Tannins are found in most of the species throughout plant kingdom, where their functions to protect against predation and might help regulating growth. There two major groups tannins, i.e., hydrolyzable condensed tannins. The tannins being used as important effective chemicals for tanning animal hides leather processing industry since beginning industry. Additionally, have been using mineral absorption protein precipitation purposes 1960s. These also iron gall ink production, adhesive...
The aim of the present study was to determine influence sulphuric acid hydrolysis and high-pressure homogenization as an effective chemo-mechanical process for isolation quality nanofibrillated cellulose (NFC). cellulosic fiber isolated from oil palm empty fruit bunch (OPEFB) using methods and, subsequently, homogenized a homogenizer produce NFC. structural analysis crystallinity raw extracted were carried out by Fourier transform infrared spectroscopy (FT-IR) X-ray diffraction (XRD)....
This study deals with the fabrication of composite matrix from saw dust (SD) and recycled polyethylene terephthalate (PET) at different ratio (w/w) by flat-pressed method. The wood plastic composites (WPCs) were made a thickness 6 mm after mixing PET in rotary type blender followed flat press process. Physical i.e., density, moisture content (MC), water absorption (WA) swelling (TS), mechanical properties Modulus Elasticity (MOE) Rupture (MOR) assessed as function ratios according to ASTM...
Thermal stability behaviour of coconut coir, banana pseudo stem, pineapple leaf, and sugarcane bagasse fibres was investigated under nitrogen atmosphere.The parameters degradation kinetics were determined by thermogravimetric analysis at heating rates 5, 10, 15, 20, 30, 40 C/min using the Kissinger, Flynn-Wall-Ozawa Friedman model-free methods.Thermal these showed both two three mass loss steps attributed from moisture evaporation to decomposition cellulose, hemicelluloses, lignin as well...
Bilayer hybrid composites fabricated by hand lay-up technique impregnating oil palm empty fruit bunch and jute fibre mats with epoxy resin cured at 100℃ for 1 h followed post curing 105℃. were prepared varying the relative weight fraction of two fibres. The mechanical, morphological thermal properties palm/jute bilayer carried out. When loading is increased in composites, flexural strength modulus will be higher. hybridization fibres composite decreased impact composites. Analysis variance...
In the present study, a successful attempt has been made on enhancing properties of hybrid kenaf/coconut fibers reinforced vinyl ester composites by incorporating nanofillers obtained from coconut shell. Coconut shells were grinded followed 30 h high energy ball milling for production nanoparticles. Particle size analyzer demonstrated that 90% nanoparticles ranged between 15–140 nm. Furthermore, it was observed incorporation shell into composite increased water absorption capacity. Moreover,...
Cellulose nanofibers (CNF) were isolated from Gigantochloa scortechinii bamboo fibers using sulphuric acid hydrolysis. This method was compared with pulping and bleaching process for fiber. Scanning electron microscopy, transmission Fourier transform infrared spectroscopy, X-ray diffraction, thermogravimetric analysis used to determine the properties of CNF. Structural by FT-IR showed that lignin hemicelluloses effectively removed pulp, bleached fibers, It found CNF exhibited uniform smooth...
Oil palm shell (OPS) nanoparticles were utilized as filler in fibers reinforced polyester hybrid composites. The OPS successfully produced from the raw using high-energy ball milling process. Fundamental properties including morphology, crystalline size, and particle size of determined. Tri-layer natural fiber reinforcement (kenaf–coconut–kenaf mat) composites prepared by hand lay-up techniques. influences loading determined analyzing physical, mechanical, morphological, thermal Results...
This paper investigated the upcycling process of thermoplastic waste polystyrene (WPS) into thermosetting particleboard adhesive using two cross-linkers, namely methylene diphenyl diisocyanate (MDI) and maleic anhydride (MA). The WPS was dissolved in an organic co-solvent. weight ratio WPS/co-solvent 1:9, 10% cross-linkers based on solids content were added subsequently at 60 °C under continuous stirring for 30 min. properties, cohesion strength, thermo-mechanical properties WPS-based...
The objective of this study is to determine the effect fiber direction arrangement and layer composition hybrid bamboo laminate boards on physical mechanical properties. raw material used was tali (Gigantochloa apus (J.A. & J.H. Schultes) Kurs) rope in form flat sheets (zephyr) falcata veneer (Paraserianthes falcataria (L) Nielsen). Zephyr arranged three layers using water-based isocyanate polymer (WBPI) with a glue spread rate 300 g/m2. There were variations substitution core veneers...
