“…The implementation of green technology especially on developing new material product will be an option to the industry and also the government in driving new economic growth by contributing to fiscal consolidation, enhancing productivity through greater efficiency in the use of natural and reusable resources [1][2][3][4]. Green technology product development, sustainability, cradle to cradle design and its viability are the major issues of this technology, whereby the product development can last indefinitely into the future without damaging or depleting natural resources, hence it can be fully reclaimed or reused [5][6][7][8].…”

Abstract-The fabrication of single square patch antenna for proposed Leucaena Leucocephala ("Petai Belalang") Wood Plastic Composite (WPC) substrate board (PB Substrate board) and FR4 substrate board is presented in this paper. The experiment objective is to measure the performance of an antenna fabricated on the FR4 and PB substrate (proposed substrate) by comparing the performance in terms of material's dielectric constant and electron mobility and antennas' loss tangent, return loss (S 11 ), radiation pattern and practical antenna transmitting performance. The new substrate compositions of Leucaena Leucocephala stem and polypropylene (PP) are 30% and 70% consecutively. The result for 150 µm (sample B) indicates stability on most dielectric constant (ε r = 3.02), loss tangent (tan δ = 0.029) and electron mobility (5.31 × 10 3 cm 2 /V s ), with the consistency of antenna result, between simulation and measurement. All results obtained will be analyzed and displayed in the form of data and graphs.

“…Some authors claim that acetylation improves the mechanical and thermal properties of WPCs (Tserki et al 2006;Lisperguer et al 2007;Abdul Khalil et al 2007;Özmen et al 2013). In contradiction to these studies, it was also reported that acetylation reduces the mechanical properties of WPCs (Luz et al 2008;Mat Taib et al 2010).…”

In order to compare the effect of vinyl acetate modification (VA) at different levels of weight percentage gain, Scots pine wood flour was modified with VA to three different wt% gains (10%, 16%, and 21% WPGs). Acetic anhydride (AA) modification at 24% WPG was also studied. Modified Scots pine wood flour reinforced HDPE composites (WPCs) were produced at 30 wt% wood flour loading by using extrusioninjection molding process and the mechanical properties of WPCs were determined. The thermal and morphological properties of WPG were characterised by using TGA and SEM techniques. The increase in tensile strength was significant for VA modified WPCs in comparison to the AA modified, unmodified or neat HDPE composites. Thermal stability was also significantly improved with increasing the WPG levels of VA modification.

“…In recent years, the various lignocellulosics fibers such as flax, hemp, kenaf, corn stalks are attempted to use instead of wood flour as a substitute material in WPC. WPC can be produced by using various amounts of wood flour loading (about 50% or above) [3,5,[6][7][8][9][10][11].…”

The objective of this study was to evaluate the replacement of wood flour by Turkish pine bark residues for production of wood plastic composites. High density polyethylene was chosen as matrix and seven different compositions were used for production of composites. In order to compare the effect of bark residues flour as a filler, bark residues-HDPE composites were produced with various wt% bark residues loading (10, 20, 30 and 40 wt%). Bark residues filled HDPE pellets were produced by using a twin-screw extruder, then 25 cm (l) x 25 cm (w) and 2 mm (t) composites were produced with compression molding technique according to ASTM D4703-10. For each composition, three composites were produced. Tensile and flexural tests were performed with a Universal Testing machine. Impact strength was measured with a Zwick HIT5.5P Impact Testing machine. Tensile and impact strength of the composites decreased with increasing bark flour loading whereas bending strength and modulus of eleasticity values were improved with addition of the bark flour. All produced bark flour filled composites showed better modulus of elasticity and bending strength properties than ASTM D6662-13 standard requirements for polyolefinbased plastic lumber. Morphological properties of bark residues-HDPE composites were characterized by scanning electron microscopy (SEM) technique.
