Adhesion test results are presented as part of an initial examination of the effect of a variety of intrinsic rock properties and environment conditions that influence the adhesive bond between rock and a thin liner. The liner material used for these tests was Tekflex, provided by FosRoc. Some of the variables examined include: rock strength (tensile/compressive strength) rock mineralogy, rock surface roughness (grain size, fracture/joint roughness), surface contamination (oil or dust), and curing environment (temperature and humidity). Under optimal conditions, adhesive strengths reaching at least 4 MPa can be achieved. Where the rock surface is contaminated with dust or the rock is weak in tension, it may be difficult to reach adhesion of 1 to 1.5 MPa.

Effects of titanate coupling agents on low density polyethylene and polypropylene blends and composites
Yılmaz, Gökhun; Bayramlı, Erdal; Department of Polymer Science and Technology (2008)
The objective of this study is to investigate the effects of titanate coupling agents on low density polyethylene (LDPE) and polypropylene (PP) blends and composites in terms of their mechanical and morphological properties. PP and LDPE composites were produced separately in a Brabender internal mixer, and CaCO3 was used as inorganic filler with compositions of 20, 40 and 60 %. PP/LDPE blends were produced in a twin-screw extruder with ratios of 75/25, 50/50 and 25/75. Their composites were prepared with ad...
Influence of zinc borate on flame retardant and thermal properties of polyurethane elastomer composites containing huntite-hydromagnesite mineral
Dike, Ali Sinan; Tayfun, Umit; DOĞAN, Mehmet (2017-11-01)
The effect of zinc borate (ZnB) was studied on the flame retardant and thermal properties of thermoplastic polyurethane containing huntite-hydromagnesite. The flame retardant properties of thermoplastic polyurethane-based composites were investigated using limiting oxygen index, vertical burning test (UL 94), thermogravimetric analysis, and mass loss calorimeter. No remarkable effect of ZnB was observed on the flammability properties of composites. UL 94 rating did not change regardless of the added amount ...
Effects of glass fiber content, 3D-printing and weathering on the performance of polylactide
Varsavaş, Sakine Deniz; Kaynak, Cevdet; Department of Metallurgical and Materials Engineering (2017)
The purpose of the first part of this thesis was to investigate how optimum mechanical properties (strength-modulus-toughness) of inherently very brittle polylactide (PLA) could be obtained by reinforcing with E-glass fibers (GF) and blending with thermoplastic polyurethane elastomer (TPU). Composites and blends were compounded by twin-screw extruder melt mixing, while specimens were shaped by injection molding. SEM analyses revealed that 15 wt% GF reinforcements and 10 wt% TPU domains, alone or together, c...
Effect of expandable graphite on flame retardant, thermal and mechanical properties of thermoplastic polyurethane composites filled with huntite&hydromagnesite mineral
Guler, Turkan; Tayfun, Umit; Bayramlı, Erdal; DOĞAN, Mehmet (2017-01-10)
The effect of expandable graphite (EG) was studied on the flame retardant, thermal and mechanical properties of thermoplastic polyurethane (TPU) containing huntite&hydromagnesite (HH). According to the flammability tests results, the synergistic interaction was observed between HH and EG. The maximum limiting oxygen index (LOI value was observed at a ratio of 1:1 (HH:EG) and the highest vertical burning test (UL-94) rating of V0 was observed at a ratios of 4:1, 3:2 and 1:1. The synergistic interaction betwe...
Effect of carbon nanotube surface treatment on the morphology, electrical, and mechanical properties of the microfiber-reinforced polyethylene/poly(ethylene terephthalate)/carbon nanotube composites
Yesil, Sertan; Bayram, Göknur (2013-01-15)
The aim of this study is to investigate the effects of carbon nanotube (CNT) chemical properties, CNT content, and molding temperature on the morphology, electrical, and mechanical properties of the microfiber-reinforced polymer composites. These composites were prepared by extrusion and hot stretching the poly(ethylene terephthalate) (PET)/CNT phase in high density polyethylene (HDPE) matrix. Surfaces of the CNT were modified by purification with strong acid mixture (HNO3 : H2SO4 mixture 1 : 1 by volume) f...
