There has been an enormous increase in using of carbon fiber reinforced thermoplastic (CFRTP) especially reinforce polyetherketoneketone (CF/PEKK) automotive and aeronautical industries. However, fundamental material removal mechanism such never elucidated the literature. In this work, finite-element (FE) method is deployed microscale numerical model considering fiber, matrix interface establis...

To simulate the forming process of a unidirectional (UD) glass fiber non-crimp fabric (NCF) for wind turbine blades, material needs to be characterized. In this way, input model simulation can generated. One important deformation characterize is out-of-plane bending. A number test setups have been described in literature but it not clear which setup more appropriate UD NCF under consideration. ...

We have developed a method for the three-dimensional (3D) printing of continuous fiber-reinforced thermoplastics based on fused-deposition modeling. The technique enables direct 3D fabrication without the use of molds and may become the standard next-generation composite fabrication methodology. A thermoplastic filament and continuous fibers were separately supplied to the 3D printer and the fi...

The orientation of unidirectional carbon fibers (UDCFs) in a manufacturing process is critical to the mechanical properties fiber reinforced plastics (CFRPs). This study presents method monitor UDCFs on mold using electrical resistance during CFRP process. An equivalent model for was proposed develop an situ sensor mold. investigated terms its orthotropic properties. technique can have strong i...

Using natural hemp fibers to reinforce the tensile characteristics of polymer matrix composites is investigated in this article. The fibers were applied to the epoxy matrix in unidirectional and hybrid tissue forms. After preparation of standard tensile stress test specimens via manual layup, the standard tensile test was done.  Young’s modulus, ultimate tensile stress, and the amount of absorb...

The most common studies in the literature are those analyzing fatigue life under cyclic loading for flax fiber-reinforced composites. A novel type of staple fiber yarn made from tow with almost unidirectional orientation and a quasi-unidirectional fabric was developed composite applications. Additionally, hybrid material glass produced demonstrator component (an axle tie narrow-gauge railway). ...

background: scuba diving is one of the fastest growing sports in the world. the objective of this study was to evaluate the effect of pressure variations to which divers are exposed on the pull out strength of glass fiber post luted with different cements. materials and methods: in this in vitro study, 120 extracted, single-rooted lower premolars were endodontically treated. they were randomly ...

in this research, a braiding-pultrusion production line is developed by modifying a conventional textile maypole braiding machine and adding it to a pultrusion line for production of braid-pultruded (bp) composite rods. in order to evaluate the mechanical properties of bp rods and study the effect of some braiding parameters, they were produced with different braid roving linear densities and b...

This paper investigates the grinding performance of epoxy matrix composites reinforced by unidirectional carbon fibres, using an alumina grinding wheel. Emphasis was placed on understanding the effect of fibre orientations and grinding depths on the grinding force and surface integrity, and on understanding the grinding mechanisms, with a comparison to orthogonal cutting. It was found that grea...
