The paper deals with the evaluation of mechanical properties of a biopolymer biodegradable composite obtained by injection molding (InMold technology) of knitted hierarchical fabric in the injection mold. Two methods of modifying natural fibers of the hierarchical fabric were used to influence adhesion at the interface between the polymer and the knitted fabric. The first type of modification was acetylation and the second type was the use of physical treatment using low temperature plasma, atmospheric dielectric barrier discharge (DBD). The polymer composite matrix was PLA polymer from NatureWorks LLC. The structural fabric was a weft interlock knitted fabric in three different geometric characteristics made from natural cotton yarn. Experimental measuring on evaluation of mechanical properties, tensile, flexural and charpy impact tests were performed on prepared samples not only for different types of modifications of natural fibers of knitted fabric, but also in terms of orientation of knitted fabric in a biopolymer composite system. |
