The Impact

The influences of Carbon Black (CB) as filler for rubber toughened polyester composite on thermal properties were investigated, in consideration for applications such as automotive parts and integrated circuits (IC) encapsulations. The usage of CB as filler is one of the efforts in increasing and varying the use of rubber and unsaturated polyester thermoset in composite materials. Unsaturated polyester was mixed with 3% liquid natural rubber (LNR) as toughening agent and CB, which were varied from 0, 2, 4, 6, 8, and 10% using mechanical stirrer and moulded by using the open mould technique. Impact testing was conducted for mechanical property and it was found that the addition of CB increased the impact strength by 87%. Thermal properties of the composites were evaluated using a thermogravimetric analyzer (TGA) and differential scanning calorimetry (DSC). The TGA curves of the composites were quite similar, but there were slight increment in thermal stability for several CB filled composites compared to the neat polyester matrix. DSC analysis showed that all the composites were fully cured, and CB filled composites had a slower heat flow rate compared to the neat rubber toughened composite.

Polyester Composite

Sand reinforced polyester composite have been prepared by compression molding method with a variety of range (0,15,30,45 60%) sand respect to the unsaturated polyester resin. various parameter like mechanical, Physical and thermal properties of sand reinforced, polyester resin composite have been determined by various technique like water compressive strength ,flexural strength , hardness and thermal analysis. Physical properties like density and water intake increases with the addition of sand ,compressive strength increases but flexure strength decreases with the amount of sand, on hardness test, Vickers hardness increases but on leeb rebound it decreases with amount of sand, and finally thermal conductivity decreases with the addition of sand.

AbstractThis research was carried out to evaluate the effect of oil palm ash (OPA) on the mechanical and thermal properties of biocomposites. Different compositions of OPA (i.e. 0, 10, 20 and 30 vol%) were introduced to unsaturated polyester (UPE) by using simple casting method with methyl ethyl ketone peroxide (MEKP) as a hardener. The specimens were prepared based on ASTM D5083 standards for tensile testing. From the results, it was found that the mechanical properties of UPE/OPA composites were improved in modulus with increasing the OPA content. The physical properties of UPE/OPA were also investigated where the density of biocomposites decrease with increasing OPA while the water absorption of UPE/OPA increase with increasing OPA. The thermal and morphological characterization of the UPE/OPA composites have been done using TGA, DSC and SEM.
