FIBRE COMPOSITE MATERIALS MECHANICAL PROPERTIES OF POLYMER COMPOSITES REINFORCED WITH KNIT FABRICS MADE OF HIGH-STRENGTH ARAMID FIBRES

摘要

The possibility of manufacturing knitted fabrics with different properties for reinforcing polymer composites was demonstrated. In making composite materials based on knits, structurally balanced weaves of the 1 + 1 rib and Milan rib type are preferred, since traditional methods of wet heat treatment are unacceptable for knits made of aramid fibres, and for this reason preventing twisting of the fabric is extremely important. The studies showed that the mechanical properties of knit polymer composites are a function of the structure of the knit fabrics to a significant degree and can vary significantly within a wide range.
