Study of mechanical and morphological properties of glass fiber reinforced mo...eSAT Journals
Abstract Polymethylmethacrylate and Poly (acrylonitrile-co-butadiene) rubber were used to modify Diglycidyl ether of bisphenol A (DGEBA) type epoxy resin and cured with stoichiometric quantities of the hardener 4,4’ diamino dipheny methane. This modified epoxy resin was used as the matrix for the preparation of glass fiber reinforced composites. E- Glass fiber was used as fiber reinforcement. The morphology and mechanical properties of the composite analysed. Morphological analysis of the fractured surface of the composites indicated good adhesion between the matrix polymer and the glass fibers. Hence an enhancement in mechanical properties of the composite such as tensile, flexural, impact and fracture toughness has been observed as there has been an effective transfer of the load from the matrix to the fiber. Hence these composites which exhibit high toughness, strength and dimensional stability can be envisaged to provide valuable contribution to high performance structural applications. Keywords: Glass composites, mechanical properties, modified epoxy matrix, morphology and ternary blend

This study experimentally tested the flexural strength of concrete beams reinforced with fiber reinforced polymer (FRP) grids. Beams of four concrete grades (M35, M30, M25, M20) with dimensions of 150mmx150mmx700mm were cast and tested under two-point bending. FRP grids of two lengths (500mm and 600mm) and 2.5cm thickness were placed in the tensile zone of the beams as reinforcement. Testing found that beams with FRP grids had significantly higher flexural strength compared to plain concrete beams, with an increase of 426% for M35 grade concrete. The results indicate that FRP grids can effectively enhance the flexural strength of reinforced concrete beams.

A comparison between TiO2 nanofibers and carbon nanofibers as fibers reinforced metal matrix composites with respect to mechanical properties improvements have been made in this paper. Al and Mg have been chosen as metal matrices. The used carbon and ceramic nanofibers (Titanium Oxide) were successfully synthesized using electrospinning technique. Various weight percentage of calcined
electrospun TiO2 and carbon nanofibers (1, 3, 5 and 10%) were mixed with metal matrix and fabricated by route of powder metallurgy using High Frequency Induction heat Sintering (HFIHS). Mechanical properties of the sintered composites have been investigated. The manufactured pellets were tested for compression test, hardness and microstructures by the field emission scanning electron microscopes (FESEM), which reveals the homogeneous distribution of nanofibers in the Al/Mg matrices. In addition,
energy-dispersive X-ray spectroscopy (EDS) was employed to obtain the chemical analysis of each composite. The result shows that, the ultimate compressive strength increased to 415 MPa at 5% TiO2, which is 13.5% more than the pure Al. The hardness increased up to 64% in case of using the ceramic nanofibers as reinforcement. While using CNFs as reinforcement to the Al matrix deteriorates the
mechanical properties.

Developments of nano clay particle reinforced plastics are of growing interest towards the
emergence of new materials which enhance optimal utilization of natural resources and particularly of
renewable resources. The effects of nano clay as filler in Basalt–epoxy composite systems on the
tribological properties have been discussed in this article. Basalt fiber reinforced epoxy (BE) composite
finds widespread application in erosive environment due to its several advantages like high wear
resistance, high strength-to-weight ratio and low cost. Experiments were carried out to study the effects
of impingement angle, particle velocity and filler material on the solid particle erosive wear behavior of
BE composite. The erosive wear is evaluated at different impingement angles from 30° to 90° at three
different velocities of 23, 42, & 60 m/s. The erodent used is silica sand with the size range (150 – 280 µm)
of irregular shape. The result shows semi-ductile behavior with maximum erosion rate at 60°
impingement angle. It is observed that wear rate increases with increasing particle velocity and
decreases with increases of filler percentage. The morphology of the eroded surfaces was examined by
using Scanning electron microscopy (SEM).
This document summarizes research on incorporating polyamide 6 nanofibrous structures into glass fiber-reinforced epoxy composites to improve their mechanical properties. Experiments showed that the nanofibers had a catalytic effect on the curing of the epoxy resin, lowering its activation energy. Composites with nanofibers deposited on or between fiber layers showed increased stress at failure compared to a control without nanofibers. The deposited nanofibers in particular improved load transfer to the glass fibers. While nanofibers did not significantly increase modulus, their inclusion helped prevent delamination cracks in the composites. The research demonstrates that nanofibers can enhance some mechanical properties of glass fiber-ep

Tech transfer making it as a risk free approach in pharmaceutical and biotech iniaemedu
Tech transfer is a common methodology for transferring new products or an existing
commercial product to R&D or to another manufacturing site. Transferring product knowledge to the
manufacturing floor is crucial and it is an ongoing approach in the pharmaceutical and biotech
industry. Without adopting this process, no company can manufacture its niche products, let alone
market them. Technology transfer is a complicated, process because it is highly cross functional. Due
to its cross functional dependence, these projects face numerous risks and failure. If anidea cannot be
successfully brought out in the form of a product, there is no customer benefit, or satisfaction.
Moreover, high emphasis is in sustaining manufacturing with highest quality each and every time. It
is vital that tech transfer projects need to be executed flawlessly. To accomplish this goal, risk
management is crucial and project team needs to use the risk management approach seamlessly.

Effective broadcasting in mobile ad hoc networks using gridiaemedu
This document summarizes a research paper that proposes a new grid-based broadcasting mechanism for mobile ad hoc networks. The paper argues that flooding approaches to broadcasting are inefficient and cause network congestion. The proposed approach divides the network into a hierarchical grid structure. When a node needs to broadcast a message, it sends the message to the first node in the appropriate grid, which is then responsible for updating and forwarding the message within that grid. Simulation results showed the grid-based approach outperformed other broadcasting protocols and was more reliable, efficient and scalable.
