Abstract To understand the effects of filler-asphalt ratio on different properties of lignin and polyester fiber reinforced shape memory polyurethane (SMPU)/styrene butadiene styrene (SBS) composite modified asphalt mortar (PSAM), as well as to reveal the reinforcing and toughening mechanisms of lignin and polyester fibers on PSAM, SMPU, SBS and mineral powder were first utilized to prepare PSAM. Then the conventional, rheological and anticracking properties of lignin fiber reinforced PSAM (LFAM) and polyester fiber reinforced PSAM (PFAM) at different filler-asphalt ratios were characterized. Test results indicate that the shear strength, deformation resistance and viscosity are increased after adding 0.8wt% lignin fiber or… More > Graphic Abstract

Abstract In this work, solution electrospinning technique was used to produce biodegradable fi bers using a commercially available polyester (Ecofl ex F Blend C1200). These materials (mats) could be of potential interest in tissue engineering. The effect of polymer concentration and the solvent nature on the obtained morphology was related to the wettability of the mat, characterized by water contact angle measurements. According to the results, the electrospun mats presented water contact angles characteristic of hydrophobic surfaces. More >

Abstract Vigorous and continued efforts by researchers and engineers have contributed towards maintaining environmental sustainability through the utilization of waste materials in civil engineering applications as an alternative to natural sources. In this study, granite aggregates in asphaltic mixes were replaced by electric arc furnace (EAF) steel slag aggregates with different proportions to identify the best combination in terms of superior performance. Asphalt mixtures showing the best performance were further reinforced with polyvinyl alcohol (PVA), acrylic, and polyester fibers at the dosages of 0.05%, 0.15%, and 0.3% by weight of the aggregates. The performance tests of this study were resilient modulus,… More >

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 >
