Effects of consolidation processing parameters on the surface morphology and void content of braided thermoplastic composite tubes

Functional Composites and Structures, 2021
In this study, the consolidation process of radial-type braided carbon fiber reinforced polyetherketoneketone (CF/PEKK) thermoplastic composite tubes was investigated.

Void content of polypropylene/carbon fiber wet‐laid nonwoven composites: Effect of fiber content and molding conditions, and void elimination mechanism

Polymer Composites, 2023
AbstractVarious wet‐laid nonwoven composites have been well‐developed in recent decades. However, studies that systematically investigate the factors affecting the void content of wet‐laid nonwoven composites are still missing. This paper aims to study the factors affecting the void content of wet‐laid nonwoven composites and propose a mechanism for ...

Critical Void Content for Thermoset Composite Laminates

Journal of Composite Materials, 2006
An experimental program to characterize the effect of voids on the strength of composite laminates is presented. The adequacy of a fracture criterion to represent the experimental data for the effect of voids on the flexure strength, tensile strength, and interlaminar shear strength of composite laminates is assessed.

Critical Void Content for Polymer Composite Laminates

AIAA Journal, 2005
An experimental program to characterize the effect of voids on the strength of composite laminates is presented, and the adequacy of a fracture criterion to represent the experimental data for the effect of voids on the compressive and interlaminar shear strength of composite laminates is assessed.

Void Content Prediction in Two-Size Aggregate Mixes

Journal of Testing and Evaluation, 1981
Abstract The purpose of this research was to develop a method to predict the interparticle voids in combinations of two sizes of aggregates. Theoretical concepts and predictions preceded the experimental work. Statistical techniques and computers were used in the design of the experiment and in the analysis of the data.

Bulk modulus determination of solid propellant void content

Journal of Spacecraft and Rockets, 1985
Nitrate ester decomposition in propellant systems leads to a slow buildup of internal gas pressure which potentially can create internal porosity, void formation, and fracture. While related experimental techniques currently available can provide information on ultimate propellant fracture by monitoring gross property changes, few procedures were ...

Evaluation of compressive strength and void content of resin based dental composites

, 2020
Resin based dental composites are quite popular for tooth restoration. In this article, BisGMA and TEGDMA were mixed to make resin matrix. For photo-polymerization, Camphorquinone was used and DMAEA was used as accelerator.
