1. Rapid prototyping with fiber composites - Manufacturing of an amphibious UAV
Master-uppsats, KTH/LättkonstruktionerSammanfattning : Rapid prototyping has in the last few years gained an ever increasing central role in projects thanks to its agile benefits. Because of that, boundaries regarding what can be accomplished can be pushed and new techniques for achieving goals can be explored at a reasonable cost. LÄS MER
2. Commercial Aircraft Wing Structure : - Design of a Carbon Fiber Composite Structure
Kandidat-uppsats, KTH/Skolan för teknikvetenskap (SCI)Sammanfattning : This project explores the classical wing structure of an commercial aircraft for an all carbon fiber reinforced polymer unmanned aerial vehicle(UAV). It is part of a collaborative work consisting of several groups researching different parts of the aircraft. LÄS MER
3. Virtual characterization of composite materials for aero-engine components
Master-uppsats, Luleå tekniska universitet/Institutionen för teknikvetenskap och matematikSammanfattning : Since its beginnings, the aerospace industry has been interested in lowering the weight of aircraft. Moving from performance and economic drivers to environmental design parameters, the weight has continuously been a major focus for this industry. LÄS MER
4. Consolidation and Forming of Aerospace Graded Composite Materials : An experimental study of prepreg characteristics
Master-uppsats, KTH/LättkonstruktionerSammanfattning : The topic of this project is an experimental study of prepreg characteristics, such as tack, consolidation and temperature sensitivity during forming. The aim has first been tounderstand how the material reacts during different manufacturing processes. LÄS MER
5. Investigating In-plane Shear Behaviour of Uncured Unidirectional Prepreg Tapes
Master-uppsats, KTH/LättkonstruktionerSammanfattning : Steering of prepreg tows in an automated fibre placement (AFP) process allows geodesic layup trajectory over a doubly-curved surface, as well as the potential to improve the efficiency of composite structures by tailoring their stiffness. However, defects (such as out-of-plane buckling and tow pull off) are commonly generated when the steering radius exceeds a critical limit, which impact the mechanical properties of the finished product.
