2.3.5. Impact test
The Charpy impact test was conducted on WPC samples according to ASTM-
D-6110 standard
procedure.
2.3.6. Flexural modulus
A three-point loading test method was applied on WPC samples in according
with
ASTM-D-790M-93.
2.3.7.
Linear burning test
This fire-test was conducted according to ASTM Standard ASTM-D-635-06. The
WPC
specimens
were prepared at a size of 125 ± 5 mm long by 14 ± 0.5 mm wide,
with a minimum thickness of 10 ± 0.5 mm with smooth edges. The specimens were
conditioned at 23 ± 2 C and 50 ± 5% RH for a minimum 48 h; after conditioning, the
specimen was tested within 1 h.
2.3.8. TGA/DSC
The thermogravimetric analysis (TGA) of the palm leave, PVC, PS plastic waste
and
WPC
was carried out in Shmadzu TGA-51 analyzer. Sample weighing
1.1–1.2 mg in mass was heated up to 600 C at a rate of 10 C/min under a continuous
air. The Differential Scanning Calorimetry (DSC) analysis was conducted in
Shmadzu DSC-60A up to 250 C.
