“…For comparison, the content of this component in wood is between 40 and 50%, [18] and the percentages are 34% in hazelnut, [19,20] 47% in rice husk and 23% in wheat husk [22]; however, in barley husk and coconut shell, they are 39 and 34%, respectively. [18] The content of hemicelluloses in the fillers used was similar or higher relative to the values mentioned above; the hemicellulose content was clearly greater when compared to rice husk (14%), [22] barley husk (12%) and coconut shell (21%). [18] The content of lignin in the proposed vegetable fillers was rather low, especially in pistachio shell; a comparable value was recorded only in rice husk (14%).…”

“…[21] Another equally significant property of vegetable fillers is the size and shape of the particles, which contributes to the effective transfer of tension from the polymer matrix to the filler. In a study by Gozdecki et al [22], the authors described the effect of the filler size on the tensile and flexural properties of WPC. Both properties increased with the size of the particles.…”

“…Similar relationships were observed when testing other composites. [22,30,31] The stiffness of the composites was estimated based on Young's modulus of elasticity (E t ). Table 2 shows the average values obtained for the given mixtures with respect to the unfilled polymer.…”

The purpose of this work was to obtain environmentally friendly natural fibre composites (NFC) from high-density polyethylene (PE-HD) foil and either finely ground sunflower husk or pistachio shells, which both possess physico-mechanical characteristics similar to wood-polymer composite. The composites were prepared from waste materials without the use of additives. It was found that 66% of the sunflower husk grains were from 180 to 850 μm in size, and 88% of the pistachio shell particles were less than 63 μm in size. With the use of a rolling mixer, six mixtures were produced with filler shares amounting to 5, 15 and 30 wt.% of sunflower husk and 15, 35 and 55% of pistachio shell, from which dumbbell-shaped samples were formed via injection processing. The produced materials were analysed for their mechanical properties (impact strength, hardness, tensile strength, Young's modulus and DMA). The morphologies and chemical composition of the filler as well as the morphological properties of the composites (SEM) were also investigated. The chemical constitution and shape of the filler particles affected the investigated properties of the obtained NFC, and the results were especially significant for the properties of impact strength, stiffness and tensile strength.

“…In related work, Gozdecki et al (2011) studied the effect of particle size and specimen cross-sectional size on the mechanical properties of wood-PE composites. They observed that tensile, flexural and impact strengths increased with increasing particle size, whilst the same properties decreased with increasing specimen cross-section.…”

The purpose of the study was to obtain a composite material with the self-reinforced structure, which processing provide increased mechanical properties. The composites used in presented work were prepared from the two types of fiber mixtures, both were based on polypropylene fibers, the difference was in used cellulose or wood flour filler. Composites were prepared using the hot compaction method. The presented research describes the effect of the composite composition and processing conditions. The results include the static tension measurements, tensile impact tests and thermal analysis, including: DSC and DMTA. The structure has been studies using the SEM observations. Results of presented studies confirm the self-reinforcing effect in obtained hybrid composites. It provides in the comparison to the standard wood polymer composites to the higher level of material reinforcement with lower amount of natural filler.
