Oil-Palm-Fibre Reinforced Phenolformaldehyde Composites

چکیده
Thermophysical properties such as, effective thermal conductivity (A,,) and effective thermal diffusivity (Xc) of untreated reinforced phenol formaldehyde with different weight per centages of oil-palmfibre (x) are measured simultaneously using the transient plane source (TPS) technique between 80 to 120"C. The composites investigated contain 20, 30 and 50 weight per centage of oil-palm-fibre. The experimental results at different weighted composites show that there is variation in A" and Xc in this temperature range. However, a maximum value of A" and Xc is observed at 100"C, which lies in the vicinity of glass transition temperature (Tg) of these composites. Efforts are also made to predict the weight per centage of oil-palm-fibre (OPF) and temperature dependence of A" and Xc through the development of an empirical model. Theoretical predicted values of A" and Xc for these composites are in agreement with experimental results over the entire range of temperature for investigations

Bi-layer hybrid biocomposites were fabricated by hand lay-up technique by reinforcing oil palm empty fruit bunch (EFB) and jute fibre mats with epoxy matrix. Hybrid composites were prepared by varying the relative weight fraction of the two fibres. The physical (void content, density, dimensional stability), and chemical resistant properties of hybrid composites were evaluated. When the jute fi...

Exploring “nano Filler” Based on Oil Palm Ash in Polypropylene Composites
This study presents the utilization of oil palm ash (OPA), a siliceous material from the fiber of oil palm biomass, as a nanofiller for the development of polymer nanocomposites. Polypropylene-based polymer nano-composites reinforced with OPA along with a compatibilizer were prepared by a melt-mixing technique, using a double screw extruder. Variations in the mechanical, morphological, and ther...
متن کاملCoir Fibre Reinforcement and Application in Polymer Composites: A Review
Increasing concern about global warming and depleting petroleum reserves have made scientists to focus more on the use of natural fibres such as bagasse, coir, sisal, jute etc. This has resulted in creation of more awareness about the use of natural fibres based materials mainly composites. In past decade there has been many efforts to develop composites to replace the petroleum and other non d...
