“…In its areas, if we examine the DTG spectrum, we observe a peak with a maximum noted at approximately 464°C, 480°C, and 500°C, respectively for biocomposites containing 25%, 35%, 45% by mass of powder. These results obtained are confirmed by other research works [23,24].…”

Biocomposites based on polypropylene (PP) and typha fibre were prepared using a twin-screw extruder and different characterisation techniques, namely thermal, mechanical, rheological and morphological analysis, to evaluate the effects of typha stem powder on the final properties of the biomaterials. The rheological characterisation showed that the G' and G" values of pure PP and biocomposites increase with the rate of reinforcement and are related to agglomeration phenomena of Typha fibres which reduce the sliding or flow between them inside the biocomposite. The viscosity of the composites is strongly influenced by the shear rate. Shear thinning behaviour of the melt was observed. The results of the mechanical tests show an increase in tensile young's modulus up to 45% and an increase in tensile strength up to a critical value of 25% for typha stems, which can be attributed to the good interfacial adhesion between the matrix and the filler. Differential Scanning Calorimetry (DSC) measurements indicate the presence of crystalline phases and a slight difference of about 3°C between the melting temperatures. Typha acts as a nucleating agent. Micrographs show the diffuse aspect of the fibre distribution in the matrix. The good wettability of typha fibres by polypropylene contributes to the reduction of microcavities, which has a positive effect on the mechanical properties up to a certain level of reinforcement. Finally, the thermogravimetric analysis shows that typha fibre decreases the thermal stability of the biomaterials.

“…Rabe et al [18] applied methanol solution, acetylation, and heat treatment to the wood and compared it with the untreated wood, the treated wood had better flame retardant performance. Suoware et al [19] studied the sawdust fire response of material, using a universal testing machine, TGA, and cone calorimeter. The tensile properties of materials that added different flame retardant properties were tested in addition to the bending properties and thermal stability, the results indicate that added impurity-free flame retardant material will improve the tensile properties, flexural properties, and fire performance.…”

Fire safety of ancient wooden buildings is one of the most important issues in the world. In this paper, partition boards with different thicknesses from 15 to 25 mm were heated by a 15-cm-diameter pool fire and a methane Bunsen burner. The temperatures and the carbonization rate of partition boards were measured and analyzed. The results show that when a pool fire was used to heat the wood sample at a distance of 30 cm, two flames appear on the sample surface. When a Bunsen burner heats the sample, the sample is burned until the center point is burned through. The thickness of the sample is increased by 5 mm, and the acceleration time of the temperature rise rate at the center is doubled. Under the condition of a pool fire, the thickness of the sample is increased by 5 mm, and the average carbonization rate at the center point is reduced by 40%. Under the condition of Bunsen burner, the average carbonization rate of the center point decreases exponentially when the thickness of the sample increases by 5 mm. In the case of the same fire source, the carbonization rate of the samples with different thicknesses has the same change trend in the horizontal and vertical directions. Compared with the pool fire, the burn-through time of the center point of the sample is reduced in the case of the Bunsen burner for a sample of the same thickness, and the average carbonization rate of each measuring point increases.

“…As some of the mechanical properties of WPCs, such as strength and stiffness, are lower than those of solid wood (Sain and Pervaiz, 2008), they are most commonly used in applications that do not require good structural performance. WPCs are commonly used in building materials, such as decking boards (Bolin and Smith, 2011;Sun et al, 2017) and panels (Suoware et al, 2019), and automotive components (Ashori, 2008). Apart from these, some more specific uses have been identified and tested for WPCs.…”

The European Commission's ambitious construction and demolition waste (CDW) material recovery target has placed pressure on Finland to increase its CDW material recovery rate. It has been identified that using CDW fractions, e.g. waste wood, plastic, mineral wool and plasterboard, as raw materials for wood polymer composites (WPCs) may help in reaching the CDW material recovery target. The objectives of this study were to assess the environmental impacts of WPC production using specific CDW fractions, namely wood, plastic, plasterboard and mineral wool, as raw materials, and to compare these impacts with the baseline situation where these CDW fractions are treated with conventional waste treatment methods such as landfilling and incineration. The study focused primarily on the depletion of fossil hydrocarbons and climate change. The results indicate that, when compared to the baseline situation, the environmental impacts of CDW management can be decreased when CDW fractions are used in WPC production. By substituting WPCs for plastic or aluminium, considerable environmental benefits can be achieved in terms of the aforementioned impact categories. Due to the differences in the physical and mechanical properties of WPCs compared to plastic and aluminium, WPCs cannot necessarily substitute them in a mass-based ratio of 1:1. This was acknowledged in the study by identifying minimum substitution rates for different materials. For instance, the produced WPCs should substitute at least 6% of plastic and 8% of aluminium in order to decrease the impact on climate change compared to the advanced waste management scenario. Therefore, in applications where WPCs can be used as a substitute for these materials, WPC product design and development should be prioritised.
