Study Of Permeability Testing Methods For Composite Laminates, Thomas S. Busse, Giannina Marie M. Yu
Study Of Permeability Testing Methods For Composite Laminates, Thomas S. Busse, Giannina Marie M. Yu
Materials Engineering
Permeability measurements are strong indicators of the effectiveness of evacuation channels within a composite prepreg. The effectiveness of these evacuation channels directly relates to the void content within a processed composite laminate. The goal of Toray Advanced Composites was to compare two permeability tests and determine which one was more reliable, accurate, and economical. The first permeability test method was the Cirrus method, designed by Cirrus Aircraft, a customer of Toray Advanced Composites. The second test was ASTM D8132, the standard method for permeability testing. Additionally, Toray sought to investigate the effect out-time had on the permeability of three different …
Composite Liftwalker For Shurouq, Daniel Martinez, Robert Boyd, Vikram Thridandam, Madeline Faase
Composite Liftwalker For Shurouq, Daniel Martinez, Robert Boyd, Vikram Thridandam, Madeline Faase
Mechanical Engineering
The following document describes the scope of our project and the methods we have deployed in designing and manufacturing a personalized composite LiftWalker for a young woman in Egypt named Shurouq. Our objective is to design a lightweight and durable LiftWalker to improve upon the current product of our project sponsor, Charlie Gutierrez. To accommodate Shurouq’s physical disabilities as well as the limits of transporting the device to her by plane, our team will need to alter the current product’s dimensions, materials, and structure. Through researching similar products and interviewing potential customers, we have compiled engineering specifications to guide the …
Cal Poly Prove Lab Endurance Car Composite Body Paneling Design, Emma Wheelock, Sarah Rutland, Noah Fisher, Brian Menard
Cal Poly Prove Lab Endurance Car Composite Body Paneling Design, Emma Wheelock, Sarah Rutland, Noah Fisher, Brian Menard
Mechanical Engineering
The Cal Poly Prototype Vehicles Laboratory (PROVE Lab) needs a body paneling design for their Endurance Car aeroshell which optimizes strength, weight and accessibility while minimizing complexity. Additionally, a low-complexity, accurate manufacturing process for the PROVE Lab Endurance Car aeroshell needs to be developed. PROVE Lab designed the shape of the aeroshell. The aeroshell will serve to reduce the aerodynamic drag on the car at high speed, and is not a structural component of the car. Due to the high-strength and lightweight nature of composites, PROVE Lab requests the senior project team investigate using composites for automotive body paneling applications. …
Numerical Methods For Predicting The Dynamic Crushing Response And Energy Absorption Of Composite Aluminum Honeycomb Sandwich Structures, Cody R. Volk
Master's Theses
Edgewise crushing responses of composite aluminum honeycomb sandwich structures were predicted using finite element analysis (FEA) software LS-DYNA by modeling the honeycomb as a material with anisotropic properties. The goal of the project was to develop a process for modeling the sandwich structure to rapidly iterate possible solutions for a safer workstation train table. Current workstation tables are too rigid and may cause injury or death in a head-on collision. Experimental compression tests were used to calibrate the aluminum honeycomb core with material type 26 (MAT 26, honeycomb). A published composite tensile test was used to validate the use of …
