Numerical and experimental analyses of resin infusion manufacturing processes of composite materials [PDF]

open access: yesJournal of Composites Materials 46, 13 (2012) 1617-1631, 2012
Liquid resin infusion (LRI) processes are promising manufacturing routes to produce large, thick, or complex structural parts. They are based on the resin flow induced, across its thickness, by a pressure applied onto a preform/resin stacking. However, both thickness and fiber volume fraction of the final piece are not well controlled since they result

Application of the TPB Wavelength Shifter to the DEAP-3600 Spherical Acrylic Vessel Inner Surface [PDF]

open access: yes2017 JINST 12 P04017, 2017
DEAP-3600 uses liquid argon contained in a spherical acrylic vessel as a target medium to perform a sensitive spin-independent dark matter search. Argon scintillates in the vacuum ultraviolet spectrum, which requires wavelength shifting to convert the VUV photons to visible so they can be transmitted through the acrylic light guides and detected by the

Phase Behavior of Polyelectrolyte Block Copolymers in Mixed Solvents [PDF]

open access: yes, 2008
We have studied the phase behavior of the poly(n-butyl acrylate)-b-poly(acrylic acid) block copolymer in a mixture of two miscible solvents, water and tetrahydrofuran (THF). The techniques used to examine the different polymers, structures and phases formed in mixed solvents were static and dynamic light scattering, small-angle neutron scattering ...

Thermal Conductivities and Mechanical Properties of Epoxy Resin as a Function of the Degree of Cross-linking [PDF]

open access: yesarXiv, 2021
Epoxy resins are widely used polymer matrices for numerous applications. Despite substantial advances, the molecular-level knowledge-base required to exploit these materials to their full potential remains limited. A deeper comprehension of structure/property relationships in epoxy resins at the molecular level is critical to progressing these efforts.

Flexural Resistance and Impact Resistance of High-Impact Acrylic Resin with Addition of TiO2-Al2O3 Nanoparticles

open access: yesNano Biomedicine and Engineering, 2018
The chemical modification of conventional acrylic resin by butadiene-styrene rubber to get high-impact acrylic resin has not been completely effective due to its potential bad influence on the resistance of bending or flexural and also the toughness of ...

Specific heat, thermal conductivity, and magnetic susceptibility of cyanate ester resins --- An alternative to commonly used epoxy resins [PDF]

open access: yesCryogenics 95, 76--81 (2018), 2018
In low temperature experiments, resins have many applications as glues or thermal and electrical insulators. Cyanate ester resins (CEs) are a high-temperature compatible thermoset resin whose glass-transition temperature $T_g$ is ~300 $^\circ$C. Recently, we found that CEs also withstand low temperatures without microcracking by measuring $^4$He ...

Monitoring the resin infusion manufacturing process under industrial environment using distributed sensors [PDF]

open access: yesJournal of Composite Materials 46, 6 (2012) 691-706, 2012
A novel direct approach to detect the resin flow front during the Liquid Resin Infusion process under industrial environment is proposed. To detect the resin front accurately and verify the results, which are deduced from indirect micro-thermocouples measurements, optical fiber sensors based on Fresnel reflection are utilized.
