Development of an optimized large scale engine CFRP annulus filler


This proposal describes the effort planned by the partners FACC AG, Austria & University of applied sciences (UAS) Rapperswil, Switzerland, for the development of a CFRP annulus filler.
Production process will be an advanced preform concept with folding techniques and integration of all connection parts, injected with resin by an improved RTM process.
Part development will start with material tests on coupons, continued by the manufacturing of a prototype design, and finally ending in a close-to-series-production of 56 annulus filler.
In addition, a quality assurance supervisor accompanies the project from the beginning on in order to establish a quality measurement system suitable for a serial production.
Material- & process development will be led by UAS Rapperswil, while manufacturing, quality assurance and non-destructive testing will be under the responsibility of FACC.
FACC AG is Austria’s first-tier aircraft supplier in composite components, UAS Rapperswil is specialized in RTM process improvements and preform technologies.
