Thermal and Dimensional Stability of Injection-Molded Sisal-Glass Fiber Hybrid PP Biocomposites

This article reports on the thermal and dimensional stability of sisal-glass fiber hybrid biocomposites with 30% fiber (wt%) reinforcement in polypropylene (PP) matrix. Hybrid-fiber effect on thermal properties such as specific heat (Cp), melting and crystallization behavior, thermal degradation and dimensional properties such as water absorption and volumetric coefficient of thermal expansion (CTE) was studied. Hybrid biocomposites showed a …
