Design of experiments; Doehlert method used.<br><p>2 factors (X1: curing time in min; X2: curing temperature in °C); 7 trials; Y: property of the material (response).<br>
Matrix of the trials:<br><b>N</b> - <b>X1</b> - <b>X2</b><br>
1 - 25 - 180<br>
2 - 35 - 180<br>
3 - 15 - 180<br>
4 - 30 - 206<br>
5 - 20 - 206<br>
6 - 30 - 154<br>
7 - 20 - 154<br></p>
Results: estimated response surface (Y estimated for a 95% confidence level) and corresponding polynomial model.
