Numerical and Experimental Investigation on Bending Behavior for High-Performance Fiber Yarns Considering Probability Distribution of Fiber Strength

open access: yesTextiles, 2023
The performance of fiber-reinforced composite materials is significantly influenced by the mechanical properties of the yarns. Predictive simulations of the mechanical response of yarns are, thus, necessary for fiber-reinforced composite materials.

Mechanical properties of hand-making polyester composites [PDF]

open access: yes, 2018
The aim of this paper is to determine the effect of arrangement of fibreglass fabric plies in a polymer composite on a strength. Based on the experimental results, the real effect of plies arrangement and their most favourable configuration with respect ...

Counting Composites [PDF]

open access: yesAustralasian Journal of Philosophy, 2021
I defend the thesis that Composition Entails Identity (CEI): that is, a whole is identical to all of its parts, taken together. CEI seems to be inconsistent, since it seems to require that the parts of a whole possess incompatible number properties (for instance, being one thing and being many things).

Effective Action of Composite Fields for General Gauge Theories in BLT-Covariant Formalism [PDF]

open access: yes, 1996
The gauge dependence of the effective action of composite fields for general gauge theories in the framework of the quantization method by Batalin, Lavrov and Tyutin is studied. The corresponding Ward identities are obtained.

POSSIBILITIES OF 3D MACHINING OF MATERIALS BY ABRASIVE WATER JETS

open access: yesGeoScience Engineering, 2019
Machining of materials through the classical way, i.e. using conventional tools for turning, drilling, milling, grinding and polishing, has some limits that can be overcome applying an abrasive water jet (AWJ).

Effects of Hydroxyl Treatment on Atomic Resistance Property of Hexagonal Boron Nitride Film

open access: yesCailiao gongcheng, 2018
Surface hydroxyl treatment of hexagonal boron nitride (hBN) was performed in sodium hydroxide aqueous solution. With hBN, hBN-OH and nanofibrillated cellulose fibers (NFC), flexible free-standing high-content BN films were fabricated through vacuum ...

Lambda Boo stars with composite spectra [PDF]

open access: yes, 2004
We examine the large sample of lambda Boo candidates collected in Table 1 of Gerbaldi et al. (2003) to see how many of them show composite spectra. Of the 132 lambda Boo candidates we identify 22 which definitely show composite spectra and 15 more for ...
