Underwater Rope Fatigue Testing Machine, Napoleon Nino, Andrew Pimentel
Underwater Rope Fatigue Testing Machine, Napoleon Nino, Andrew Pimentel
Mechanical Engineering
The design and fabrication of an underwater rope fatigue testing machine meant to simulate the effects of an oceanic environment and the effects on rope.
Machine Components Test, Brandon Younger, Lauren Romero, Carlos Padilla
Machine Components Test, Brandon Younger, Lauren Romero, Carlos Padilla
Mechanical Engineering
To enhance California Polytechnic State University’s Mechanical Engineering program, Dr. Schuster has sponsored Brandon Younger, Lauren Romero, and Carlos Padilla to design and develop a new lab for students in the Intermediate Design class to test real mechanical components. This report discusses the background and ideation process that lead to the development of the Educational Mechanical Breadboard for Transmission System Components (Machine Components Test). Additionally, detailed drawings, 3D modeling, testing plans, and analysis are included to show how the Machine Components Test design will work and be validated.
Effect Of Manufacturing Processes On The Loss Factor And Other Mechanical Properties Of Kenaf Fiber-Reinforced Composites, Brian P. Spackman
Effect Of Manufacturing Processes On The Loss Factor And Other Mechanical Properties Of Kenaf Fiber-Reinforced Composites, Brian P. Spackman
All Graduate Theses and Dissertations, Spring 1920 to Summer 2023
The characteristics essential for manufacturing parts and products are not well known for natural fiber-reinforced composite materials. Natural fibers display properties similar to glass fibers, and present a more environmentally friendly option for manufacturing composite materials. This research investigates various parameters in the manufacture of kenaf fiber-reinforced composites including cure time, density, matrix hardener ratio, surface treatment, and fiber length and examines the effect they have on mechanical properties of the composite material. Several samples were created and subjected to a vibrational test. Using known relationships, mechanical properties were extracted from the test results. Samples were found to exhibit repeatable …

Defeating Anisotropy In Material Extrusion 3d Printing Via Materials Development, Ángel Ramón Torrado Pérez
Open Access Theses & Dissertations
Additive Manufacturing technologies has been in continuous development for more than 35 years. Specifically, the later denominated Material Extrusion Additive Manufacturing (MEAM), was first developed by S. Scott Crump around 1988 and trademarked later as Fused Deposition Modeling (FDM). Although all of these technologies have been around for a while, it was not until recently that they have been more accessible to everyone. Today, the market of 3D printers covers all ranges of price, from very specialized, heavy and expensive machines, to desktop printers of only a few cubic inches in volume. Until recently, FDM technology had remained somewhat stagnant …

Predictive Methods For End Of Life Prognosis In Composites, Vamsee Vadlamudi
Theses and Dissertations
The long-term properties of continuous fiber reinforced composite materials are increasingly important as applications in airplanes, cars, and other safety critical structures are growing rapidly. The mechanical, electrical, and thermal properties of composite materials are altered by the initiation and accumulation of discrete fracture events whose distribution and eventual interaction defines the limits of design, such as strength and life. There is a correlation that exists between the long term behavior of those materials under combined mechanical, thermal, and electrical fields, and the functional properties and characteristics of the composite materials that requires a fundamental understanding of the material state …
