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. ...

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)...

This paper is focused on using foam concrete as structural element in polymer-concrete composite plate girders. Trial mixes of foam concrete and different proportions of foam agent were considered to obtain the suitable mix that can be used as structural element in composite girders system. Details of the experimental investigations on foam concrete precast slabs and polymer-concrete composite ...

A fiber Bragg grating (FBG) strain patch specially adapted for long-term and high-strain applications has been developed and characterized. The design concept for the patch is based on a glass-fiber reinforced plastic (gfrp) carrier material. The developed concept for the FBG integration into the carrier material was derived from reliable integration procedure of FBG sensors into composite stru...

Shape, thickness and stacking sequence optimisation of a damage tolerant hybrid (GFRP-CFRP) composite laminate is performed using the commercial Optistruct solver. The results study are compared to both benchmark non-damage CFRP (without protective surface GFRP plies known as type 1 laminate) traditionally optimised CFRP-GFRP (having X shape 2 laminate), designed tested in previous study. manuf...

Reinforced concrete structures consists of two main components and the behavior of these structures influenced by gender and material properties, in order to investigate the behavior of concrete reinforced beam that most important flexural element in reinforced concrete structures, we chosen High Strength Concrete (HSC) for concrete and GFRP and steel bars for reinforcement. For compare the new...
