Weighted Compositions [PDF]

open access: yesCanadian Mathematical Bulletin, 1961
By a composition of a positive integer n is meant a representation of n as a sum of one or more positive integers where the order of the summands is taken into account. Thus for example 4 has the eight compositions 4 = 3 + 1 = 1 +3 = 2 + 2 = 2 + 1 + 1 = 1 + 2 + 1 = 1 + 1 + 2 = 1 + 1 + 1 + 1.

Penetration impact testing of self-reinforced composites [PDF]

open access: yes, 2014
Penetration impact resistance is one of the key advantages of self-reinforced composites. This is typically measured using the same setup as for brittle fibre composites.

Material selection for automated dry fiber placement using the analytical hierarchy process

open access: yesAdvanced Manufacturing: Polymer & Composites Science, 2018
Dry fiber tapes have become an alternative to pre-impregnated tapes for automated fiber placement. However, their industrial adoption is inhibited by high upfront research and development cost.

Viscoelastic Fracture of Biological Composites

open access: yes, 2011
Soft constituent materials endow biological composites, such as bone, dentin and nacre, with viscoelastic properties that may play an important role in their remarkable fracture resistance.

« Composition, composition »…

open access: yesTransatlantica, 2013
Il s’agit de s’interroger sur ce qui se joue dans l’écriture littéraire et sur ce qui explique la difficulté qu’ont les non littéraires à saisir le travail de la langue et la composition esthétique de l’œuvre, lesquels assurent la puissance cognitive du texte littéraire et le distinguent fondamentalement des autres objets de fiction auquel il est ...

The influence of yarn fineness and number of yarn layers on in-plane shear properties of 3-D woven fabric

open access: yesAdvanced Composites Letters, 2020
The 3-D layer-to-layer angle-interlock woven fabric (LLAIWF) has good deformability on a complicated contour, which offers them a large application potential in the field of aerospace.

Novel hybrid flax reinforced supersap composites in automotive applications [PDF]

open access: yes, 2015
Flax fibre bio-epoxy composites have not found many commercial uses in structural applications on account of their lack of cost efficiency and high susceptibility to environmental changes. Non-woven flax mats were subjected to alkali, acetylation, silane

Virtual data-driven optimisation for zero defect composites manufacture

open access: yesMaterials & Design
Manufacture-induced defects are a critical issue in composites applications that result in high volumes of material waste and costly experimental trials to help mitigate this.

Performance enhancement of nylon/Kevlar fiber composites through viscoelastically generated pre-stress [PDF]

open access: yes, 2013
Kevlar-29 fibers have high strength and stiffness but nylon 6,6 fibers have greater ductility. Thus by commingling these fibers prior to molding in a resin, the resulting hybrid composite may be mechanically superior to the corresponding single fiber ...

Washing load influences the microplastic release from polyester fabrics by affecting wettability and mechanical stress

open access: yesScientific Reports, 2021
Microplastics released from textiles during the washing process represent the most prevalent type of microparticles found in different environmental compartments and ecosystems around the world.
