Glass fiber/wood flour modified high density polyethylene composites

Abstract

Composites of high density polyethylene (HDPE) with the reinforcements of glass fiber (GF) and wood flour (WF) have been studied in this work. High-density polyethylene-grafted maleic hydride (HDPE-g-MAH) was used as a compatibilizer. In particular, the effect of GF, WF, and HDPE-g-MAH on the overall properties of GF/WF/HDPE composites (GWPCs in short form) was systematically studied. The results indicate that HDPE-g-MAH as a compatibilizer can effectively promote the interfacial adhesion between GF/WF and HDPE. By the incorporations of GF/WF, the heat deflection temperature can reach above 120 C, and the water absorption can be below 0.7%, also the tensile strength, flexural strength, and impact strength of GWPCs can surpass 55.2 Mpa, 69.4 Mpa, and 11.1 KJ/m 2 , respectively.

Effects of hybridization and interface modification on mechanical properties of wood flour/polymer composites reinforced by glass fibers

“…Both of them reduced the energy absorption capability of the composites during fracture. The parallel results were reported in the previous study where the authors claimed that more fillers loading could cause agglomeration, resulting in decreased mechanical properties of hybrid composites .…”

Utilization of renewable filler from lichen in low density polyethylene

“…Melt flow index values increased from 2 g 10 min 21 for neat polyethylene to 2.2 g 10 min 21 , indicating a decrease in processability as seen in Table 5. Meanwhile, a decrease in MFI values can be observed with an increase in filler amount and processability became more feasible [33].…”

“…These types of fillers have been processed with polyethylene, polypropylene, PVC and ABS systems in which processing temperatures are lower than their degradation temperatures [8]. Among those studies performed with wood flour were more popular due to its environmentally benign character [9][10][11][12][13][14][15][16][17][18][19][20][21].…”

“…Prior to DSC recording, samples were heated to 2508C then cooled at a rate of 108C min21 to 2308C in order to erase the influence of any previous thermal histories. Samples were subsequently heated from 230 to 2508C at a heating rate of 108C min21 . The melting temperature (T m ) and the heat of melting (H m ) were measured in the second scan.…”

Thermal Decomposition Kinetics of Basalt Fiber-Reinforced Wood Polymer Composites

“…Over the past few years, wood-plastic composites (WPCs), which show advantages with respect to biodegradability, low cost, superb mechanical and thermal insulation performance, and availability, have been regarded as a novel green renewable material exhibiting great potential for structural building applications [ 1 , 2 , 3 , 4 ]. However, the increasing environmental concerns and market demands on natural fibers mean that reinforced polymer matrices in WPCs must be more environmentally friendly, cost-effective, and higher strength [ 5 ].…”
