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:

Staphylococcus aureus is a feared pathogen (MRSA, multi-resistant S. aureus) due to frequent resistances against many antibiotics, especially in hospital infections. Researchers at the Paul-Ehrlich-Institut have identified immunological processes that prevent a successful immune response directed against the pathogenic agent. The delivery of bacterial proteins with RNA adjuvant or messenger RNA (mRNA) into immune cells allows the re-direction of the immune response towards an active defense against S. aureus. This could be of significant importance for the development of an effective vaccine. PLOS Pathogens has published these research results online on 25 May 2017.
Staphylococcus aureus (S. aureus) is a bacterium that colonizes by far more than half of the skin and the mucosa of adults, usually without causing infections....
Physicists from the University of Würzburg are capable of generating identical looking single light particles at the push of a button. Two new studies now demonstrate the potential this method holds.

An international team of physicists has monitored the scattering behaviour of electrons in a non-conducting material in real-time. Their insights could be beneficial for radiotherapy.
We can refer to electrons in non-conducting materials as ‘sluggish’. Typically, they remain fixed in a location, deep inside an atomic composite. It is hence...
Two-dimensional magnetic structures are regarded as a promising material for new types of data storage, since the magnetic properties of individual molecular building blocks can be investigated and modified. For the first time, researchers have now produced a wafer-thin ferrimagnet, in which molecules with different magnetic centers arrange themselves on a gold surface to form a checkerboard pattern. Scientists at the Swiss Nanoscience Institute at the University of Basel and the Paul Scherrer Institute published their findings in the journal Nature Communications.
Ferrimagnets are composed of two centers which are magnetized at different strengths and point in opposing directions. Two-dimensional, quasi-flat ferrimagnets...
