Fracture mechanics test methods for FRP composites

A summary of quasi-static delamination test methods for continuous-fibre, unidirectional FRP composites is given in Table 8.1. For mode 1, several standard test methods exist, namely, JIS K7086 ( Testing methods for interlaminar fracture toughness of carbon fibre reinforced plastics , 1993) this also includes a quasi-static mode 11 standard test, ASTM 

Mode Standard test method Standard test in preparation Remarks 

I JIS K 7086 ASTM D 5528 ISO 15024 Applicability to non-unidirectional FRP composites not fully assessed intralaminar (see Ref. [23]) for traw-laminar, see Ref. [24] 

III Not available ASTM round robins 1999 ff. (no current ASTM work item) [25,26] 

I/II ASTM D 6671 ESIS round robins 1994 ff. (no current activity) ESIS investigated a fixed ratio (4 3) mixed mode I/II test
