Inverse Analysis to Determine Hygrothermal Properties in Fiber Reinforced Composites
Fiber-reinforced composite laminates are often used in severe environments such as high temperature and humidity conditions. Therefore, it is of practical interest to establish a simple but robust method to determine material properties that define the hygrothermal behavior of composites under various conditions. In this article a novel inverse analysis approach is presented to identify the dif...
متن کاملNon-Destructive Testing Evaluation of Low Velocity Impact Damage in Carbon Fiber-Reinforced Laminated Composites
Fiber-reinforced laminated composite materials are widely used in aircraft, modern vehicles and light-weight structures. With their high elastic modulus, high strength, and capability of being tailored for a several applications, these materials offer definite advantages compared to more traditional structural materials. However, their behavior under impact is of concern since those events may ...
متن کاملAutonomic healing of low-velocity impact damage in fiber-reinforced composites
In this study autonomic self-healing of impact damage in composite materials is shown using a microencapsulated healing agent. The components for self-healing, urea–formaldehyde microcapsules containing dicyclopentadiene (DCPD) liquid healing agent and paraffin wax microspheres containing 10 wt% Grubbs’ catalyst, have been successfully incorporated in a woven S2-glass-reinforced epoxy composite...
متن کاملFinite Element Analysis of Low Velocity Impact on Carbon Fibers/Carbon Nanotubes Reinforced Polymer Composites
An effort is made to gain insight on the effect of carbon nanotubes (CNTs) on the impact response of carbon fiber reinforced composites (CFRs) under low velocity impact. Certain amount of CNTs could lead improvements in mechanical properties of composites. In the present investigation, ABAQUS/Explicit finite element code (FEM) is employed to investigate various damages modes of nano composites ...
متن کاملCharacterization of fiber distribution in steel fiber reinforced cementitious composites with low water-binder ratio
Image analysis technique is introduced to characterize fiber distribution in steel fiber reinforced cementitious composites. Through cutting and polishing of specimen, image acquisition of specimen surface, extraction of fiber feature, and measurement of related fiber parameters, i.e., dispersion coefficient and orientation factor, are given to quantitatively analyze fiber distribution. Effects...
