Determination of shift factor for long-term life prediction of carbon/fiber epoxy composites using the time-temperature superposition principle

Functional Composites and Structures, 2022
This study presents the way to determine the shift factor for predicting the long-term behavior of a carbon fiber/epoxy composite using the time-temperature superposition (TTS) principle. We conducted the multi-frequency, creep TTS, and stress relaxation

Time-Temperature Superposition Based Accelerated Aging Method for Packaged MEMS Resonators

2022 Joint Conference of the European Frequency and Time Forum and IEEE International Frequency Control Symposium (EFTF/IFCS), 2022
SummaryThis manuscript introduces a new methodology to accelerate and predict stress-related aging in encapsulated MEMS resonators. This approach builds upon the time-temperature superposition principle that, in linear viscoelastic materials, relates the

Time-temperature superposition of flexural creep response of carbon fiber PEKK composites manufactured using different prepreg stacking sequence

Journal of Thermoplastic Composite Materials, 2021
In this work, the long-term creep response of high-performance carbon fiber PEKK (CF/PEKK) composites was evaluated by performing extrapolated short-term flexural creep tests at various temperatures.

Time-Temperature Superposition of the Dissolution of Silk Fibers in the Ionic Liquid 1-Ethyl-3-methylimidazolium Acetate.

Biomacromolecules, 2021
This study investigated the dissolution of silk multifilament fibers in the ionic liquid 1-ethyl-3-methylimidazolium acetate. The dissolution process was found to create a silk composite fiber, comprising undissolved silk multifilaments surrounded by a ...

Long-term creep behaviour of E-glass/epoxy composite: Time-temperature superposition principle

Plastics, Rubber and Composites: Macromolecular Engineering, 2020
Creep behaviour of an epoxy matrix composite with a similar arrangement of composites used in a root joint of a wind turbine blade is investigated in this research. The vacuum infusion process was used to manufacture the composite.
