Identification of the through-thickness rigidities of a thick laminated composite tube [PDF]

open access: yesComposites Part A: Applied Science and Manufacturing, 2006
In this paper, a novel experimental procedure is carried out for providing all the through-thickness rigidities of a thick glass-epoxy laminated ring cut from a tube, using only one diametral compression test. The procedure requires first to measure the strain field over a predefined area of the lateral surface of the ring coupon, and then to process ...

Thick-Section Epoxy Composites

open access: yes, 2021
Thick-section composites (TSC) are extensively demanded in many fields, such as aerospace, wind energy, and oil and gas industries. However, the manufacturing process of thick-section thermoset composites (TSSC) encounters significant complexities, such as variations of nonuniform resin flow, exothermal reaction and curing, and dimensional stability ...

Fiber association and network formation in PLA/lignocellulosic fiber composites. [PDF]

open access: yes, 2013
PLA composites were prepared in an internal mixer with a lignocellulosic fiber having relatively large aspect ratio. Fiber content changed between 0 and 60 vol% and the homogenized material was compression molded to 1 mm thick plates.

From mice to humans—divergent strategies for intestinal homeostasis and regeneration

open access: yesFEBS Letters, EarlyView.
Recent advances such as organoid genome editing, xenotransplantation, imaging, and whole‐genome sequencing have enabled direct studies of human intestinal stem cells (ISCs). These studies reveal species‐specific features, including slower ISC proliferation, distinct injury responses, slower somatic mutation accumulation in humans, and an inverse ...

An experimental and computational investigation of embedded wrinkle’s impacts on the compressive responses of thick unidirectional glass fiber-reinforced composites

open access: yesMaterials & Design, 2023
In thick unidirectional glass fiber-reinforced composites, the out-of-plane embedded wrinkle flaws have a major impact on compressive failure, which should be taken into account and assessed during the design, manufacturing, and inspection phases.
