Developing a Heterogeneous Attenuation Model for Fiber Reinforced Thermoplastic Composites in the Kilohertz Region of the Ultrasonic Spectrum

Polymer Composites, Volume 47, Issue S2, Page S85-S95, 20 June 2026.
Acquisition, filtering and modeling by genetic programming (tree pattern) of the acoustic signal for fiber‐filled composites. ABSTRACT This study experimentally investigated the discrete phase contributions of fibers and entrapped air on the attenuation spectrum of a fiber‐filled thermoplastic composite and derives a mathematical expression for sound ...

Impact of grease churning on grease leakage, oil bleeding and grease rheology [PDF]

Tribology International, 2022
Grease performance is strongly determined by the properties and quantity of the grease after the churning phase in which grease reservoirs are formed. During this churning phase, macroscopic flow takes place, leading to drag forces dissipating energy in ...
