Multi-material rail pad and method for manufacturing same
Véronique Michaud, John Christopher Plummer, Holger Frauenrath, Joël Cugnoni, Oguzhan Oguz, Adrien Julien Demongeot
The invention relates to a rail pad (10, lOa-v, 10α-η) comprising: a) a pad matrix (1) comprising a first material and b) at least one damping element (2) at least partially encapsulated or embedded in the pad matrix (1), said damping element (2) comprisin ...
2022Mechanical reinforcement and memory effect of strain-induced soft segment crystals in thermoplastic polyurethane-urea elastomers
Nicolas Candau, Oguzhan Oguz, Adrien Julien Demongeot
An amorphous poly(urethane-urea) copolymer composed of 70 wt% poly(ethylene oxide) (PEO) soft segments (SS) (Mw = 2000 g mol−1) and 30 wt% cycloaliphatic hard segments (HS) was subjected to in-situ X-Rays during tensile deformation. Mechanical hardening at ...
2021Stiff, Strong, Tough, and Highly Stretchable Hydrogels Based on Dual Stimuli-Responsive Semicrystalline Poly(urethane–urea) Copolymers
Nicolas Candau, Oguzhan Oguz, Adrien Julien Demongeot
There has been a considerable interest in developing stiff, strong, tough, and highly stretchable hydrogels in various fields of science and technology including biomedical and sensing applications. However, simultaneous optimization of stiffness, strength ...
2021Poly(lactide)/cellulose nanocrystal nanocomposites by high-shear mixing
Véronique Michaud, Nicolas Candau, Oguzhan Oguz, Adrien Julien Demongeot, Mehmet Kerem Citak, Fatma Nalan Cetin
There is currently considerable interest in developing stiff, strong, tough, and heat resistant poly(lactide) (PLA) based materials with improved melt elasticity in response to the increasing demand for sustainable plastics. However, simultaneous optimizat ...
WILEY2020Strain and filler ratio transitions from chains network to filler network damage in EPDM during single and cyclic loadings
Chains and filler network damage were investigated during single and multiple cycles on a series of vulcanized EPDM containing various filler contents. In both series of experiments, a strain and a filler ratio transitions for damage mechanisms were identi ...
2020Composition and method for the preparation of sheets, films, fibers, and molded parts
Holger Frauenrath, Daniel Görl, Oguzhan Oguz
The invention describes a composition containing a) a functionalized polymer (10) that comprises at least one polyester segment (13) and at least one, in particular at least two, polymer aggregating segment (11, 12) capable of forming non-covalent bonds ba ...
2020Heat source and voiding signatures of Mullins damage in filled EPDM
The thermomechanical coupling of Mullins damage in filled EPDM has been investigated by analysing the self-heating via Infrared thermography (IR) and the voiding fraction by Digital Image Correlation (DIC). The volumetric strain measured during the rubber ...
ELSEVIER SCI LTD2020A Sustainable Approach to Produce Stiff, Super-Tough, and Heat-Resistant Poly(lactic acid)-Based Green Materials
Nicolas Candau, Oguzhan Oguz, Mehmet Kerem Citak, Fatma Nalan Cetin
Circumventing inherent embrittlement, poor heat resistance, and melt elasticity of poly(lactic acid) (PLA) without compromising its remarkable stiffness and strength has become a particular challenge in polymer science due to increasing demand for green ma ...
AMER CHEMICAL SOC2019Strain-induced network chains damage in carbon black filled EPDM
This paper presents an experimental method to follow in-situ the chains network alteration of filled vulcanized rubbers induced by deformation. Macroscopic damage is first investigated on a series of EPDM by quantifying void fraction via Digital Image Corr ...
ELSEVIER SCI LTD2019Tuning Interaction Parameters of Thermoplastic Polyurethanes in a Binary Solvent To Achieve Precise Control over Microphase Separation
Thermoplastic polyurethanes (TPUs) are designed using a large variety of basic building blocks but are only synthesized in a limited number of solvent systems. Understanding the behavior of the copolymers in a selected solvent system is of particular inter ...
