The incessant emergence of failures in mining roofs, along with escalating demands for high and sustainable roof support products such as resin anchor bolt capsules (resin), necessitates strengthening these elements. This study explores the transformative influence Titanium oxide nanoparticles (TiO2) its concentration on chemical properties, stability, thermal performance polyester (UPE) nanocomposites. investigation was carried out using Fourier-transform infrared (FTIR), Raman spectroscopy, X-ray diffraction (XRD). Rheological behavior assessed a Brookfield viscometer, while stability examined via thermogravimetric analysis (TGA, DTG, DTA). From results obtained, addition nanoparticle TiO2 yielded little significant change shift FTIR wavelength. However, substantial peak disappearance from peaks UPE neat compared to composites. is associated an increase crystallinity due content. confirms seamless presence anatase matrix. curing kinetics exhibit 50-second reduction time reach exothermic when nanomaterial content reaches 3% TiO2. An leads shorter at higher temperature, indicating improved cure rates. substantiates enhanced stabilities increasing content, affirming positive impact infusion resilience stability.

Investigation on mechanical and thermal behaviour of graphene bonded carbon/Kevlar hybrid fabric polymer composites

Journal of Engineering and Applied Science, Год журнала: 2024, Номер 71(1)

Опубликована: Май 11, 2024

Abstract The present research is aimed to understand the influence of graphene-reinforced carbon/Kevlar hybrid fabric epoxy composites. Samples HG0, HG2, HG4, and HG6 are fabricated using four layers mat with varying graphene weight percentage as 0, 2, 4, 6 wt.%, respectively. Mechanical characterizations such hardness, tensile, flexural strength were individually assessed. Thermal stability evaluated through thermos-gravimetric analysis. Composite high filler loading showed 71% 114.4% greater tensile compared unfilled HG0 specimen. Similarly, exhibited thermal stability. Inclusion particles in higher concentration improved interfacial bonding between fibre/matrix/filler system. Fracture surfaces analysed scanning electron microscopy failure mechanisms.
