Abstract

This paper presents the results of experimental investigations into the effects of raw material composition and properties on water absorption in hay-plastic composites. It is possible to identify important parameters of the raw materials used in HPCs production such as the size of the hay sawdust particles, hay/plastic ratio, and type or plastic matrix. The goal of this research was to produce HPCs with acceptable and comparable quality. This is determined by the final mechanical properties. The particle size of the hay sawdust used to produce HPC has a significant impact on the mechanical properties of composites as well as other important properties like water absorption, hardness and frost resistance. This paper examines the relationship and impact of the input haysawdust particle sizes, hay/plastic ratio, and water absorption on composites. The authors also intend to explore the potential for waste materials usage. These experimental research results were made using a semi-operational molding press, where injection is done by a screw. Meadow hay, HDPE resin matrix, and recycled HDPE were used as input materials. The lids made from PET bottles served as the containers. Based on a combination of default levels of hay/HDPE concentration and using recycled HDPE rather than virgin HDPE, the effect of hay sawdust particles on water absorption was determined
