“…The synergic effects of particle stiffness and ductility enhanced the flexural strength and modulus of the composites. Similar explanation has been made by [8]. The strengthening of the developed polymeric composites due to particle addition to the matrix is ascribed to craze formation during the flexural loading at the bending region.…”

“…Polymers are soft, light and resistant to chemical attack but their low mechanical properties limit their applications in engineering structures [6]. In developing polymeric composites, attempt to improve mechanical properties of polymers; conventional aramid, glass, carbon and natural bamboo, coconut, palm kernel, bagasse fibres have been used [7,8]. Among polymers is epoxy resin which has a good thermal stability, low shrinkage on curing and has been used as a matrix for developing high performance composites for engineering applications [9].…”

Polymers are characterised with lightness, ease of formability and resistance to chemical attack but their modulus and strength are low. Epoxy was reinforced with aluminium particles of different sizes. Bond, functional group and chemical formulae of the composite phases were examined using Fourier Transform Infrared Spectroscopy (FTIR) and X-ray diffractometer. The flexural test was also conducted on the developed composites via three-point method. Analysis of variance (ANOVA) was performed using aluminium percentage by weight (wt%) and sizes (Ps) as the predictor variables. Results indicated different chemical formulae of the composite phases. A maximum of 124.44 % increase in flexural modulus was found at 12 wt% reinforcement addition. Probability value, 0.000 for each of wt% and Ps affirm evenly significant influence of both variables on flexural modulus of the composites. Hence, the developed multiple regression model can be used for predicting the flexural modulus of epoxy particulate composites within and outside the scope of experiment.

“…Besides, the use of waste products and waste materials as polymer raw materials will contribute to even greater cost reduction, and most importantly, a solution to the number of acute environmental and socio-economic problems. This will also expand their possible recycling and reuse in the form of high-tech metal-filled polymer composites [21][22][23].…”

Utilization of Polypropylene in the Production of Metal-Filled Polymer Composites: Development and Characteristics

et al. 2020

Metal-filled composites based on polypropylene waste have been successfully obtained with an injection molding method of metalized polymer raw materials. Using the model polymer, the peculiarities of the formation of the copper layer in solutions of chemical metallization on the polypropylene surface were investigated and the main factors influencing this process were established. The main influence on the rate of reduction of copper in solutions of chemical metallization has the concentration of copper sulfate, sodium hydroxide, and EDTA-Na2. It was shown that the efficiency of the copper plating process also strongly depends on polymer processing, which follows the activation. In case of the use of simple activation, it is not possible to obtain metalized raw materials with high efficiency. Additional processing of activated polymer raw materials is required to carry out the process with high efficiency. The amount of reduced copper on the polymer surface can be adjusted by changing the concentration of the components of the chemical metallization solution, as well as the degree of loading of the polymer raw material. Examination by electron scanning microscopy of the obtained metalized polypropylene showed that the copper coating on the polymer particles is formed with a high degree of surface coverage. The formed copper coating is free of copper oxides, which is confirmed by X-ray diffraction studies and analysis of the spectrum of characteristic X-rays. Metal-filled composites have been characterized by the effect of copper on mechanical and rheological (MFR) properties. The Differential Scanning Calorimetry (DSC) and Thermogravimetric (TG) methods show a certain effect of metal on the magnitude of thermal effects and the rate of weight loss.

“…The result showed that the electrical and thermal characteristics enhanced with adding copper powder while, the mechanical properties decreased compared with pure polyethylene matrix. Pargi et al [15] investigated the influence of mixed copper particle size filled epoxy composites on the thermal, electrical, and mechanical characteristics. The result showed enhancement in overall characteristics of epoxy composites filled with copper particles.…”

In the present investigation, the fatigue life detection of composite material by adding copper particle of about than 25 μm diameter with 5, 10, 15 % volume fraction, as a reinforcements into the unsaturated polyester polymer composite material on fatigue life detection of composite material were studied experimentally and numerically. Composites were made using hand lay-up technique and evaluated for mechanical and fatigue properties in accordance with ASTM standards. The experimental results of the tensile test showed that adding 15% of copper particle in unsaturated polyester gives maximum ultimate tensile stress. Fatigue tests including test rod specimens made of composite materials under completely reversed cyclic loading in a rotating cantilever reversed bending machine. It is found that, the fatigue life and fatigue strength increase with increasing in the copper percentage volume fraction in unsaturated polyester resin compared with pure polyester composites. The experimental work was compared with numerical work, which was done by using ANSYS/19 and good agreement has been found. The maximum overall difference between the experimental and numerical work was around 9 %.
