Assessment of the technical and economic efficiency of implementing technology for field repair of machine body parts using dispersed-filled composites
Abstract
During operation, machine body parts are subject to wear and defects. Traditional restoration methods are often difficult to perform or not always available in the field, and replacing parts with a new one is economically costly. In this regard, the search and evaluation of the effectiveness of alternative repair technologies, such as the use of polymer composite materials (PCM), is relevant. The article calculates the technical and economic efficiency of using PCM in the repair of machine body parts. The efficiency calculation was carried out using the example of repairing a 20 mm long crack in the fuel tank of a KamAZ-5320 car. Several restoration methods were compared: traditional welding (welding), Seal-Lock technology, repair using PCM (epoxy-sand composites) in a repair facility and in the field, as well as complete replacement of the damaged part with a new one. Using PCM to repair body parts is a more cost-effective solution than welding or buying a new part. In addition to cost reduction, the key advantage of this method is its mobility and technological accessibility (the possibility of field repairs).
