This paper investigated the moisture absorption, mechanical behavior and the dielectric performance of hybrid and non-hybrid polymeric composites. Hand lay-up technique was used for processing carbon; glass reinforced polyester resin composites (non-hybrid) and carbon-glass/polyester hybrid composites with various fiber configurations. The maximum resistance of water absorption was obtained for...

Three-dimensional transient deformations of a laminate comprised of several unidirectional fiber reinforced layers perfectly bonded to each other and subjected to a blast load are analyzed by the finite element method with an in-house developed, verified and fully validated code with rate-dependent damage evolution equations for anisotropic bodies. The continuum damage mechanics approach employ...

Flax fibres are oftenly used for reinforcing thermoplastic to manufacture biocomposite materials exhibiting numerous advantages such as high mechanical properties, low density and biodegradability. The mechanical properties of a biocomposite material depends on the nature and orientation of the fibres, the nature of the matrix and mainly on the adhesion between fiber and the polymer matrix. The...

JCO/DECEMBER 2005 T lingual technique is considered to be one of the most difficult, requiring extended treatment times and often achieving less-than-satisfactory results. Firstand third-order tooth movements are complicated by the variable lingual tooth anatomy.1 Torque control is also more problematic; with the reduced interbracket distance, even small variations in bracket height can have a ...

The objective of the work was to investigate statistical analysis of fracture toughness of the glass fiber reinforced composites at different stacking sequences, strain rate and crack length. The glass reinforced vinylester composites prepared by hand layup technique with stacking sequences of 0/90, 45/-45 and chopped strand orientations. 3point bending for fracture toughness test for various n...

The preparation of fiber-reinforced phosphorus building gypsum composite materials (FRPGCs) is an important approach to enlarge the utilization phosphogypsum resources. Through reinforcing (PBG) with basalt fiber (BF), this article probes into effects length and content BF on working performance mechanical properties basalt-fiber-reinforced (BRPGCs) accesses toughness BRPGCs under bending loads...

Fiber-reinforced concretes with improved strength and deformation characteristics are widely used in construction. The research is aimed to study the stress-strain condition of lightweight fiber-reinforced concrete, plot diagrams analyze them. In total, four series prism specimens manufactured tested. first control composition concrete; second concrete a basalt fiber content 3%; third glass 3 %...

Abstract Basalt fiber (BF) is a kind of high-performance rising rapidly in recent years. BF typically used the field structure engineering because its high strength and modulus. The preparation BF-based composites first requires surface modification to improve interfacial bonding between resin matrix. With continuous deepening research on modification, researchers have found that special can ob...

An irregular lattice model is proposed for simulating quasistatic fracture in softening materials. Lattice elements are defined on the edges of a Delaunay tessellation of the medium. The dual sVoronoid tessellation is used to scale the elemental stiffness terms in a manner that renders the lattice elastically homogeneous. This property enables the accurate modeling of heterogeneity, as demonstr...
