Fatigue performance of composite laminates after impact

Reference number 2018-04776
Coordinator RISE SICOMP AB - Swerea SICOMP AB, Linköping
Funding from Vinnova SEK 275 350
Project duration December 2018 - June 2019
Status Ongoing

Purpose and goal

The main objective is to investigate the fatigue performance of impacted composite laminates. The behaviour of thin ply composites will be compared with conventional prepregs.

Expected results and effects

Benefits of thin-plies have already been shown in fatigue and impact testing on full thin-ply lay-up. Within this project, Oxeon will be able to gain more knowledge about their material being used in a hybrid lay-up (thin plies/thick plies) for fatigue after impact. With this gained knowledge, Oxeon will be able to increase future possibilities and strengthen existing collaboration with aeronautic companies. Aerospace industry is a key market for Oxeon as material supplier and is expected to make the sales increase and the business grow.

Planned approach and implementation

The project activities are divided as follows: 1: Manufacturing and Sample preparation, Activity leader: RISE SICOMP 2: Impact tests, Activity leader: RISE SICOMP 3: Tension-compression fatigue and quasi-static tests, Activity leader: LiU & SICOMP 4: Reporting, Activity leader: RISE SICOMP 5: Project closing workshop, Activity leader: RISE SICOMP Milestones (M) M1. Kick-off meeting M2. Specimens impacted and ready for fatigue tests M3. Report: Results from the testing and damage inspection M4. Project closing workshop and clear plan for future continuation
