Failure Criterion for Two-Ply Plain-Weave CFRP Laminates
We present an experimentally-based failure criterion for symmetric two-ply plain-weave laminates of carbon-fiber reinforced plastic. The criterion is formulated in terms of six force and moment stress resultants and consists of a set of three inequalities, related to in-plane, bending, and combined in-plane and bending types of failure. All failure parameters in the criterion are measured direc...
متن کاملImpact Damage Detection of Toughened CFRP Laminates with Time Domain
Laminated Carbon Fiber Reinforced Polymer (CFRP) composites are very effective in weight saving in aeronautical structural components. For these laminated CFRP structures, it is, however, difficult to detect damage such as delamination, matrix cracks, and local fiber breakages caused by low velocity impact loading In the previous study in 2009, Time Domain Reflectometry (TDR) method was applied...
متن کاملUltrasonic NDE Techniques for Impact Damage Inspection on CFRP Laminates
This study investigates the different types of ultrasonic inspection, when applied to assess the impact damage in Carbon Fiber Reinforced Plastic CFRP laminates. The study surveys the two most used ultrasonic testing approaches first; namely the pulse-echo and the through-transmission modes. Then, the manuscript discusses and analyzes the enhanced ultrasonic testing methods that use the polar s...
متن کاملIn-Plane Effective Thermal Conductivity of Plain-Weave Screen Laminates
A simple-to-fabricate woven mesh, consisting of bonded laminates of two-dimensional plain-weave conductive screens is described. Geometric equations show that these porous matrices can be fabricated to have a wide range of porosity and specific surface area, . A heat transfer model is developed. It shows that the laminates can have a highly anisotropic thermal conductivity vector, with in-plane...
متن کاملIn-plane Effective Ther Mal Conductivity of Plain Weave Screen Laminates with Arbitrary Weave Parameters
A conductive laminate consisting of stacked two-dimensional plain-weave screen with an arbitrary weave angle is described. Similar to orthogonal screen laminates, these porous matrices can be fabricated to have a wide range of porosity, ε and specific surface area, ß; and the structure can have a highly anisotropic thermal conductivity vector, with in -plane effective thermal conductivities ran...
