| Summary: | Composites of sugarcane bagasse in poly(vinyl chloride) (PVC) matrix
were produced by a compression molding method followed by various heat
treatment processes, involving slow cooling (annealing), fast cooling (quenching),
and re-heating to a temperature below Tg. The effects of the thermal history were
examined by the measurement of tensile strength and elongation at break as well as
by differential scanning calorimetry. It was observed that the heat treatments
affected the elongation at break of unfilled PVC significantly with less significant
effect on the tensile strengths. In contrast, various tensile strengths of sugarcane
bagasse PVC composites were observed after various heat treatments with less
significant effect to the elongations at break. In addition, recycling of the composites
may erase the effect of thermal history. Uniform tensile properties of the composites
were achieved after recycling process. |
