“…In the earlier work of Durowaye et al (2017), unreinforced polyester resin sample exhibited flexural strength of 35.42 MPa which is low when compared with that of crab shell and charcoal reinforced samples. This clearly shows the effect of reinforcement on the flexural strength of the samples.…”

“…The decrease in the modulus of elasticity could be due to agglomeration of the particulates as earlier reported. In the earlier work of Durowaye et al, (2017), unreinforced polyester resin sample exhibited modulus of elasticity of 1000 MPa. This is higher than that of the reinforced samples.…”

Composites are produced when two or more materials are used to give combination of properties that cannot be attained otherwise. This study aims to use crab shell and charcoal reinforcements to enhance the mechanical properties of polyester composites and decrease the environmental pollution caused by the agro waste. In this study, 5 – 25 wt. % of 100 g of grounded charcoal and crab shell with an average particles size of 150 µm were used for polyester matrix composites. Flexural strength, impact resistance, hardness and elastic modulus tests were carried out on the developed samples. The microstructure of the samples revealed a uniform distribution of the reinforcements within the polymer matrix with different morphology of the biocomposites. The results showed that the greatest flexural strength value of 361.37 MPa was obtained at 25 wt. % and the highest Brinell hardness number (BHN) was 118.27 at 20 wt. %. However, the highest modulus of elasticity was 335.63 MPa at 15 wt. % reinforcement with crab shell reinforced and was 308.64 MPa with charcoal reinforcements at 20 wt. %. Furthermore, the highest impact energy was 5.49 J for crab shell and 5.31 J for charcoal reinforced polyester composite. The development of the biocomposites of these materials will decrease the environmental pollution and improve the properties of the polyester matrix composites for engineering applications.

“…In another group of studies on developing alternative application areas for Al‐dross, Al‐dross‐filled polymer composites are prepared by using different polymers such as epoxy, [ 17 ] polypropylene, [ 18 ] and nylon. [ 19 ] In one of these studies, Adeosun et al prepared PP/Al‐dross composites by adding Al‐dross into the PP phase by 2–50% wt. [ 20 ] The authors reported that the ultimate tensile strength of PP improved by 68% (at 15% wt.…”

In this study, different amounts of aluminum dross (Al‐dross) powders were incorporated into polyoxymethylene (POM) by the melt‐mixing method, and morphological, thermal, rheological, mechanical and dielectric properties of the obtained composite samples were investigated. So, it was aimed to develop value‐added products and create an alternative utilization method for industrial waste that poses environmental risk and does not have a useful application area. The morphological analyses performed by scanning electron microscopy (SEM) showed that the Al‐dross contained various inorganic components with different particle sizes such as Al2O3, NaCl. Moreover, no significant structural incompatibility between the POM and Al‐dross was observed. In contrast, the SEM analyses showed non‐coated filler particle surfaces, which were probably due to the breaking of NaCl particles during the extrusion process. In the differential scanning calorimetry (DSC) analysis, it was found that the effect of Al‐dross addition on the crystallization temperature, amount of crystalline structure in the polymer phase or crystallization rate was limited. The rheological analyses showed that the Al‐dross particles formed rheological percolated structures at an Al‐dross ratio of 20% wt. In the dynamic mechanic analysis (DMA), it was observed that the modulus of elasticity (E') increased by approximately 40% and creep strain decreased by approximately 50% by the addition of Al‐dross into the POM phase at the 40% in %wt. Finally, in the dielectric analyses carried out in the frequency range of 1–14 GHz by a vector network analyzer, it was concluded that incorporating Al‐dross at 40% caused an increase of 1.5 and 3 times in real and imaginary part of the complex permittivity.
