Evaluation on Properties of Industrial Workers Safety Helmet Using Natural Hybrid Composite 2018-28-0049
In this project work, composites were prepared by using matrix method in which good adhesion was generated by a combination of hand layup method. This experiment was conducted to evaluate the suitability of natural fiber composites using luffa fiber, palm fiber and bamboo fiber and to fabricate the safety helmet by combining these three fibers. Initially these fibers were treated in sodium hydroxide solution in order to improve fiber interfacial bonding. Generally, composites that contain treated fiber have a higher tensile modulus and greater flexural modulus than do untreated fiber composites. Here using 40% fibers and 60% matrix for fabricating natural composites and to investigate its tensile strength, flexural strength, impact strength and hardness strength. It was observed that the effects of reinforcing epoxy resin matrix with the fibers caused the composites to be more flexible and easily deform due to high strain values and reduction of high resonant amplitude. In the present study, an attempt has been made to reinforce, epoxy resin matrix with this proportion of these natural fibers and to characterize its mechanical performances to evaluate their suitability for helmet applications.
