机匣包容环布带缠绕成型工艺研究
Research on the winding process of the engine casing retaining ring
摘要
Abstract
In this paper,the hot-melt method was used to prepare aramid/epoxy prepreg 023F/DBE-125 and fiberglass/epoxy prepreg SW280F/DBE-125.Composite material test plates were made using the autoclave process,and their mechanical properties and ballistic impact resistance were characterized.To address the deformation issues encountered during the winding,curing,and processing of the thin-walled engine casing,the mold and the assem-bly gap of the casing,along with the material's thermal expansion differences,were used as the design basis for the winding mold of the engine casing retaining ring.Through simulation technology and process trials,suitable winding and processing parameters were determined.Using the parameters obtained from the trial pieces,composite retaining rings were wound onto thin-walled engine casings,and the formed retaining rings were subjected to dimensional and internal quality inspection.The test results show that the performance indicators of the developed engine casing retai-ning ring meet the required standards.This study provides an important reference for the lightweight design and manu-facturing of engine casings and has significant implications for the development of key components in aircraft engines.关键词
