“…Lately, few manufacturers have developed composite insulated panel with fiber reinforced polyester and some of the progress made with the application of these insulated panel appeared to have surpassed metallic reinforced insulated panel [1]. In line with the above, some panels advanced by some authors [6,7] failed to be adapted to moisture related application considering their low stiffness/weight ratio and poor erosion wear. While, the performance of some of these composite reinforced panels continue to receive low patronage in view of their poor fibre-matrix interaction, these particular composite panels developed were specifically reinforced in percent proportion of fiber and the overall heat transfer coefficient of individual specimen was estimated using Eq.…”

Heat infiltration through the external wall of refrigerated vehicles has been a concern to food industries considering high thermal load required to sustain unbroken cold chain. In this research, experiments were carried out with known fibres contents laid out at various orientations and the effect on the heat transfer measured. The results indicate that the estimated overall heat transfer coefficient of the composite reinforced with 10%wt. of fibre at 0o orientation (G10E) offers the lowest U value of 0.386950 W/m2K and 0.196680 W/m2K for 50 mm and 100 mm insulation thicknesses respectively. The effect of fiber orientation in the composite panel in energy saving was to a large extent minimal when compared to the un-oriented composite panel

“…The removal of lignin and moisture in coir pith on chemical treatment makes it much more thermally stable which translates into the thermal stability of the composites containing them. This in fact also results in higher interfacial bonding in the composites thereby making their mechanical property higher than composites with RCP .…”

Thermal stability of composites and their constituents becomes an important criterion during their processing and application in different fields. The present work deals with the thermal stability of coir pith/nylon/epoxy hybrid composites by studying the thermogram, heat deflection temperature, and accelerated ageing of these composites. The effect of chemical treatment of coir pith and hybridization on these properties is dealt in detail in the discussion. The composite samples were prepared by hand layup method followed and by compression molding. Coir pith was subjected to different types of chemical treatments—sodium hydroxide, dicumyl peroxide, acrylic acid, acetic acid, sodium hypochlorite, and sulfuric acid before processing. Thermogravimetric analysis of composite samples showed improved thermal stability with treatment of coir pith and hybridization with nylon fabric. The effect of temperature on the ageing of composites was studied after an accelerated ageing process followed by a comparison of retention in impact strength. The thermogram of the samples was found to complement the results obtained in accelerated ageing and heat deflection analysis. J. VINYL ADDIT.

“…Wu et al studied that self-reinforced PET composite of recycled PET homopolymer filaments serving as the reinforcements and copolymerized PET (mPET) filaments as the matrix exhibit improved resistance to creep deformation [ 17 ]. Composites prepared by hand layup and compression molding of coir pith/nylon/epoxy showed that chemical treatment improves the water resistance and offers optimum retention of impact strength in composites [ 18 ]. Essabir et al developed polypropylene hybrid composites by using coir fibers and coir shell micro-particles under injection molding.…”

In the present work, hybrid composites were developed by using polyester waste fibers along with natural origin materials: olive root fibers and coir pitch filler. Such composite panels can be used as a potential alternative for fiber glass sunshade panels and room dividers in buildings. Hybrid composites were fabricated by mixing polyester waste fibers and olive root fibers in different ratios (0:100, 33:67, 67:33 and 100:0). Coir pith micro-particles with an average size of 312 d.nm were used as filler in the polyester matrix at three different levels (0%, 5%, and 10%) of the overall matrix weight. Mechanical properties, e.g., tensile strength, flexural strength and impact strength, thermal properties, e.g., coefficient of linear thermal expansion, thermo-gravimetric analysis (TGA) and environmental properties, e.g., water absorption, loss of density after exposure to weathering were characterized. For comparison purposes, a commercially available fiber glass sunshades sample was also investigated. Mixture design analysis was used to optimize the ratio of all components in the composite. Graphical comparison of experimental results using regression models showed a high degree of correlation. An optimized formulation of composite with an objective of maximization of tensile strength, flexural strength, impact strength and minimization of water absorption, density loss, as well as coefficient of linear thermal expansion, was determined at 70.83 wt%, 15.15 wt%, and 14.01 wt% of polyester waste fibers, olive root fibers and coir pith micro-fillers, respectively. Overall, it can be concluded that the developed hybrid composites from waste fibrous materials can be used as a promising alternative and a value-added application in buildings and construction purposes.
