Evolution of physico-chemical and mechanical properties of bonded epoxy assemblies during hygrothermal cyclic aging

open access: yesMechanics & Industry, 2023
This work investigates the hygrothermal cyclic aging of epoxy-based bonded assemblies. The focus is given here to severe long-term environmental conditions. The aging procedure is performed between 70° C with a relative humidity of 90% and −40° C without

Longitudinal Compressive Property of Three-Dimensional Four-Step Braided Composites after Cyclic Hygrothermal Aging under High Strain Rates [PDF]

open access: yesApplied Sciences, 2020
The longitudinal compressive behavior of the three-dimensional four-step braided composites after cyclic hygrothermal aging was investigated using a split Hopkinson pressure bar (SHPB) apparatus under high strain rates (1100~1250 s−1, 1400~1600 s ...

Effects of Hygrothermal Aging and Cyclic Compressive Loading on the Mechanical and Electrical Properties of Conductive Composites. [PDF]

open access: yesPolymers (Basel), 2022
Conductive polymers and their composites have been widely applied in different applications, including sensing applications. Herein, we constructed a conductive composite of polypropylene, carbon black, and multi-walled carbon nanotubes (PP/CB/MWCNTs) to experimentally study its sensing behaviors in a humid thermal environment. The as-synthesized PP/CB/

Why cyclic hygrothermal ageing modifies the transverse mechanical properties of a unidirectional epoxy-flax fibres composite? [PDF]

open access: yesIndustrial Crops and Products, 2021
Abstract The development of composites based on plant fibres has considerably grown in last decades; however, their high sensitivity to moisture limits their use in structural applications. The objective of this study is to determine and understand the impact of moisture variations during one-year cyclic hygrothermal ageing i.e.

Hygrothermal exposure and residual strength after cyclic loading on epoxy composites reinforced with sisal fibers

open access: yesPolymer Testing, 2023
The fatigue behavior of epoxy/sisal composites with hygrothermal exposure was investigated. However, their mechanical characterization under cyclic loading associated with aging from hygrothermal exposure is necessary to expand their use in consumer ...
