO mass fractions on epoxy polymer composites. While ensuring the shape memory effect of SMEP, the addition of GO also remarkably strengthened the mechanical performance of the polymers. Analyses of the epoxy polymer composites’ thermal, mechanical, and shape memory performance were conducted through carrying out dynamic mechanical analysis (DMA), thermogravimetric analysis (TGA), and static tensile, three-point bending, impact, and shape memory tests. Moreover, the tensile fracture, bending fracture, and impact fracture interfaces of epoxy resin composites were examined with scanning electron microscopy. The final test results indicated that when the GO content was 0.8 wt %, SMEP composites had good shape memory performance and optimum thermal and mechanical performance.

Summary

Introduce

Epoxy resin is an important type of thermo-responsive resin which has the advantages of good adhesion, excellent mechanical properties, abrasion resistance, and low cost. At present, it plays a very important role in the making of adhesives and in fields such as the construction industry, aerospace industry, electronics industry, and so on. Shape memory polymer composites with thermo-responsive epoxy resin as the matrix can overcome the deficits of low mechanical strength and low deformation recovery of shape memory polymers [4,5,6,7]. Shape memory epoxy polymer (SMEP) has excellent properties It has strong shape memory, which is mainly reflected in the aspects of high shape retention, good shape recovery rate and quick response, and incomparable thermal performance and mechanical performance. The thermal, mechanical, and shape memory properties of epoxy polymer composite the thermal, mechanical, and shape memory properties of epoxy polymer composite specimens with different GO contents were studied by adjusting the contents of the enhanced components
