ment methods and two spec/imen diameters. Flexural strength and modulus of woven glass fiber-reinforced specimens werc significanLly greater than those without woven glass fiber (p<O.OD, Likewise, comprossive strength of reinforced specimens was signifieantly greater than those without woven glass fiber (p<O.Ol), except for specimens rcjnforced with woven glass fiber oriented at a tilt directio...

The aim of this investigation was to measure the flexural and compressive strengths and the corresponding moduli of cylindrical composite specimens reinforced with woven glass fiber. Test specimens were made by light-curing urethane dimethacrylate oligomer with woven glass fiber of 0.18-mm standard thickness. Tests were conducted using four reinforcement methods and two specimen diameters. Flex...

Background and objectives : The fracture of acrylic maxillary complete dentures is a commonly seen clinical problem which usually occurs due to heavy occlusal forces or accidental damage.The objectives of the study were to measure the impact strength of maxillary complete dentures fabricated with high impact acrylic resin and to evaluate the effect of woven E-glass fiber and silane treated glas...

STATEMENT OF THE PROBLEM In stress-bearing cavities, low fracture resistance adversely affects the longevity of the dental resin composite restorations. PURPOSE The aim of this in vitro study was to investigate the effect of glass fiber layering on the flexural strength of microfill and hybrid composites. MATERIALS AND METHODS Flexural test specimens (N = 75) were prepared according to Inte...

Vascularization enables multifunctional composites capable of self-healing, thermal regulation, electrical and magnetic modulation, and damage sensing. In this study, the effect of vascular channels on the in-plane tensile properties and damage progression of three-dimensional orthogonally woven textile composites is examined. Vascular channels are manufactured by Vaporization of Sacrificial Co...

Abstract: This paper presents the results of experimental determination of fiber bed permeability variation with porosity. Flow measurement experiments were designed to measure fiber mat permeability for fiber beds with various fiber volume fractions. Woven fiberglass, chopped fiberglass, and carbon fiber mats were used as reinforcements. The effects of reinforcement type and porosity on fiber ...

The use of natural fiber reinforced composites has continuously increased during recent years due to their low density, low cost and environmental friendliness. At current study, a preliminary investigation on the impact properties and morphologies of unsaturated polyester reinforced by jute woven fabric from the used coffee bags with different moisture contents were carried out. Additionally, ...

Tensile strength, Young's modulus, and toughness of electrospun nylon 6 non-woven fiber mats were improved by increasing individual nanofiber strength and fiber-fiber load sharing. Single-walled carbon nanotubes (CNTs) were used as reinforcement to increase the strength of the electrospun nylon 6 nanofibers. Young's modulus, tensile strength, and toughness of the nylon 6 non-woven fiber mats el...
