Low Velocity Impact Analysis on Composite Gas Storage Tank Design

This dissertation by Lawson Onokpasah, submitted in partial fulfillment of a Bachelor of Engineering (Hons) in Mechanical Engineering, investigates the effects of low velocity impacts on compressed gas storage tanks. The research focuses on analyzing the burst pressure and mechanical behavior of filament wound composite pressure vessels. The study explores the use of composite materials to reduce weight and increase strength. The methodology includes a literature review, mathematical analysis, impact testing, and damage characterization, with the aim of understanding the impact resistance of the vessels. The project aims to evaluate the impact tolerance of fiber reinforced polymer matrix composites using ASTM standards, focusing on the effects of low-velocity impact and residual burst-pressure analysis of a cylindrical composite pressure vessel made of food grade high density polyethylene (HDPE) winded with a fibreglass filament.
