This paper addresses the effect of temperature on mixed-mode interlaminar fracture toughness and fatigue delamination growth rate a carbon-fibre/epoxy material, namely IM7/8552. Quasi-static characterisation tests were carried out at −50 °C, 20 50 °C 80 using asymmetric cut-ply coupons. The experimental results show that may have an accelerating or delaying growth, depending loading regime, i.e. either quasi-static fatigue. Fractographic examinations also in order to assist interpretation...
This paper describes the development and characterisation of a novel type composite Z-pin able to accommodate large deformation without exhibiting fibre failure. Three types pseudo-ductile Z-pins are fabricated by means micro-pultrusion polybenzoxazole (PBO) fibres. Namely, unidirectional PBO (uPBO) in combination with ductile (uPBO/DCT) brittle (uPBO/BT) matrix system developed, together twisted (tPBO/DCT). Single pin bridging tests carried out across full mode mixity range from I (Φ= 0) II...
The prediction of delamination onset is a challenging task in the design thick tapered composite laminates, where multiple ply terminations ("drop-offs") are present. This paper addresses development global-local finite element-based approach for whereby layered Timoshenko beam models employed to predict initiation from individual drop-offs. modelling strategy provides fast and conservative method evaluating strength laminates. Parametric test cases presented order validate methodology...
Increased electrification of aircraft power systems has been widely presented as a route toward meeting environmental and emissions targets for performance, via more-electric future hybrid-electric concepts. In parallel, the superior mechanical performance carbon fiber reinforced polymer (CFRP) resulted in its increasing use structures. The relatively low electrical conductivity CFRP compared to traditional aluminum structures copper conductors limits structural elements, so separate are...
This research delves into the failure mechanisms exhibited by unidirectional Carbon Fiber Reinforced Polymer (CFRP) composites under longitudinal compression, while considering interplay of three types manufacturing-induced defects: initial waviness fibres, void volume fraction, and size. The study employs 3D high-fidelity intact representative element (RVE) models, incorporating fibres voids based on Micro-CT imaging. A novel algorithm is proposed to generate more accurate shapes, departing...
A comprehensive conceptual design study is performed to assess the potential benefits of span morphing technology and determine its feasibility when incorporated on medium altitude long endurance unmanned air vehicles. representative vehicle based BAE Systems Herti was selected. Stability control are investigated by operating asymmetrically replace conventional ailerons. The Tornado vortex lattice method for aerodynamic predictions. sensitivity rolling moment generated different flight...
