Physical, Mechanical, and Thermal Properties and Characterization of Natural Fiber Composites Reinforced Poly(Lactic Acid): Miswak (Salvadora Persica L.) Fibers

open access: yesInternational Journal of Polymer Science, 2022
7000 years ago, miswak fiber (MF) was used as a toothbrush for oral care. However, since the emergence of plastic materials, it monopolized the oral care industry.

Effect of three-directional orthogonal preform weaving parameters on properties of C/C composites

open access: yesCailiao gongcheng, 2022
Taking the three-directional orthogonal preform with different Z-direction fiber distance as the research object, the carbon/carbon (C/C) composites were prepared by the combination of chemical vapor infiltration and resin impregnation, and the effect of

Progress in high strength intermediate modulus carbon fiber and its high toughness resin matrix composites in China

open access: yesCailiao gongcheng, 2020
High strength intermediate modulus carbon fiber composites are still the main aviation composites in the world at present and for a long time to come. In recent year, based on the experience of high-strength carbon fiber composites, the industrialization

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 ...

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 ...

Microstructure and densification of 3D weaving preform

open access: yesCailiao gongcheng, 2021
The carbon fiber preform is the skeleton of the carbon/carbon material. During the densification process,the pores of the preform is filled by the matrix carbon to form a carbon/carbon composite material.

Cardinal Composition

open access: yesErkenntnis, 2022
AbstractThe thesis of Weak Unrestricted Composition says that every pair of objects has a fusion. This thesis has been argued by Contessa (Analysis 72(3):455–457, 2012) and Smith (Erkenntnis 84(1):41–55, 2019) to be compatible with the world being junky and hence to evade an argument against the necessity of Strong Unrestricted Composition proposed by ...

Weinberg’s Compositeness

open access: yesSymmetry, 2022
Nearly 60 years ago, Weinberg suggested a criterion for particle “compositeness”, which has acquired a new life with the discovery of new, exotic hadrons. His idea resonates with model-based intuition. I discuss the role it plays in the context of another of Weinberg’s creations, the model-independent framework of effective field theories.
