Effective Thermal Conductivity of Plain Weave Fabric and its Composite Material Made from High Strength Fibers
Effective thermal conductivity High strength fiber Composite
2009/4/13
Structural models of yarn, plain weave fabrics, and plain weave fabric/resin composites were derived and theoretical formulas for the effective thermal conductivity were developed from these models. ...
手術用縫合糸に絹が多く使われていることは言うまでもない。これは、体に優しく刺激が少ない、
縫う際の操作性・耐久性に優れているなどの理由によるものと思われる。
近年、縫合糸の原料確保は中国に移行し、それとともに強度の低下が問題となっている。そこで
今回、農業生物資源研究所が保有している蚕品種の中から、高強度品種を選抜して縫合糸を試作し、
その物性について検討を行ったので、その概...
