Evaluation of Bearing Strength of Next Generation Thin-ply Composite Material

Purpose and goal

The objective was to evaluate the bearing strength of Textreme Spread Tow fabric, a thin-layer composite material from OXEON. The results indicate the bearing strength of the Textreme material is on the same order of magnitude as an alternative thin layer material from OXEON and a conventional SAAB composite material. A decrease in areal weight below 100gsm for the Textreme material is expected to increase the bearing strength compared to conventional composite materials. Textreme material can be used to reinforce sensitive structural areas for aerospace applications.

Expected results and effects

The bearing strength of the Textreme material is on the same order of magnitude as an alternative thin-layer material from OXEON and a conventional SAAB composite material. The Textreme material can be used to reinforce sensitive structural areas for aircraft applications. A reduction of the areal weight below 100 gsm is expected to increase in bearing strength of the Textreme material. As a result of the project, the Textreme material will be used by SAAB in a NFFP7 project for further evaluation and improvement of bearing strength of fastener profiles in composite laminate.

Planned approach and implementation

OXEON manufactured and distributed the Textreme thin-layer composite material to SICOMP. SICOMP manufactured and prepared test specimens for testing according to SAAB specifications. Thereafter, the testing and evaluation of the test specimens were performed at SICOMP. The obtained results were presented to the project partners and discussed at a seminar. The planning of the project was good, with good communication among the project partners. As a result the implementation of the project was conducted in a smooth and rapid pace.
