Each of the hybrid composite fabricated: Cotton fabric reinforced hybrid composite (CtRHC) and Polyester fabric reinforced hybrid composite (PeHC), was reinforced with two, three and four layers cotton or polyester. The control samples were the composite without any textile fabric reinforcement.
Flexural strength, impact strength, water absorption and thickness swelling tests were conducted to determine the mechanical and physical properties of the fabricated hybrid composites respectively.
It was found that the flexural strength of these fabrics reinforced hybrid composites improved as compared to the control sample, which was without textile fabric. The result of flexural modulus of the hybrid composite fabricated demonstrated similar trend with its flexural strength. The flexural modulus of the hybrid composites improved with the presence of textile fabrics. Samples reinforced with textile fabrics exhibited higher values than the control sample. The reinforcement with 4 layers of textile fabric tended to decrease the flexural modulus slightly.
The cotton fabric reinforced hybrid composite samples had better flexural but lower impact strength in comparison with the polyester reinforced hybrid composites. All newly fabricated hybrid composites also recorded to have a lower water absorption than the control sample.
The cotton hybrid showed lower water absorption than the polyester hybrid due to poor adhesion between polyester and urea formaldehyde. Both types of hybrid composite showed higher values than the control in thickness swelling.
In short, polyester strengthened with particles of rubber wood and coconut shell is stronger than the normal ones.Information Contacts:

A new manufacturing technique uses a process similar to newspaper printing to form smoother and more flexible metals for making ultrafast electronic devices.
The low-cost process, developed by Purdue University researchers, combines tools already used in industry for manufacturing metals on a large scale, but uses...
For the first time ever, scientists have determined the cosmic origin of highest-energy neutrinos. A research group led by IceCube scientist Elisa Resconi, spokesperson of the Collaborative Research Center SFB1258 at the Technical University of Munich (TUM), provides an important piece of evidence that the particles detected by the IceCube neutrino telescope at the South Pole originate from a galaxy four billion light-years away from Earth.
To rule out other origins with certainty, the team led by neutrino physicist Elisa Resconi from the Technical University of Munich and multi-wavelength...
For the first time a team of researchers have discovered two different phases of magnetic skyrmions in a single material. Physicists of the Technical Universities of Munich and Dresden and the University of Cologne can now better study and understand the properties of these magnetic structures, which are important for both basic research and applications.
Whirlpools are an everyday experience in a bath tub: When the water is drained a circular vortex is formed. Typically, such whirls are rather stable. Similar...
Physicists working with Roland Wester at the University of Innsbruck have investigated if and how chemical reactions can be influenced by targeted vibrational excitation of the reactants. They were able to demonstrate that excitation with a laser beam does not affect the efficiency of a chemical exchange reaction and that the excited molecular group acts only as a spectator in the reaction.
A frequently used reaction in organic chemistry is nucleophilic substitution. It plays, for example, an important role in in the synthesis of new chemical...
Optical spectroscopy allows investigating the energy structure and dynamic properties of complex quantum systems. Researchers from the University of Würzburg present two new approaches of coherent two-dimensional spectroscopy.
"Put an excitation into the system and observe how it evolves." According to physicist Professor Tobias Brixner, this is the credo of optical spectroscopy....
