Abstract

Furnace machine or heating furnace is a tool used for heat treatment processes or usually called heat treatment, furnace machines have several types from the beginning found furnace machines, namely induction furnaces/conventional furnaces and then transformed into electric furnaces, electric furnaces are more often used for processes heat treatment because it is cleaner compared to the convection furnace.The furnace machine requires 5000 watts of power, 13.1A. to reach the temperature of 8000 takes 7296 seconds. Furnace machine testing is by quenching using ST-42 steel which is held at 6000 and varying time, the first test material is not treated with heat traetment, for the second test material with a variation of 15 minutes, third 30, fourth 60, fifth 90, sixth 120 minute. the results of the quenching process were tested using the Brinell and Vickers hardness test methods.

Abstract

Making combined materials that consist of unsaturated polyester and coconut fiber is the target of this research. The samples were tested by tensile and hardness tests before and after warm-up, and obtained by the result was that the trend value of hardness of unsaturated polyester+coconut fiber experienced proportional degradation with the addition of the composition of coconut fiber. The composition of 3% coconut fiber+97% unsaturated polyester has the highest hardness value, reaching 46,7 kg/mm2, and downhill becomes 43,1 kgf/mm2 moment heated at a temperature of 500C for 1 hour. Analog to the tensile test, 3% coconut fiber + 97% unsaturated polyester composition has the highest ultimate tensile strength and yield point. Adding fiber can boost the elasticity modulus, but the warm-up treatment causes the expansion of coconut fiber. The result is that the value of the tensile and hardness of the polyblend will go downhill.
