Modelling the effect of yarn twist on the tensile strength of unidirectional plant fibre yarn composites

open access: yes, 2012
The true structural potential of plant fibres as reinforcing agents can only be realized when the highest reinforcement efficiency is employed. Hence, aligned unidirectional plant fibre composites (PFCs) are of interest.

A Numerical–Experimental Approach for Multi‐Matrix Fiber‐Reinforced Plastics Characterization Using Finite Element Model Updating

open access: yesAdvanced Engineering Materials, EarlyView.
A numerical–experimental framework is developed for characterizing multi‐matrix fiber‐reinforced polymers (MM‐FRPs) combining epoxy and polyurethane matrices. Harmonic bending tests are integrated with finite element model updating (FEMU) to simultaneously identify elastic and viscoelastic material parameters.

Predicting torque of worsted singles yarn using an efficient radial basis function network-based method [PDF]

open access: yes, 2007
The torque in single-spun yarns is an inherent property of the twisting and bending of staple fibres during the formation of yarn combined with the effect of applied tension on the yarn.

A Simplified Laminar Flow Model for the Pultrusion of Glass Fiber/Polyethylene Terephthalate Commingled Yarns

open access: yesAdvanced Engineering Materials, EarlyView.
A simplified thermoplastic pultrusion model is developed to predict thermal fields in glass fiber/polyethylene terephthalate (GF/PET) composites with reduced computational cost. By combining effective material homogenization, validation against literature data, and Gaussian‐process‐based optimization, the study reveals how heating limits, pulling speed,

Is an Apple an Orange? A Large Language Model Benchmark for Candidate Term Extraction and Subclass Decisions Against Upper Ontologies in Engineering and Materials Science

open access: yesAdvanced Engineering Materials, EarlyView.
Building machine‐readable vocabularies for materials science is slow, expert‐driven work. This study benchmarks 13 large language models on two of its first steps: finding candidate terms in engineering articles and deciding where they belong in a class hierarchy.

Effect of repeated winding on carded ring cotton yarn properties

open access: yes, 2011
In this study, ten carded ring spun cotton yarns were subjected to windings. Yarn hairiness, fineness, unevenness and tensile properties were then examined. Results showed that the majority of the increased yarn hairiness occurred at the beginning cycles

The Spinning Experience: Hand Spinning as Pedagogy, Experiential Learning, and Physical Output

open access: yesKULA
While the spinning wheel, known in many Indian languages as the charkha, continues to be an integral part of modern India's imagination (Gandhi made it a symbol of self-reliance and freedom), very few people have actually seen the object, leave alone ...

A Lightweight Procedural Layer for Hybrid Experimental–Computational Workflows in Materials Science

open access: yesAdvanced Engineering Materials, EarlyView.
We unveil a prototype hybrid‐workflow framework that fuses automatedcomputation with hands‐on experiments. Built atop pyiron, a lightweight, parameterized layer translates procedure descriptions into executable manual steps, syncing instrument settings, human interventions, and data capture in real‐time today.

Electrically Stable Carbon Nanotube Yarn Under Tensile Strain

open access: yes, 2017
We report a highly stable electrical conductance of a compact and well-oriented carbon nanotube yarn under tensile strain. The gauge factor of the yarn was found to be extremely small of approximately 0.15 thanks to the improvements in the dry spinning ...

A multi-scale yarn appearance model with fiber details

open access: yesComputational Visual Media
Rendering cloth realistically has always been a challenge due to its intricate structure. Cloth is made up of fibers, plies, and yarns, and previous curve-based models, while detailed, were computationally expensive and inflexible for large pieces of ...
