I have checked thermal insulation properties FRP (Fiber Reinforced Plastic). We are making one dryer in FRP that’s why I need to test this property.
I get one close box of FRP and filled it with boiled water at 67′ C. This box is fully air tightened with rubber mat, with no leakages.
I started this experiment. I checked last reading at 9:12 AM morning the temperature was 33’C and constant onward.
