Abstract—In this study, design experimental by two-level
Factorial design to screen the factors to those factors that affect
the ablation rate significantly. The following parameters were
varied: amount of phenolic curing temperature and curing time.
Factors that affect the ablation rate are as follows curing time,
amount of phenolic resin, interaction between curing
temperature and curing time, interaction between curing time
and amount of phenolic resin, interaction between curing
temperature and amount of phenolic resin and 3-way
interaction of amount of phenolic resin, curing temperature and
curing time. As the results of main effects analysis to determine
0.75 wt.% of phenolic resin, curing temperature 160 °C and
curing time 35 min to give the ablation rate was 0.121 mm/s less
than 0.14 mm/s according MIL-l-24768 standard.
Index Terms—Phenolic resin, ablation rate, rocket motor,
insulation.
