“…To find a suitable mass scaling factor, different mass scale factors are tested for otherwise constant simulation parameters. For this, mass scaling factors are chosen in the following set [1,4,16,64,256], where a mass scaling factor of 1 implies no mass scaling after all. The resulting energies and run times are compared.…”

“…These composites offer enhanced density specific strength, stiffness, and impact resistance, rendering them highly desirable for applications across various industries such as automotive, aerospace, and sporting goods [2]. In light of global challenges regarding overall resource consumption [3] the inherent recyclability of thermoplastic polymers represents a decisive advantage over thermoset polymers [4]. Performance of FRTPs hinges on interface quality and integrity between reinforcing fiber and matrix [5,6].…”

The objective of this paper is to investigate the debonding behavior of the interface between continuously and discontinuously fiber reinforced thermoplastics using the climbing drum peel test. The study emphasizes the importance of considering different climatic boundary conditions due to the properties of thermoplastics. Specimens with varying moisture contents are prepared and tested. It is observed that an increase in moisture content initially results in a higher fracture surface energy being required to separate the two materials, but a further increase results in a decrease of the required energy. The study presents an explanatory model of increasing plasticization of the polymer due to increased polymer chain mobility, which results in more deformation energy being required to propagate the crack. The experiment is also modeled numerically for the first time with cohesive surfaces, which successfully reproduces the force-displacement curve in the experiment.

Small format plastics are defined as being less than 2 in. long in two or more dimensions and include items such as loose bottle caps, small cosmetic packaging, and toothbrushes. Current material recovery facility (MRF) infrastructure is usually not designed to recover these smaller objects which typically fall through screens in the glass separation unit operation. A cyclone separation process has been developed to separate the small-format plastics from the glass, improving the purity of the glass stream and allowing the smaller plastics to be returned to the plastic sorting stream. Utilizing density, the cyclone sends the lighter materials through a side outlet (plastics) and collects the heavier materials (glass) through the bottom, resulting in two purified outlet streams. With the current small-scale prototype, plastic separation efficiencies greater than 94% have been observed. The life-cycle assessment and technoeconomic analysis indicate that this new separation step would increase the global warming potential savings and improve the profitability of MRFs.
