Investigation of the Influence of Linear Dimensions and Concentration of Carbon and Glass Fibers on the Properties of Polyetherimide

Abstract:

The effect of glass (GF) and carbon (CF) fibers of various linear sizes (0.2 and 3 mm) and concentrations on the properties of polyetherimide (PEI) has been studied. It is shown that the introduction of fibrous fillers leads to a decrease in the melt flow index, and to a greater extent in the case of fibers with a length of 3 mm. Also, it was found that both GF and CF lead to a decrease in toughness and an increase in the elastic-strength properties with a slight advantage of composites containing fibers of a length of 3 mm. In this case, GF composites have significantly higher properties. The study of heat resistance shows a slight decrease for composites with CF and the absence of influence of the filler for composites with HC, regardless of the size of the fibers.
