To investigate and evaluate the effect of void features on mechanical performance composite materials, it is important to be able manufacture samples with a range controlled content. A criterion less than 2% porosity typically acceptable for industry. However, content above below this range, as voids are unevenly distributed in parts, so there likely local concentrations higher some sections structures. In paper, novel manufacturing process that allows panels contents manufactured manner...
The upward trend for the use of electrical power on state-of-the-art aircraft is resulting in significant change to design system architectures and protection systems these platforms. There a pull from aerospace industry integrate with aircraft's structural materials form an embedded system, reducing need bulky cable harnesses. This directly impacts fault response ground faults ultimately development appropriate systems. Such include composites such as carbon fiber reinforced polymer (CFRP)....
The presence of voids in composite materials reduces the material's strength, particularly matrix-dominated properties such as short beam shear (SBS) strength. Until now there has been no satisfactory way to reliably predict effect on SBS Instead, a reliance using average void content combined with extensive testing assess linear reduction strength increasing determine 'knock-down' factor. Here, reduced cross-sectional area is used laminates containing voids. A detailed characterisation...
This article reports on the work of European Structural Integrity Society Technical Committee 4 (ESIS TC4) and its activities in development test protocols for peel fracture. Thirteen laboratories have been working methods ESIS TC4 since 1997 their are ongoing. The aim is to develop robust credible determination adhesive fracture toughness by tests. Several geometric configurations used, namely, multi-angle fixed arm peel, T-peel, roller assisted form a mandrel test. starting point an...
A mandrel peel test is established for measuring the adhesive fracture toughness of a metal/rubber-toughened epoxy laminate system. By adopting an energy balance analysis it possible to determine directly both and plastic work in bending arm around mandrel. The suitability procedure examined various types metal arms, which are classified terms their ability deform plastically during test. also predicted theoretically, comparisons made between measured calculated values. energies determined...
ABSTRACT Standard peel tests for aerospace laminates based on metal–polymer systems, namely floating-roller and climbing-drum methods, have been accommodated in a unified theory of peeling. This also accommodates more basic such as T-peel fixed-arm newer methods mandrel peel. These five applied to two laminate systems critically examine their use the determination adhesive strength. The has used unify outputs from terms fracture toughness. In this way, comparative merits can be commented on....
A methodology is proposed for modelling transverse matrix cracks in laminated composites a three-dimensional explicit finite element analysis framework. The method based on the introduction of extra degrees freedom to represent displacement discontinuity and use cohesive zone model determine damage evolution crack propagation. designed laminates made uni-directional fibre-reinforced plies, allowing several assumptions be which greatly simplify algorithm. This was implemented commercial...
