In this paper, interphases in unidirectional fiber-reinforced composites under transverse loading are modeled by an advanced boundary element method based on the elasticity theory. The interphases are regarded as elastic layers between the fiber and matrix, as opposed to the spring-like models in the boundary element method literature. Both cylinder and square unit cell models of the fiber-inte...
OBJECTIVES The aim of this study was to evaluate and compare the load-bearing capacity of fractured incisal edge of maxillary permanent central incisors restored with a nanocomposite and a glass fiber-reinforced nanocomposite. MATERIALS AND METHODS Thirty-six extracted sound maxillary central incisors randomly divided in three groups were used for the present study. Group I (control) containe...
an investigation of stress-strain behavior of frp-confined concrete under cyclic compressive loading
one important application of fiber reinforced polymer (frp) is to confine concrete as frp jackets in seismic retrofit process of reinforced concrete structures. confinement can improve concrete properties such as compressive strength and ultimate axial strain. for the safe and economic design of frp jackets, the stress-strain behavior of frp-confined concrete under monotonic and cyclic compress...
For effective applicability of reinforced cork, cork composites with metal, glass fiber, and carbon fiber were developed, the effects reinforcing materials on mechanical properties investigated. The bending moduli elasticity (MOE) in 32.7–35.9 MPa range, while strength values 1.62–1.73 range. performance decreased order cork-metal > cork-carbon cork-glass fiber. MOEs improved by 29%–41% comp...
Abstract The reduction of weight elements is considered as a major objective several manufacturing companies. This will help in growing application sections the used fiber composites for important structural elements. Modern metal laminate (FML) having lightweight properties established to be instead other substances different applications including those related aerospace industrial sector. Fi...
این مطالعه روی ستونهای مستطیلی و دایره ای بتن مسلح و غیرمسلح تقویت شده با کامپوزیتهای cfrp انجام شده است. هدف از آن تعیین رفتار این ستونها تحت بار محوری خالص و بار محوری خارج از مرکز (ترکیب نیروی محوری و لنگر خمشی) با روش آزمایشگاهی و عددی می باشد. در قسمت مطالعه آزمایشگاهی، 10 عدد نمونه ستون بتن مسلح بزرگ مقیاس (مقیاس یک دوم) ساخته شده و پس از تقویت با کامپوزیتهای cfrp تحت بار محوری خارج از مر...

in the present study, modelling and vibration analysis of carbon nanotubes/ fiber/ polymer composite microplates are investigated. the governing equations of the carbon nanotubes/ fiber/ polymer composite microplates are derived based on first order shear deformation plate theory, rather than other plate theories, due to accuracy and simplicity of polynomial functions. the modified couple stres...
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...
