DEVELOPMENT OF CONTINUOUS FILAMENTS FOR FDM PRINT-ING

FJMUGT

Abstract

Polymer composite materials for structural and functional purposes are among the most numerous and diverse types of materials. Their use in various fields of technology provides a significant economic effect compared to traditional units and parts made of metal. The use of filaments with continuous fiber for the manufacture of products from polymer composite materials by FDM printing allows you to create prototypes and scale models in a short time at minimal cost, which corresponds to modern trends in the transition to customized production. Laboratory samples of filaments based on high-density polyethylene and ethylene-vinyl acetate copolymer reinforced with continuous basalt fiber were manufactured. The obtained compositions were analyzed for appearance, geometric size, density, binder content, microstructure, and the number of threads in the basalt fiber. Analysis of the appearance of parts made from polymer composites revealed the presence of minor visible defects (warping, deformation, burns, delamination). The Polyethylene-Basalt Fiber system is suitable for the production of anisotropic composite products for the automotive industry, the production of unmanned aerial vehicles due to its low cost, the availability of a large range of polyethylene brands in the Russian Federation and a domestic manufacturer of basalt fiber.
