Effects of Injection Molding Conditions on the Mechanical and Visco elastic Properties of Glass Fiber Reinforced Thermoplastics (I) -Glass Fiber Reinforced Nylon 6 Composite-

유리섬유강화 열가소성 수지의 제조조건이 기계적 및 점탄성적 성질에 미치는 영향(I) -유리섬유 보강 나일론 6 복합재료-

The effects of glass fiber content and injection pressure on the mechanical and dynamic mechanical properties of glass fiber reinforced nylon 6 plastics were studied. On increasing glass fiber content, the fiber orientation, initial modulus, storage modulus and glass transition temperature increased, but the total energy dissipation in the glass transition region decreased. It was also found that the fiber orientation and the modulus had a maximum value at some critical injection pressure as the injection pressure increased. The reversed tendency was found in total energy dissipation.
