| Research Abstract |
The objective of this study is to clarify the strength properties for the natural fiber reinforced composites (green composites, GC) from the single twist yarn composite (SYC) to unidirectional twist yarn GC laminates using ramie fibers. At first in-situ observation system during tensile tests under optical micro-scope was designed and conducted for SYC tests. Then SYC specimens with various twist per inch (TPI) were prepared and in-situ observation under tensile loading was carried out. Consequently it was confirmed that a breakage of one fiber involved other breakages, the splitting of yarn from matrix resin occurred and the stress recovery from yarn breakage was identified. Additionally the TPI dependence on the strength properties for unidirectional twist yarn GC laminates was clarified.
