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 Analysis of Composite Materials

2004
Abstract Voids in fiber-reinforced composite materials are areas that are absent of the composite components: matrix (resin) and fibers. Voids have many causes but generally can be categorized as voids due to volatiles or as voids that result from entrapped air. This article describes the analysis of various types of voids.

Void formation in short‐fiber thermoplastic composites

Polymer Composites, 1989
AbstractVoids, or bubbles, are formed in short‐fiber thermoplastic composites because of entrapment of air in the compounding and melt flow processing steps and as a result of uneven shrinkage due to temperature gradients involved in the solidification step by cooling.

Effect of void morphology on void facilitated plasticity in irradiated Cu/Nb metallic nanolayered composites

Journal of Nuclear Materials, 2022
Abstract Voids are common radiation-induced defects in nuclear materials and produce detrimental effects on mechanical properties. The influence of a pre-existing void on mechanical behavior has been investigated in single crystals, but the effects of void located at bimetal interfaces on the dislocation nucleation mechanisms and associated ...
