Electrical control of the linear optical properties of particulate composite materials [PDF]

open access: yesProc. R. Soc. A (2007) 463, 583-592, 2006
The Bruggeman formalism for the homogenization of particulate composite materials is used to predict the effective permittivity dyadic of a two-constituent composite material with one constituent having the ability to display the Pockels effect. Scenarios wherein the constituent particles are randomly oriented, oriented spheres, and oriented spheroids ...

Impact Performance of Three-dimensional Woven Composites with Novel Binding Yarn Patterns

open access: yesJournal of Natural Fibers, 2022
This research offered an experimental examination of the effect of binder yarns, and 3D woven patterns on impact (Charpy and drop weight impact), and compression after impact (CAI) performance of seven (07) different kinds of 3D woven jute/green epoxy ...

Effect of PEEK Particles on Physiomechanical Behavior of Carbon/Epoxy Composite

open access: yesInternational Journal of Polymer Science, 2022
The inherently brittle nature and the susceptibility to impact damage hinder the use of carbon/epoxy composite in some areas. In this study, poly ether ether ketone (PEEK) microparticles were incorporated to increase the resistance to delamination and ...

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.

Oxidation behaviors of carbon fiber reinforced multilayer SiC-Si3N4 matrix composites

open access: yesJournal of Advanced Ceramics, 2022
Oxidation behaviors of carbon fiber reinforced SiC matrix composites (C/SiC) are one of the most noteworthy properties. For C/SiC, the oxidation behavior was controlled by matrix microcracks caused by the mismatch of coefficients of thermal expansion ...
