Interminar Shear

ASTM D2344

Test Specimens

* Speed of Testing: Edge shall be parallel and cuts made along radial planes of the ring.

< Horizontal Shear Test Specimen (Ring Specimen) >

< Shear Test Specimen(Flat Laminate) >

Table 1. Recommended Ratio of Span and Specimen Length to Thickness

Reinforcements Span Thickness Length/Thickness
Glass fibers 5 7
Graphite fibers 4 6
Carbon fiber 4 6
Steel Wire 4 6
Boron filaments 4 6
High modulus organic strands (aramid, etc.) 4 6

- Span length equals specimen length for ring specimen
- Total length for flat specimens

* Speed of Testing : 1.3 mm(0.05 in)/min

Calculation

* Shear strength
