Design of Lightweight Composite Disks Reinforced with Continuous Fibres

Abstract

The paper presents the results of an investigation in the area of numerical analysis and designing of lightweight composite disks reinforced with continuous fibres. The problem of the optimal layout of reinforcing fibres in the matrix domain in order to obtain the minimal weight of the disk with assumed mechanical properties is considered. The case of the creation of linear and curvilinear fibres is discussed. An adequate model of the composite structure is presented as well as the optimisation task for this type of design problem, and the method of solving this task is formulated in the paper. The design problem is illustrated by a simple numerical example.
