Three polymeric blends were prepared using epoxy, nitrile butadiene rubber (NBR), and polyurethanes (PU) to develop antiskid surfaces with the required mechanical properties. The optimum mixing ratio was decided according to the results of the coefficient of friction and impact tests. Mechanical properties, including wear, bending, compression, imp...

This study involves the preparation of polymer matrix composite by the hand lay-up process, using unsaturated polyester resin (UPR) as a matrix and waste aluminum flakes as reinforcement material in different weight fractions (0, 10, 30, 40 and 50%) wt. of aluminum. All samples were subjected to bending, tensile, hardness tests and the scanning ele...

In this article, the influence of infill ratio and infill pattern on the compressive strength and hardness of 3D printed polylactic acid (PLA) based polymer are studied. The fused deposition modelling (FDM) technique was used to produce the 3D-printed samples. In the current work, three specimens of each type have been tested with selected infill r...
