Effects of extrusion ratio (ER) during extruding on mechanical properties of poly(lactic acid) (PLA) screws were investigated in terms of shear and twist strength. Shear strength increased by drawing, while twist strength decreased. This might be due to orientation of molecular chains during ...
Laminate sheet of poly(lactic acid)-based resin and thermoformed plastic contain nucleating agent, namely aliphatic carboxylic acid amide.8 A flat film for thermoforming with high toughness, high stiffness and high transparency is based on polyolefin composition comprising α-nucleating agent, such as,...
The muscle can produce the lactic acid to cause the muscle to be at the tight condition if weary.Drinks the alkalinity calcium ion water, after the calcium ion enters the blood to be possible to form the compound calcium lactate with the lactic acid union and to carry over in vitro, cause...

The influence of solid-state drawing on the morphology of melt-spun poly(l-lactic acid) (PLLA) tapes, and the accompanying changes in mechanical and degradation behaviour have been studied. Mechanical properties are found to be strongly dependent on both applied draw ratio and drawing temperature....
Uniaxial deformation of amorphous poly(lactic acid) (PLA) film was performed at 60掳C (around the glass transition temperature). The deformed samples revealed a strain-induced mesophase, and its fraction and thermal stability increased with draw strain. Further annealing was performed in situ at ...
