“…Since the low density of syntactic foams is the most promising feature that enables their applications, the trends in mechanical properties are analyzed with respect to density of HDPE matrix with different fillers and are presented in Figure 11 [31][32][33][34][35][36][37][38][39]. The data are extracted from published literature and are plotted with respect to density.…”

Rapid production of high quality components is the key to cost reduction industrial applications.The present work is the first attempt of manufacturing syntactic foams, hollow particle filled lightweight composites, using an industrial scale injection molding machine. High density polyethylene (HDPE) is used as the matrix material and fly ash cenospheres are used as the filler. Development of syntactic foams with cenospheres serves dual purpose of beneficial utilization of industrial waste fly ash and reduction in the cost of the component. The pressure and temperature used in injection molding process are optimized to minimize fracture of cenospheres and obtain complete mixing of cenospheres with HDPE. The optimized parameters are used for manufacturing syntactic foams with 20, 40 and 60 wt.% cenospheres. With increasing cenosphere content, density and strength reduce and modulus increases. Surface modification of constituents results in rise in strength with increasing filler content. A theoretical model based on a differential scheme is used to estimate the properties of cenospheres by conducting parametric studies because of inherent difficulties in direct measurement of cenosphere properties. The potential for using the optimized injection molding process is demonstrated by casting several industrial components.

“…Epoxy is the most popular thermoset polymer used in structural applications such as aircraft wings, helicopter rotors, and wind turbine blades [10]. Thermoplastic HDPE is another such polymer due to its recyclability, moldability, low cost, low density, and low friction properties [11][12][13]. To name few, HDPE is used in boats, ballistic plates, and piping for fluid transfer [14].…”

Strategies are suggested for the waste utilization of industrial leather by preparing composites with epoxy and high-density polyethylene (HDPE). The addition of leather improves the average specific compression toughness of epoxy by 29%. The fracture surface analysis suggests the incorporation of leather microparticles leads to a transition of failure mode of epoxy from brittle to ductile. In addition, the dynamic strength of the leather/epoxy composite is found to be 69% higher than that of neat epoxy. However, no significant changes are observed when HDPE is infiltrated with leather. Apart from dispersing the leather particles directly in polymer, a novel strategy is presented here in which leather/HDPE microfibers are prepared and then used to reinforce the epoxy matrix. The specific compression modulus of this composite blend is 8% and 65% higher than epoxy and HDPE, respectively. Fractography is further carried out on the failed specimens to understand the failure mechanism in each composite. A change in the failure mode is observed when epoxy is reinforced either with leather particles or the microfiber. While the failure strength of the microfiber is found to be higher than epoxy, the strength of microfiber/epoxy interface is lower than that of epoxy.

“…Among them, CaCO 3 has been one of the most commonly used inorganic fillers for thermoplastics such as PVC, PP and PE because of its low cost and abundance [3,8]. In the recent years intensive research efforts have been devoted to the development of polymer properties with CaCO 3 incorporation [6,[9][10][11][12][13].…”

Comparative study of volcanic particle and calcium carbonate filler materials in HDPE for thermal and mechanical properties

2018

Usage potential of volcanic particles (VPs) in high‐density polyethylene (HDPE) composites against traditional calcium carbonate (CaCO3) was investigated for thermal and mechanical properties. HDPE composites were prepared by melt compounding and injection molding processes with various filler contents such as 6, 12, 18, and 24 wt%. Thermal properties such as melting behavior and thermal expansion behavior were analyzed by differential scanning calorimeter and dilatometry machine; respectively. In addition, mechanical properties such as tensile modulus, tensile strength and elongation at break parameters were investigated with tensile tests. After the experimental results it was shown that the use of VPs had a much larger effect in improving mechanical properties and in reducing coefficient of thermal expansion values of HDPE composites, compared with the use of CaCO3 particles. It was determined that maximum levels of thermal properties which were obtained with higher contents of CaCO3 were sufficiently achieved with lower contents of VPs such as 6 wt%. POLYM.
