Abstract The current study aims to investigate the Material Removal Rate (MRR) of a glass fibre reinforced polymer composite with and without natural fillers (novel Grass powder, Banana fibre). composites were made using hand layup method. We employed three sets nine specimens different each measure MRR in CNC drilling process. Drill diameter, feed rate, spindle speed all controlled variables. ...

An innovative actuation principle is introduced in this paper to drive a rotary motor using an anisotropic piezoelectric composite laminate. The driving element is a three layer laminated beam with piezoceramics sandwiched between two anti-symmetric composite laminae. By taking advantage of material anisotropy, torsional motion can be induced from in-plane strain actuation. With such structural...

Composite materials are increasingly being utilized in many products, such as aircrafts, wind blades, etc. Accordingly, the need for nondestructive inspection of composite is increasing and technologies that allow studied. Existing ultrasound methods limited their ability to detect defects due high attenuation materials, radiographic examination could pose a danger human health. Terahertz (THz)...

Background and Aim: Changing the color of resin luting cements could affect the aesthetic appearance of thin porcelain veneer. The aim of this in vitro study was to evaluate the effect of artificially accelerated aging on color stability of light-cured resin cement and flowable composite as a luting agent through the porcelain veneer. Materials and Methods: This experimental study was carried ...

No- or minimal-preparation veneers associated with enamel preservation offer predictable results in esthetic dentistry; indirect additive anterior composite restorations represent a quick, minimally invasive, inexpensive, and repairable option for a smile enhancement treatment plan. Current laboratory techniques associated with a strict clinical protocol satisfy patients' restorative and esthet...
