The comfortable and successful socket represents the core purpose of the current work for the lower limb prosthetic, which must be satisfied two items, stiffness and elasticity for duration and damping purposes, respectively. In the present work, demonstrated a novel composite material made mainly from silicon and epoxy, where is the silicon material for damping and epoxy for rigidity. Eight models for a different component of two materials under study are performed. Model 4 of 15% silicon and 85% epoxy is fulfillment the optimum strength and elasticity needed for a succeeding socket. The methodology of the present work is divided into two parts experimental and numerical results. The experimental results, including manufacturing the composite models and the compression test, are done for all models. The numerical results are determined by a virtual simulation of the socket using the AUTODESK INVENTOR PROGRAM. The numerical results proved that model 4 satisfied all requirements from stresses, deformations, strain, and factors of safety which are obtained for the present material and selected traditional materials that were used as socket material in past research. Model 4 provides a superior stiffness in comparison with polypropylene and high-density polyethylene reaching 456 % and 21.8 %, while the softening of the new composite material for the socket is approximately similar to the polypropylene but larger than stiff glass fiber reinforced plastic reached to 317 %. Finally, the major observations that can be demonstrated from the current work are proposing a lighter, stronger, more elastic, and safer socket. [ABSTRACT FROM AUTHOR]

This research aims to examine the mechanical properties of hybrid nanocomposites manufactured through a hand layup process using natural fibers such as hemp and pineapple, synthetic fiber such as glass fiber as reinforcement, and LY556 epoxy with aluminum oxide as a nanofiller. The mechanical characteristics of composites are tested as per the ASTM. The study demonstrated that the mechanical properties of the composites were greatly enhanced by the inclusion of nanofillers. The Tensile, Flexural, and Impact strength were increased respectively, compared to the composites without nanofillers. Moreover, the composites exhibited a good balance of properties, including stiffness, strength, and toughness. According to the experimental study, it was suggested that the developed hybrid nanocomposites have great potential for various structural applications for automotive sector. [ABSTRACT FROM AUTHOR]

In the medical sector, the development of an implantable device with sensing and transmitting capabilities like pressure and temperature has become increasingly crucial. The external receiver of the system can be placed close to and it should be far away from the patient. Implantable device technology is beneficial for the patients in diagnosing serious ailments such as a stroke or cardiac arrest. This research work aims to use a Composite Ground Structure (DGS) for a patch antenna used in biomedical settings. This antenna is fabricated with fibre glass cloth and epoxy resin, and it is ideal for 2.9GHz frequency which lies in the unlicensed band. Furthermore, its design complies with the FCC regulations for this frequency range. [ABSTRACT FROM AUTHOR]

This research deals with the comparison of impact strength of novel hybrid synthetic fibre aluminium mesh reinforced epoxy composite with aluminium mesh epoxy composite without any fibre. Materials and Methods: In this research, synthetic fibre aluminium mesh epoxy composites are fabricated by varying fibres such as carbon, kevlar, glass fibre and no fibre are designated as (CFAML), (KFAML), (GFAML), (AML). The experimental group consists of CFAML, KFAML, GFAML and the control group is AML. The samples per group were 20 and the total number of groups were 4. The Charpy impact method was used to evaluate the impact strength. Result: The mean impact strength for CFAML, KFAML and GFAML composites are 274.95 kJ/m², 248.07 kJ/m² and 133.31 kJ/m² respectively, but for the control group AML the impact strength value is 107.94 kJ/m². The values of impact strength from the ANOVA analysis are significant (P<0.05). Conclusion: Within the limits of the study, it is observed that the addition of different fibre types plays an important role in enhancing the composite's impact strength. The carbon fibre reinforced aluminium mesh epoxy composite has higher impact strength than kevlar and glass fibre composites. [ABSTRACT FROM AUTHOR]

This research is based upon analyzing and comparing impact strength of hybrid composites reinforced with chromium alloy which is compared with Epoxy resin-chromium alloy laminate.material which was investigated in this particular research was three groups of hybrid composites namely, carbon fibre reinforced chromium alloy composite which is denoted as CfCr, kevlar fibre reinforced chromium alloy composite which is denoted as KfCr, glass fibre reinforced chromium alloy composite which is denoted as GfCr. control group composite is an epoxy polymer reinforced chromium alloy which is denoted as EpCr. The metal used here is chromium alloy metal of grade CrNi60Wti. Totally 20 samples were machined and tested for impact strength under selected parameters. The mean impact strength of the CfCr was found to be 13.200 J, the mean impact strength of KfCr was found to be 10.9450 J, the mean impact strength of Gfcr was found to be 7.9150 J and the mean impact strength of the comparative group EpCr was found to be 7.1800 J. The significance value among the four composites was found to be 0.002 (P<0.05). Within scope of this study, it is derived that overall impact strength and absorption energy of hybrid composite is fairly greater than that of conventional epoxy resin-chromium alloy laminate.

Composite materials play important role in many industrial applications. Researchers are working on fabrication of new composite materials to enhance the applicability of these materials. Chopped strand mat glass fibre reinforced polymer composites is widely used in many industrial applications particularly in the automotive industry due to advantages such as low weight, ease of processing, price and noise suppression., The objective of the present work is to analyse mechanical and wear behaviour of chopped strand mat E-glass fiber, reinforced in epoxy matrix with carbon powder as filler. Three different types of composites are fabricated using 10% carbon, 20%carbon and 30% carbon with epoxy resin and hardener. The epoxy resin and hardener are mixed in 10:1 weight ratio. The present work shows that incorporation of carbon filler into E-glass fiber epoxy reinforced composites modifies the hardness compressive and wear properties of the composites when compared with unfilled E-glass epoxy composite.
