The Izod impact test was conducted by using an Izod impact tester (Yasuda Impact
Tester) according to ASTM D 256-06. The dimensions of the WPCs were
12.7 mm 64 mm 6 mm with a 45 angle V-notch and 2.5 mm in vertical depth.
A drop-weight impact test was also performed on the recycled WPC specimens having
dimensions of 1500 mm 1000 mm 6 mm. The impactor was a cylinder of
12 mm diameter and 300 mm in length, its weight was 1 kg. The specimen was
fixed on supporting floor which had a cutout hole of 20 mm in diameter. The
drop-weight impact test was carried out at room temperature by using an instrumented
drop-weight impact testing according to ASTM D 4226-00. The impact energy
reported was the average of 20 tested recycled WPC samples.
