Recycling Of Cured Carbon Fiber/Epoxy Resin Laminated Composites Scraps: Processing And Characterization, Khaled Mohammed Al Harmoodi
Recycling Of Cured Carbon Fiber/Epoxy Resin Laminated Composites Scraps: Processing And Characterization, Khaled Mohammed Al Harmoodi
Theses
The concept of reinforced composites came decades ago from the need to fabricate high-strength, heat-resistant, wear-resistant, and low-density materials. The polymer matrix composites offer a wide range of applications due to the collaborative nature of the functional fillers and polymers present. Towards the twenty-first century, the aviation industry flourished due to flying being the preferred way of travel across states and countries. With such a massive demand for air transport, there is an equally parallel demand for the production of aircraft components. This study aims to reuse the waste of uncured composite prepreg scraps from the ply-cutting manufacturing process in …

Honors Capstones
It is no secret that lifting heavy objects is one of the premier causes of workplace injury, and the modern worker needs help to remain healthy. Workers need something they always have with them that makes their work safer as well as easier; our solution is an active lift-assist exoskeleton. The proposed exoskeleton design includes a military backpack exoskeleton frame, on which two actuators pull cables attached to end effectors that the operator will be holding. This system can adjust to conform to a wide variety of operator sizes, without restricting any of their range of motion. This leads to …

Mechanical Engineering
In this report, the Featherweight Cycles design team puts forth the scope and overview of their design project, discusses background research and competitor analysis, and presents the project’s final design and manufacturing plans. The overall goal of this project is to fabricate and compete in the Fluid Power Vehicle Challenge, hosted by the National Fluid Power Association. To better define the design process, the team researched previous year’s designs from Cal Poly, as well as winning designs from the last two years to form a baseline of knowledge about competing schools’ designs. After researching multiple design paths, Featherweight Cycles chose …
Experimental Setup Of A Rapid Compression Machine For Spark Ignition Studies, Daniel Llaguno
Experimental Setup Of A Rapid Compression Machine For Spark Ignition Studies, Daniel Llaguno
Electronic Theses and Dissertations
The main objective of this thesis is to document the design and development of a rapid compression machine (RCM). A series of tests were performed to verify the operation of the system using the compression of air. Finally, an experiment was conducted to validate the auto-ignition temperature of DME under HCCI mode. Based on the first version of the RCM, improvements were made to speed up the compression process, and to create the conditions required for the auto-ignition of a DME-air mixture. The inlet diameter of the pneumatic actuation cylinder was increased to reduce the choking effect of the air …
