Natural fibres are possible substitutes for glass fibre in composite production because of their light weight, ease and biodegradability. The present study involves the use Taguchi grey relational analysis to optimize process parameters an epoxy based reinforced with sisal fibre. optimized Percentage by weight reinforcement, curing temperature, post time compounding pressure. A L16 orthogonal a...

Introduction : Polyetheretherketone (PEEK) is an aromatic, rigid semi-crystalline thermoplastic with excellent mechanical properties and bone-like stiffness, and good biocompatibility [1-2]. Moreover for biomedical applications, particularly in the area of load-bearing orthopaedic applications [3] PEEK is able to be repeatedly sterilized, and shaped by machining or injection moulding. Devices u...

In the present study, the mechanical properties of self-compacting concrete were investigated after the addition of different amounts of ZnO nanoparticles. The zinc oxide nanoparticles, with an average particle size of about 30 nm, were synthesized and their properties studied with the help of a scanning electron microscope (SEM) and X-ray diffraction. The prepared nanoparticles were partially ...

This paper presents a three-dimensional nonlinear degrading stiffness model capable of capturing stiffness degradation in bilateral directions for earthquake response analyses of reinforced concrete bridges. Stiffness degradations due to flexural and shear damage are considered. The model can trace the progress of damage from initial failure through gradual degradation of the member stiffness d...

This work describes the study to investigate and compare the mechanical and thermal properties of raw jute and glass fiber reinforced polyester hybrid composites. To improve the mechanical properties, jute fiber was hybridized with glass fiber. Polyester resin, jute and glass fibers were laminated in three weight ratios(77/23/0, 68/25/7 and 56/21/23) respectively to form composites. The tensile...

Recent past decades have witnessed remarkable advances in composites with potential applications in biomedical devices, aerospace, textiles, civil engineering, energy, electronic engineering, and household products. Thermoset polymer composites have further enhanced and broadened the area of applications of composites. In the present work epoxy-BMI toughened-silica hybrid (RHA/DGEBA-BMI) was pr...

This paper reports the strength behaviour of concrete containing three types of recycled polyethylene terephthalate (PET) aggregate. Results are also analysed to determine the PET-aggregate’s effect on the relationship between the flexural and splitting tensile strengths and compressive strength and to know whether the relationships between compressive strength and other strength characteristic...

The effects of surface treatment of flax fibers featuring vinyltrimethoxy silane (VTMO) and maleic anhydride-polypropylene (MAPP) on the mechanical properties of flax/PP composites were investigated. α-polypropylene (α-PP) and β-polypropylene (β-PP) were used as matrices for measuring the mechanical properties of the flax fiber/polypropylene (flax/PP) composites. Flax/PP composites composed of ...

Research on wood-flour-filled polypropylene has primarily focused on one species of wood flour and one or two broad particle-size distributions. To fully exploit the use of wood flour as a filler, the effects of species and particle size need to be examined. This study focused on the effects of both of these variables on the properties of polypropylene filled with wood flour. To examine the eff...
