In this research, extracellular polymeric substances (EPS), such as EPSflocs and EPSgranules, were successfully extracted from activated aerobic granular sludge, respectively, tested bio-based flame retardant materials. Flax fabric was coated by the biopolymeric its flammability evaluated based on a vertical burning test defined in US Federal Aviation Regulation. Both EPSgranules flax fabrics achieved self-extinguishment due to effective char formation. particular, result of sample met...
The main goal of this study is to obtain a morphological confirmation the contribution coalescence fibril formation mechanism in microfibril reinforced composites (MFC) and way explain large differences sizes starting spheres resulting long microfibrils, at rather modest draw ratios (between 6 12). For purpose, peculiar property compatibilizers has been exploited, namely coating dispersed particles thus preventing them from eventual coalescing after coming contact. Using scanning electron...
Four biomass wastes (rice husk, coffee coarse wool, and landfill wood) were added with biochar polypropylene (PP) to manufacture biocomposites. Individual biomasses tested for their combustion behavior using cone calorimeter. Biocomposites analyzed fire/thermal, mechanical, morphological properties. Wood had the most desirable comprehensive effect on both mechanical fire properties of composites. In particular, wood composite exhibited highest values tensile/flexural a relatively low peak...
Abstract This article describes an experimental investigation on end milling of glass fiber reinforced polymer (GFRP) composites using uncoated tungsten carbide tool. A series experiments were carried out to evaluate the machinability GFRP in terms tool wear, useful life, machining quality, and forces. Machinability data evaluated form Taylor's equation order predict performance while this composite material. The life cutting was found be well described by equations. speed identified as key...
This study evaluates the influence of hybridization on flammability, thermal, dynamic mechanical and impact properties bamboo–glass hybrid polypropylene composites. Flammability tests using cone calorimetry show that composites performed better than glass–polypropylene (GPP) composites, exhibiting a minimum reduction 19% heat release rate (HRR) smoke as well taking longer to ignite. Thermogravimetric analysis (TGA) reveals are thermally more stable before starting degrade at 275°C fully...
Abstract For many applications, the perceived quality of a medium-density fibreboard (MDF) is influenced by appearance its machined surface. The behaviour MDF has been studied passing cutting tool through it at relatively low speed. A digital camera was used that travels synchronously with and deformation occurring in front tip recorded. magnification approximately 30× also allows individual fibres or bundles to be clearly observed. Photographic images have taken same machining process much...
To minimize the surface roughness and delamination problems during end milling of natural fiber reinforced composites (NFRCs), it is essential to understand effects machining parameters (spindle speed feed rate) kinematics material removal. In this study, on machined quality – (Ra) factor (Fd), kenaf, jute rice husk (RH) polypropylene (PP) has been analyzed using a two-factor, three-level experimental plan. It noticed that there are significant differences in silicon contents (kenaf: 0.57%,...
Graphene nano-platelets (GNPs) can substantially improve the performance of epoxy resin, but improving effects are highly dependent on GNP dispersion uniformity in matrix.The aim current study is to explore influence matrix viscosity GNPs.Thus, with three disparate viscosities was reinforced GNPs varying from 0 3 wt%, and thus properties composites were identified.Significant differences rheological electrical percolation thresholds found a change viscosity.The lowest threshold (0.3 vol%)...
