1. 1. Investigating In-plane Shear Behaviour of Uncured Unidirectional Prepreg Tapes

   University essay from KTH/Lättkonstruktioner

   Author : Ming Kai Chea; [2019]
   Keywords : ;

   Abstract : 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.

3. 2. An Investigation of the Adhesive Interaction between Polyethylene and Silicone with DMA and AFM

   University essay from Lunds universitet/Centrum för analys och syntes

   Author : Joel Falk; [2019]
   Keywords : Atomic Force Microscope; Adhesion; Characterization; Dynamic Mechanical Analysis; Injection Molding; Polyethylene; Polymer; Silicone; Test method development; Materials chemistry; Materialkemi; Technology and Engineering;

   Abstract : Stickiness between materials can be a challening task when dealing with the complex interactions and processes related to packaging engineering. Part of the problem is that many factors like temperature, pressure, surface treatment as well as surface roughness all could play a part in contributing to the stickiness between materials.

4. 3. Furnace Brazing of AlSi-coated and Uncoated 22MnB5 Steel at Austenite Temperatures

   University essay from KTH/Lättkonstruktioner

   Author : Adam Häggqvist; [2015]
   Keywords : ;

   Abstract : By continued advances in mechanical strength of press hardened boron alloyed steel (22MnB5) weight savings can be achieved by the use of less material. However, with reduced material thickness stiffness problems such as buckling arises and the high strength of the material can’t fully be taken advantage of. READ MORE

5. 4. Evaluation of Bond Strength between Overlay and Substrate in Concrete Repairs

   University essay from KTH/Betongbyggnad

   Author : Keivan Neshvadian Bakhsh; [2010]
   Keywords : Bond strength; Pull-off test; Slant shear test; Concrete repair;

   Abstract : Good bond strength between overlay and substrate is a key factor in performance of concrete repairs. This thesis was aimed at studying the evaluation of bond strength between repair material and substrate at the interface. Many factors such as surface roughness, existence of micro cracks, compaction, curing etc influence the bond strength. READ MORE
