Offshore Standard DNV-OS-C501, November 2013 App.H Example for representative data – Unidirectional carbon tapes made of TPW tape with “5631” fibres – Page 243 H.1 General H.1.1 APPENDIX H EXAMPLE FOR REPRESENTATIVE DATA – UNIDIRECTIONAL CARBON TAPES MADE OF TPW TAPE WITH “5631” FIBRES H.1.1.1 This appendix describes an example of a set of data for a carbon fibre reinforced epoxy laminate. The laminates were made of Carbon Tape TPW reinforced by four different types of fibres. H.1.1.2 Data were supplied by Tenax Fibers, Germany. H.1.1.3 Laminates made of similar carbon fibres may be similar to this example and can be qualified according to Sec.4 [8.6] - Qualification against representative data. H.1.1.4 Matrix dominated properties may change considerably when changing the resin system. H.1.1.5 Laminates made of carbon fibres with different characteristics may have very different properties from the ones listed here. H.1.1.6 Representative data for other materials can be measured and used like this example, as long as the requirements given in Sec.4 [8.5] and [8.6] are fulfilled. H.1.1.7 There is a lack of data for matrix dominated properties and of properties in air and water. Properties in other fluids are not listed, since only few and specific data exist. If such properties are needed some qualification testing may be required. H.2 Definition of material The material is described according to Sec.4 [8.5.2].
