The depletion of log resources encourages research into alternative ways to sustain the wood ***,the 4-year-old Rubber Research Institute of Malaysia(RRIM)clones series,RRIM 2020 and RRIM 2025,were chosen as potential raw materials for particleboard in this *** purpose of this study was to assess the effects of planting density and rubber tree clones on the mechanical and physical properties of single-layer *** planting densities used were low,moderate-low,moderate-high,and high,representing 500,1000,1500,and 2000 trees/ha,*** to manufacturing,the RRIM 2000 series clone trees were harvested,cut,chipped,flaked,and *** mechanical and physical properties were evaluated in accordance with the Japanese Industrial Standard(JIS A 5908-2003).The findings revealed that both planting density and clone had a significant impact on the mechanical and physical properties of particleboard with a thickness of 10 mm and a density of 700 kg/*** 2020 specimens with low planting density had superior modulus of elasticity(MOE),modulus of rupture(MOR),and internal bonding(IB)values of 2415,19,and 1.7 MPa,***,moderate-low planting density demonstrated the lowest thickness swelling(TS)and water absorption(WA)values and was comparable to control particleboard from commercial clone Prang Besar(PB),*** terms of rubber clones,RRIM 2020 particleboard met the minimum requirements of the JIS standard for mechanical properties and outperformed RRIM *** study recommended a low planting density of 500 trees/ha and the RRIM 2020 clone as a suitable raw material for particleboard manufacturing with a ten percent urea formaldehyde resin content.

Effects of Surface Treatments on Tensile, Thermal and Fibre-matrix Bond Strength of Coir and Pineapple Leaf Fibres with Poly Lactic Acid

引用

Journal of Bionic Engineering 2018年第6期15卷 1035-1046页

作者： Ramengmawii Siakeng Mohammad Jawaid Hidayah Ariffin mohd sapuan salit Higher Institution Centre of Excellence Wood and Tropical Fibre (HiCoE) Institute of Tropical Forestry and Forest Products ( INTROP) Universiti Putra Malaysia Serdang 43400 Malaysia Department of Chemical Engineering College of Engineering King Saud University Riyadh 11451 Kingdom of Saudi Arabia Department of Bioprocess Technology Faculty of Biotechnology and Biomoleeular Sciences Universiti Putra Malaysia Serdang 43400 Malaysia Department of Mechanical and Manufacturing Engineering Faculty of Engineering Universiti Putra Malaysia Serdang 43400 Malaysia

Coir Fibres （CF） and Pineapple Leaf Fibres （PALF） are valuable natural fibres which are abundantly available in Malaysia as agricultural wastes. The aim of this study is to investigate the effects of alkali （6%）, silane （2%）, and calcium hydroxide （6%） on tensile, morphological, thermal, and structural properties of CF and PALF to improve their interfacial bonding with Polylactic Acid （PLA） matrix. Scanning electron microscopy and Fourier transform infrared spectroscopy were used to observe the effectiveness of the chemical treat- ments in the removal of impurities. Alkali treated fibres yield the lowest fibre diameter and the highest Interfacial Stress Strength （IFSS）. Thermogravimetric Analysis （TGA） shows improved thermal stability in silane treated CF and alkali treated PALF. It is assumed that fibre treatments can help to develop biodegradable CF and PALF reinforced PLA biocomposites for industrial applications.

Review of Agro Waste Plastic Composites Production

引用

Journal of Minerals and Materials Characterization and Engineering 2013年第5期1卷 271-279页

作者： Hammajam Alhaji Abba Ismarrubie Zahari Nur sapuan mohd salit Department of Mechanical and Manufacturing Engineering Universiti Putra MalaysiaSelangor Malaysia

This article reviews the literature reports base on agro waste plastic composites using different fiber as fillers and reinforcements. Various processing methods and conditions;compression molding process, injection molding, and extrusion method are used in the composites productions. Characterization challenges associated with the agro waste plastic composites productions were also examined. Thus, the findings of this research review can be use as a data base for further inquiring into the agro waste plastic composites in a view to enhance the development of the sector.

2007 5th International Conference on Microwave and Millimeter Wave Technology(ICMMT’2007)

作者： Syarfa Zahirah sapuan mohd Zarar mohd Jenu Center for Electromagnetic Compatibility Kolej Universiti Teknologi Tun Hussein Onn 86400 Parit RajaBatu PahatJohorMalaysia

An enclosure without aperture and wire penetration are impracticable due to the requirement for ventilation and *** paper is written to present the measurement of shielding effectiveness （SE） and S 21 for such enclosure at frequencies below *** measurement results indicate that a wire or cable penetrating into an enclosure has impact to the shielding *** coupling between a wire penetration and a detector inside the enclosure show good agreement between experiment and *** results indicate the same resonant frequency approximately 707.1MHz for a 300 x 120 x 300 mm enclosure.
