Urea Formaldehyde Composites Reinforced with Sago Fibres Analysis by FTIR, TGA, and DSC

Abstract

Agricultural material or biomaterial plays an important role in the field of fibre-reinforced polymeric materials with their new range of applications and achieves the ecological objective. Composition and structure of the nature fibre and matrix must be taken into consideration for the end use. In this project, Sago fibre particleboard bonds with Urea Formaldehyde to form composite. Fourier Transform Infrared (FTIR) spectra are used to characterize the Sago/Urea Formaldehyde composite in terms of their functional group and bonding. Sago/UF composite with smaller particle and higher loading of fibre with 15 wt% of UF matrix has the higher curing properties. The composite will have a denser structure by adopting bigger particle and higher loading of UF matrix. The Sago/UF composite only endures a single stage of decomposition. Thermal stability results indicate that particle size, particle/matrix interface adhesion, and particle loading have great influence on the thermal properties of the composites.

Synthesis and Characterization of Urea–Formaldehyde Eco-Friendly Composite Based On Natural Fibers

“…The shifting at 2926 cm -1 to 2960 cm -1 for C-H stretching peak suggests that -CH 2 group of the cellulose played significant role in fiber and fiber-matrix interfaces. Similar small peak shifts in FTIR spectra between 1000 cm -1 to 1750 cm -1 represents the weak chemical interaction in filler and matrix (Chiang et al 2015, Zhong et al 2007, Zorba et al 2008.…”

Structures, Properties and Potential Applications of Corncob Residue Modified by Carboxymethylation

“…Natural fibers, such as palm kernel meal, sago fibers, and lignocellulosic waste fibers, have been investigated as fillers to prepare UF resin composite with improved performance [19][20][21]. However, their addition percentage is relatively low and high loading would prevent the effective dispersion in the particleboard [22].…”

Properties of Sago Particleboards Resinated with UF and PF Resin

“…Based on pilot experiment, particles with sieving size 1.18 mm gave the highest internal bonding and screw test of the final particleboard in comparison with several sieves of different sizes utilized during trails [7]. The results had shown that the particles with less than 1.18 mm sieving size have the highest internal bonding and screw test because the particles have better bonding with matrix in the particleboard and had filled up the voids and increased the mechanical strength.…”
