Effect of marble powder concentration on Mechanical Properties of unsaturated polyster resin for the development of rock climbing holds

Abstract

Abstract-The introduction of climbing holds has given rise to indoor climbing facilities. Climbing holds arranged in the form of a route are used to simulate an artificial environment for rock climbing, often similar to that found in nature. This paper highlights the significance of material composition for the application of rock climbing hold manufacture. A particle reinforced composite material, comprising an unsaturated polyester resin, reinforced with marble powder was developed and the effect on mechanical properties was studied with varying powder concentration, beginning from 0% reinforcement to 30%, 40%, 50% and subsequently 60 % reinforcement. Test specimens were made according to ASTM standards and were tested for tensile, Izod impact strength and Rockwell hardness. Trends were established based on the results obtained. Furthermore, hardness values were also compared with commercially available climbing holds.

Application of Mathematical and Experimental Approach in Description of Sedimentation of Powder Fillers in Epoxy Resin

“…Most engineering PMCs are fiber-reinforced polymer (FRP) [9][10][11], but also polymer concrete [12][13][14] or cast polymers [15][16][17], also known as synthetic cast products. Cast polymers also have a wide range of applications, e.g., cultured marble, cultured onyx or cultured granite used for sinks or pools applications [18,19], or engineered stone for climbing handles [20].…”
