Abstract Fiber length and distribution play important roles in the processing mechanical performance of fiber‐based products such as paper fiberboard. In case wood–plastic composites (WPC), production WPC with long fibers has been neglected, because they are difficult to handle current equipment. This study provides a better understanding effect fiber on properties. The objectives this were therefore determine role formation process property development WPC. Three chemithermomechanical pulps...
Abstract This study assessed the potential of wood residues as fiber sources for wood-plastic composites (WPC) and examined impact intrinsic properties on strength development. Sawmill sawdust, underused species, bark, composite panel, pulp paper sludge were sampled. Fibers characterized cellulose content, ash aspect ratio. WPC samples formed by twin-screw extrusion compounding, followed injection molding at three proportions. mechanical properties, water uptake, swelling increased with...
This study investigated the morphology, tensile properties, thermal conductivity, and stability of short carbon fiber reinforced polypropylene (CF/PP) composites. CF/PP composites were prepared with varying amounts (9, 15, 20, 25, 30 wt%) in PP matrix without maleic anhydride grafting as a coupling agent. Samples by extrusion blending followed injection molding. Results showed that addition CFs significantly improved modulus strength 455% 168%, respectively, at wt% loading compared pure PP....
The preparation of bio-composites based on engineering plastic is always restricted by the low thermal stability lignocellulose. In this study, lignocellulose was improved boric acid modification. Then, borated characterized to analyze mechanism involved in improvement stability. Furthermore, untreated and combined with polyamide 6 produce bio-composites. effects content modification color, mechanical properties resulting composites were compared analyzed. Boric protected from degradation,...
Abstract Mercury intrusion porosimetry (MIP) was used to evaluate the impregnation mechanisms of wood by methyl methacrylate (MMA) through examining changes in porosity, pore volume, size distribution and bulk density solid before after MMA impregnation. Porosities MMA-impregnated (hardened) samples were lower than those for six studied species, five hardwoods one softwood. Densities hardened enhanced from 45 130% depending on species. The volume available mercury shifted d>0.1 µm d≤0.1...
This study aimed to develop new biobased materials containing plasticized cellulose acetate (CA) by Fused Filament Fabrication (FFF). We investigated the influence of CA on viscoelastic/dielectric properties and 3D printing dielectric polymer blends. A microstructural analysis showed that blends had a strong heterogeneous morphology, as two phases formed fibrillar lamellar structure. strongly increased blend viscosity at 175 °C, multiplying 100 times complex between neat PLA 40% weight...
In the wood panel industry, metallic contaminants raise significant concerns, especially regarding press plate's surface integrity, which requires a thorough inspection. This study investigated effect of on plate damage and evaluated use infrared thermography (IRT) (IR) spectroscopy as non-destructive testing (NDT) methods for detecting these in manufacturing. Metallic embedded within lab-scale panels demonstrated their impact quality both resulting panels. Moreover, confocal laser...
