Glass fiber reinforced polymer (GFRP) composite pipes are mostly used in transmission lines of submarine oil, natural gas, and chemical fluids. The alterations mechanical characteristics applications great importance to the lifespan material. Some important properties materials density hardness value. In this study, changes values GFRP which were unexposed seawater exposed for 1, 2 3 months inv...

This paper deals with 21 species of Hishimonus Ishihara and two species of Litura Knight from the Indian subcontinent. The following new species are described: Hishimonus acuminatus sp. nov. (India: Mizoram), H. distinctus sp. nov. (India: Karnataka, Kerala, Tamil Nadu. Sri Lanka), H. dwipae sp. nov. (Sri Lanka), H. longisetosus sp. nov. (India: Karnataka), H. spicans sp. nov. (India: Karnataka...

Seven species of Hishimonus Ishihara are recorded in Thailand, four of which were previously recorded from neighbouring countries and three new species described herein: Hishimonus pallidus sp. nov., H. diffractus sp. nov. and H. gillespiei sp. nov. The other four species are H. concavus Knight, previously known from the Philippines, H. subtilis Knight recorded from Singapore, H. aberrans Knigh...

Glass Fiber Reinforced Polymeric (GFRP) Composites are most commonly used as bumpers for vehicles, electrical equipment panels, and medical devices enclosures. These materials also widely structural applications in aerospace, automotive, providing alternatives to traditional metallic materials. The paper fabricated epoxy polyester resin composites by using silicon carbide various proportions al...

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. ...

Glass/carbon fiber reinforced plastic (GFRP/CFRP) and hybrid components have attracted increasing attention in lightweight applications. However, residual stresses induced the manufacturing process of these can result warpage and, eventually, negatively affect mechanical performance composite structures. In present work, GFRP, CFRP, GFRP/steel CFRP/steel were manufactured through prepreg-press-...

This study discusses the behavior of ambient-cured circular geopolymer concrete specimens tested under different loading conditions. Twelve were cast and to investigate influence type reinforcement, that is, steel glass fiber-reinforced polymer (GFRP), pitch transverse conditions (concentric axial load, 15 35 mm eccentric four-point bending). The load carrying capacity, confinement efficiency, ...

Characterisation of materials subject to high velocity deformation is necessary as many materials behave differently under such conditions. It is particularly important for accurate numerical simulation of high strain rate events. High velocity servo-hydraulic test machines have enabled material testing in the strain rate regime from 1 – 500 ε/s. The range is much lower than that experienced un...

Fibre composites are being used in various applications from aerospace, military, marine boats and submarine to renewable energy generation. Higher energy demands across the developed and growing world for the usage and replacement of conventional materials with polymer composite materials for engineering applications which is always questioned by the end user, unless the research oriented reli...
