Joints of Articles made of Polymer Composite Materials
Abstract
This report results from a contract tasking National Aerospace University as follows: High effectiveness of joints with transversal micro-fasteners, embedded in composite article, is proved experimentally in previous papers by the project manager. Project scope is working out structural and manufacturing solutions for metal-composite joints and correspondent of mathematical and experimental methods of engineering analysis. Following objectives are suggested to be considered in this project: (1) working out mathematical models and unified technique for determination stressed-strained state of joints with discrete, continuous and combined joining layer at arbitrary geometrical and rigidity parameters through the length of joining articles made of composites; (2) analysis of compliance coefficients influence on maximum stresses in articles and conformation of analysis formulas for determination compliance coefficients of micro-fasteners (0.8<d<2 mm), embedded in composite at the stage of its manufacturing; (3) working out the model of micro-fasteners interaction with composite reinforcement and obtaining formulas for determination composite elastic and strength properties in zones of curved reinforcement; (4) estimation of influence composite properties changing in zone of micro-fasteners embedding on stress distribution through joint length; (5) to prove that governing system of linear algebraic equations for stress determination in discrete joints has the same structure that Kirhgoff?s law equations for electrical chains analysis. New simulation technique of joints modeling based on this suggestion will be suggested.
