Summary

The need of novel engineering materials development despite many years of research still remains unmet. Production of polymeric composites with lowered impact on environment moght be realized by incorporation of various sustainable technologies including: valorization of waste materials for production of highly efficient reinforcing fillers, application of renewable and biodegradable natural fibers or polymeric matrices, production of single polymer composites (SPCs) and self reinforcing composites (SRCs) characterized with high recyclability, and many others.
The aim of proposed Special Issue is to share information about recent development of novel polymeric composites based on sustainable technologies and renewable materials, which extend their industrial applications. Furthermore, presentation of various problems, such as: narrow temperature processing window in polymer composites, thermal degradation of waste materials and lignocellulosic fillers during processing or immiscibility/incompatibility of waste materials with polymeric matrix.
High-quality original research articles presenting technological cases, conceptual solutions of new technological and materials insights and reviews in these subjects are warmly welcomed.

  • Effect of Steam Explosion Technology Main Parameters on Moso Bamboo and Poplar Fiber
  • Abstract One of the large-scale industrial applications of Moso bamboo and poplar in China is the production of standardized fiberboard. When making fiberboard, a steam blasting pretreatment without the addition of traditional adhesives has become increasingly popular because of its environmental friendliness and wide applicability. In this study, the steam explosion pretreatment of Moso bamboo and poplar was conducted. The steam explosion pressure and holding time were varied to determine the influence of these factors on fiber quality by investigating the morphology of the fiber, the mass ratio of the unexploded specimen at the end face, the chemical composition, and the… More

  • Prediction and Analysis of Post-Treatment of Sustainable Walnut Shell/Co-PES Parts by Laser Sintering
  • Abstract In order to enhance the strength of sustainable walnut shell/Co-PES (WSPC) sintered parts, wax-filtrated post-treatment was carried out. The effects of treating fluid temperature, preheating time and immersion time on the bending strength of WSPC wax-filtrated parts were analyzed by single factor analysis method. To obtain an accurate model for predicting the bending strength of the WSPC wax-filtrated part, the experiments were involved by using Box-Behnken design (BBD). Main parameters, such as treating fluid temperature, preheating time and immersion time, and their interactive effects were analyzed through analysis of variance (ANOVA) and graphical contours. The results demonstrated that all parameters’… More

  • Experimental Study on Inert Gas-assisted Laser Cut Veneer Based on LOM
  • Abstract Based on the LOM (Laminated Object Manufacturing) process, an inert gas-assisted laser method for wood cutting was proposed. The carbonization degree of wood surface was improved by the introduction of helium (He) gas, and the influence of process parameters on the carbonization layer of wood surface was solved, it was significance to reduce the post-processing of LOM and improve the quality of forming workpiece. The cherry wood veneer was used as the experimental material, under the condition of the same process parameters, the wood was cut with or without inert gas-assisted, and the influence factors of kerf quality were studied… More

  • Decorative Wood Fiber/High-Density Polyethylene Composite with Canvas or Polyester Fabric
  • Abstract Wood-plastic composite is an environmentally friendly material, due to its use of recycled thermoplastics and plant fibers. However, its surface lacks attractive aesthetic qualities. In this paper, a method of decorating wood fiber/ high-density polyethylene (WF/HDPE) without adding adhesive was explored. Canvas or polyester fabrics were selected as the surface decoration materials. The influence of hot-pressing temperature and WF/HDPE ratio on the adhesion was studied. The surface bonding strength, water resistance, and surface color were evaluated, and observation within the infrared spectrum and under scanning electron microscopy was used to analyze the bonding process. The results showed that the fabric… More
