Abstract
A review on optimization of adhesively bonded spar-wingskin joint (SWJ) of laminated fiber reinforced polymer (FRP) composites subjected to pull-off load is presented in this article using three-dimensional finite element analysis. Von Mises stress components have been computed across
the width of joint at different interfaces viz. load coupler-spar, and load coupler-wingskin interfaces. Further, the weight of SWJ structure is considered as the objective function which needs to be minimized for optimization. In the first step, the material and lamination scheme of the FRP
composite materials used for SWJ are optimized, and, in the second step, the geometrical parameters have been optimized on the basis of minimum von Mises stress and weight. Further, the effects of the material, lamination scheme, and geometrical parameters on the von Mises stress and weight
have been validated using the Analysis of Variance (ANOVA) approach as prescribed by the Taguchi method. The results show that the material and spar thickness are the most significant factors influencing von Mises stress. The weight analysis reveals that there is a significant effect of change
in material and wingskin thickness on SWJ performance. Suitable design recommendations have been made for SWJ in terms of material, lamination scheme and geometrical parameters.
期刊介绍:
With the explosion of research activity and reports, the need for concise and critical reviews of topics of contemporary research interest is manifest. Reviews of Adhesion and Adhesives (RAA) provides in-depth, incisive, illuminating and thought-provoking reviews written by subject matter experts covering all aspects of adhesion science and adhesive technology. Each review will be imbued with the author’s experience so that the reader will be able to assimilate the research in the area discussed easily and will be able to apply it in practice.The journal has relevance to a myriad of industries including textiles, printing, coatings, aerospace, medical, nanotechnology, biotechnology, building and construction, and microelectronics. The topics to be covered include, but not limited to, basic and theoretical aspects of adhesion; modeling of adhesion phenomena; mecha¬nisms of adhesion; surface and interfacial analysis and characterization; unraveling of events at interfaces; characterization of interphases; adhesion of thin films and coatings; adhesion aspects in reinforced composites; formation, characterization and durability of adhesive joints; surface preparation methods; polymer surface modification; biological adhesion; particle adhesion; adhesion of metallized plastics; adhesion of diamond-like films; adhesion pro¬moters; contact angle, wettability· and adhesion; superhydrophobicity and superhydrophilicity. With regard to adhesives, RAA will include, but not limited to, green adhesives; novel and high-performance adhesives; and medical adhesive applications.
