batches to isolate temperature as the sole variable influencing
mechanical properties. During post-moulding, specimens were
gradually cooled under controlled ambient conditions to minimise
residual stresses and achieve stable, dimensionally accurate test
bars.

The mechanical tests and corresponding apparatus utilized
throughout this experimental study are summarised systematically
in Table 2. Detailed parameters employed for specimen
fabrication are further elaborated in Table 3.
