Interlaminar shear strength (ILSS) of fiber reinforced polymer composite is an important property for most of the structural applications. Matrix modification is an effective method used to improve the interlaminar shear strength of composite. In this paper, EPON 862/w epoxy system was modified using Tetraethyl orthosilicate (TEOS) electrospun nanofibers (ENFs) which were produced using electro...

The main purpose of this study is an experimental investigation and comparison the mechanical properties pultruded glass fibre reinforced polymer composite based on polyester vinylester resin. For purpose, specimens were cut from walls square tube profile along to fibres direction. such as ultimate tensile strength bending strength, modulus flexural obtained. It was observed that using vinyl es...

We present THz time-domain spectroscopy measurements on glass-fibre reinforced polymers. The experimental set-up consists of a standard free-space THz spectrometer with photoconductive emitter and detector antennas driven by a femtosecond laser source. Single-point measurements to precisely obtain the THz properties of the sample are performed as well as two-dimensional images by scanning the s...

Polyacrylonitrile (PAN)and pitch-based carbon fibres are widely used as a reinforcement in composite materials such as carbon fibre reinforced plastics, carbon fibre reinforced ceramics, carbon-carbon composites and carbon fibre reinforced metals, because of their high specific strength and modulus. Such composites have become a dominant material in the aerospace, automotive and sporting goods ...

STATEMENT OF PROBLEM Techniques and recommendations for the restoration of endodontically treated teeth have changed from the use of custom cast metal post and core system to glass fiber-reinforced (GFRC) post and composite core system. Has this latest prefabricated glass fiber reinforced post and composite core system increased the fracture resistance of teeth and reduced the incidence of unre...

PURPOSE The aim of this study was to compare the flexural strength of polymethyl methacrylate (PMMA) and bis-acryl composite resin reinforced with polyethylene and glass fibers. MATERIALS AND METHODS Three groups of rectangular test specimens (n = 15) of each of the two resin/fiber reinforcement were prepared for flexural strength test and unreinforced group served as the control. Specimens w...

This work investigates the tensile testing of glass fibre-reinforced polymer (GFRP) composite material and its most influencing parameter. The GFRP constitutes bi-axial glass-fibre epoxy-matrix. three parameters considered for test are load, elongation, thickness, experiment's factorial design is L9 orthogonal array. percentage contribution extension, thickness stress strain calculated using va...

With advances in material science and technology multitude of treatment options are available for traumatically missing anterior tooth. It can be implants, porcelain to metal bridges, Maryland bridges or orthodontic treatment. Development of fibre-reinforced composites (FRCs) has opened a new perspective in such cases. The fibre-reinforced composites have better flexural strength and fracture r...

the objective of this experimental work was to assess the drop impact damage onwoven glass fibre reinforced polymer composite laminate through online method and offlinemethod. online monitoring of drop impact damage was carried out by acoustic emission (ae)technique and ae signals during the drop impact test were captured. from the analysis of aesignals, it was observed that as the impact energ...

Poly(glycerol sebacate) (PGS) is an elastomeric polymer which is attracting increasing interest for biomedical applications, including cartilage regeneration. However, its limited mechanical properties and possible negative effects of its degradation byproducts restrict PGS for in vivo application. In this study, a novel PGS-bioactive glass fiber (F18)-reinforced composite was developed and cha...
