Ho Chi Minh City, February, 2023 REVIEWER (Sign with full name) ACKNOWLEDGEMENTS As the name suggests, a CAPSTONE PROJECT is a subject that synthesizes all knowledge and is the final requirement to complete a university education program, and this is also a time to look back on the road that I have experienced. We are the lucky ones to have the opportunity to study at the University of Technology and Education of Ho Chi Minh City, receive helpful knowledge from the excellent lecturers here, and have the opportunity to meet friends, and the seniors are willing to share their experiences with the juniors.
Along with that, the school always creates opportunities for students to meet, exchange ideas, and learn through organizing business trips and seminars. And especially the school also favors students by annually organizing "Job Day". Thanks to these events, many students can do internships and jobs with businesses and companies that match their requirements. We would also like to thank our parents and relatives sincerely.
Those who contributed to our upbringing have created conditions that have allowed us to progress to where we are today. To complete this capstone project, our team did not forget to express our deep respect and gratitude to the following: Ph. Nguyen Nhut Phi Long, Ho Chi Minh City University of Technology and Education, spent his precious time helping and creating the best conditions for the team to complete the project successfully. Teammates DT52 and Ph.
Tran Van Tron helped us during the mold design and fabrication process to complete the specimen pouring experiment. Once again, we also do not forget to thank the teachers at Ho Chi Minh City University of Technology and Education for their dedication to teaching and imparting the knowledge and foundation for us to complete the assigned project successfully. We sincerely thank you! Students Truong An Ha Nhat Truong ABSTRACTS Project name STUDY ON THE EFFECT OF COMPONENT CONTENT ON MECHANICAL PROPERTIES OF COCONUT COIR FIBER POWDER- PLASTIC COMPOSITE MATERIAL In today's world, with the continuous development and innovation of materials in general, and composite materials in particular, the requirements and requirements for mechanical properties are becoming increasingly concerned and enhanced and must be taken into account more optimization. After studying the problem through articles and documents, we found that the mechanical properties of composite materials depend not only on the materials they are made of but also on the content of each component that makes them up.
as hardeners and fillers. Because we want to learn more and find out the ratio of components to create the optimal mechanical properties of composite materials, today we would like to do the topic "Study on the effect of component content on mechanical properties of coconut coir fiber powder-plastic composite material". In this topic, we have studied the mechanical properties of composite materials with the combination of epoxy, hardener, and coir powder, with coir powder content of 6%, 8%, and 10%, while the ratio of epoxy and hardener is 3:1, 3:1. Because of the time-limited and lack of knowledge in many aspects, the team's product has mechanical properties that are not as perfect as expected.
Therefore, these initial obstacles are a premise for us to understand better the material's properties and components and a stepping stone for the team to improve the mechanical properties even further.
