Upcoming Conferences Effect of surface treatment on the physical, chemical, and mechanical properties of palm tree leaf stalk fibers Rout, A. The tensile strength of the fibers was improved with an alkali treatment, and the 6 h treatment resulted in the maximum fiber strength.
In this study, nanocomposites based on unsaturated polyester cured by ultra-violet UV radiation were prepared using Kenaf bast fibre and Montmorillonite MMT as reinforcing agent at different percentages.
On the other hand, the percentage of Kenaf fiber in the nanocomposites system also plays a crucial role in determining the nanocamposites properties.
We investigated the effects of amount of antioxidants variability on selected mechanical and physical properties of wood plastic composites.
Recycled high density polyethylene rHDPE and natural fibers were compounded into pellets by compounder, then the pellets were extruded using co-rotating twin-screw extruder and test specimens were prepared by hot and cold press process.
From the study, samples with 0. The effect of antioxidants presence on water uptake is minimal. The fracture surface of the composites was characterized by SEM as well. The results indicated that the composites have higher tensile modulus than that of the pristine epoxy resin.
Quddos, Mohammad Bilal Khan, R. The impregnation of the fiber with a resin system, the polymeric matrix with the interface needs to be properly cured so that the dimensional stability of the matrix and the composite is ensured.
A modified epoxy resin matrix was obtained with a reactive toughening agent and anhydride as a curing agent. The mechanical properties of the modified epoxy matrix and its fiber reinforced composites were investigated systematically. The polymeric matrix possessed many good properties, including high strength, high elongation at break, low viscosity, long pot life at room temperature, and good water resistance.
The special attentions are given to the matrix due to its low out gassing, low water absorption and radiation resistance. In addition, the fiber-reinforced composites showed a high strength conversion ratio of the fiber and good fatigue resistance.
The influences of processing technique such as curing and proper mixing on the mechanical and interfacial properties were determined. The results demonstrated that the modified epoxy resin matrix is very suitable for applications in products fabricated with fiber-reinforced composites.
Berhan, Hanafi Ismail Abstract: Hybrid composites were prepared by incorporating oil palm fruit bunch OPFB fibre in the mixture of clay and polypropylene as secondary filler.
Tensile and impact tests were performed on the hybrid composites to evaluate their mechanical performances. Water absorption and thermal degradation tests were also conducted on the hybrid composites.HTPB being chemically inert with Novolac, was blended with Resole.
80/20 blend of Novolac and Resole was selected for toughness improvement studies taking in to account the blend's processability and glass transition metin2sell.com blend was modified with in different weight fractions of .

This study performed to investigate the effect of addition of 0, 0 1 Diallyl Bisphenol A (DABA) on the thermal, mechanical, morphological and flame retardance behaviour of Novolac Phenolic/Carbon fibre composites.
The miscibility of DABA and novolac phenolic resin was studied using DSC. Both modified and unmodified novolac phenolic resin were characterised for chemical structure using FTIR.
