DEVELOPMENT OF TECHNOLOGIES FOR OBTAINING COMPOSITE MATERIALS BASED ON THE USE OF OILSEED FLAX FIBERS _2021

Abstract

The article examines the ways to solve the problem of developing a scientific basis for obtaining composite materials of different functional purposes from oilseed flax fibers. The paper covers theoretical and experimental research in the area of processing flax raw materials. The purpose of the study is to provide scientific substantiation of developing the technologies for obtaining fillers to reinforce composite materials. In order to do it, modification of oilseed flax fiber was performed and a technology for processing oilseed flax straw with regulated technological and performance characteristics was developed. The article also presents the results of the research on determining causes of low wettability of oilseed flax bast. In order to find out the causes of low bast wettability, research on examining chemical composition and anatomy of straw stems was conducted. The formulation for preparing the fiber aimed to be used as a filler for reinforcement of composite materials is offered. The study suggests evaluation of the quality of composite materials produced based on using modified oilseed flax fibers.
