The main purpose of this study is an experimental investigation and comparison the mechanical properties pultruded glass fibre reinforced polymer composite based on polyester vinylester resin. For purpose, specimens were cut from walls square tube profile along to fibres direction. such as ultimate tensile strength bending strength, modulus flexural obtained. It was observed that using vinyl es...

We report the fabrication of a coaxial electrospun scaffold with bioactive molecule in core and protein conjugated at surface. To construct scaffold, we chose polyethylene oxide for material polycaprolactone/Jeffamine blend shell.

Interest in natural fiber polymer composite has increased worldwide due to their low cost, low density and good thermal resistivity. Sisal fiber is used as reinforced in mat form and epoxy as matrix in this composite. In present work, thermogravimetric analysis and fracture behavior of composites were studied. The percentage mass loss and physical changes of composite was observed through furna...

Reinforced polymer composites have played an ascendant role in a variety of applications for their high meticulous strength and modulus the fiber may be synthetic or natural used to serves as reinforcement in reinforced composites. Glass and other synthetic fiber reinforced composites consists high meticulous strength but their fields of applications are restrained because of their high cost of...

We present terahertz transmission time-domain spectroscopy measurements on a variety of additive-polymer combinations with differing additive contents. At lower terahertz frequencies, standard polymers are transparent. When processed into compounds, their terahertz properties are distinctively affected by additives in most cases. The materials under investigation are magnesium hydroxide in line...

Facemasks have been a critical line of defense in the Covid-19 pandemic and used for decades to reduce inhalation sub-micron aerosols, including bacteria, viruses nano-materials. These facemasks leverage electrostatic charge properties non-woven electret fibre mats remove aerosols. However, topographical these not well characterized at nano-scale. In this study, we use atomic force microscopy (...

The market for composites is developing rapidly due to the widespread general requirement lightweight design in various industries. However, proliferation of fibre-reinforced limited partly lack ductility associated with these materials. Hybridisation fibres has emerged as an important strategy increase polymer composite In present work, water based dispersion was used develop a dry fibre carbo...
