content <strong>of</strong> WF increased. The DT p <strong>of</strong> hybrids with talc was 5–88C lower than<br />
that <strong>of</strong> hybrids without talc. The loading <strong>of</strong> 1 wt% silane to PLA/WF/talc<br />
composites led to a higher thermal decomposition temperature than that <strong>of</strong><br />
3 wt% silane. As WF loading into the PLA increased, the T g <strong>of</strong> the<br />
composites. The addition <strong>of</strong> talc to PLA/WF hybrids also lowered the T g . The<br />
addition <strong>of</strong> WF/talc to neat PLA decreased the T c slightly. The addition <strong>of</strong><br />
1 wt% silane to PLA/WF/talc showed a similar or higher T c compared to that<br />
<strong>of</strong> 3 wt% silane. The application <strong>of</strong> WF, talc, and silane to PLA decreased the<br />
X c <strong>of</strong> composites. The tensile modulus <strong>of</strong> PLA/WF composites was similar or<br />
lower than that <strong>of</strong> neat PLA. The loading <strong>of</strong> talc and 1 wt% silane to<br />
PLA/WF composites improved the tensile modulus. The tensile strength <strong>of</strong><br />
the composites decreased slightly with the addition <strong>of</strong> talc (compared to neat<br />
PLA strength), but it was considerably improved with the use <strong>of</strong> 1 wt% silane.<br />
