Abstract

Summary. The increasing use of composite structures in aircraft constructions has made it necessary to develop repair methods that will restore the component’s original design strength without compromising its structural integrity. In this paper, the complex repair technology of the composite wing of a light plane, which was damaged during an aircraft crash, is described. The applied repair scheme should meet all the original design requirements for the plane structure.

Highlights

In Poland in recent years, following the experience of other countries in the EU, it has been observed that sporting activities based on the use of ultralight (UL) planes have been developing rapidly.A
In accordance with the available data, there are currently more than 2,000 UL-class planes registered in Poland, of which the vast majority are mostly made from composite materials [1]
Apart from ever more complex plane constructions, this situation makes it necessary to develop repair technologies in order to restore the initial structure of the construction, as well as its design strength. This issue is becoming more significant, with regard to the difference between the technological level represented by the manufacturers of the planes of this type and that represented by the original equipment manufacturers (OEMs), as well as the methods applied in the course of repairing and operating them, especially as far as composite structures are concerned [2]

INTRODUCTION

In Poland in recent years, following the experience of other countries in the EU, it has been observed that sporting activities based on the use of ultralight (UL) planes have been developing rapidly. Apart from ever more complex plane constructions, this situation makes it necessary to develop repair technologies in order to restore the initial structure of the construction, as well as its design strength. This issue is becoming more significant, with regard to the difference between the technological level represented by the manufacturers of the planes of this type and that represented by the original equipment manufacturers (OEMs), as well as the methods applied in the course of repairing and operating them, especially as far as composite structures are concerned [2]. As a result, taking into consideration the still unsatisfactory level of the standardization of these methods, there is a need to collect the experience connected with them and generalize the data in question as far as possible
