Abstract

Parul Singh and YG Bala

Flax fiber (Linum usitatissimum L) is the natural fiber which is good in mechanical properties such as impact resistance with specific strength. Now days, natural fibers are used in various field such as aircraft industries, automobile industries and textile industries. Due to low specific weight having comparable good mechanical properties these fibers is used in these industries. Flax fiber behavior changes with the hydro and thermal conditions due to hydrophilic nature. This paper is review about change in mechanical properties due to temperature and water absorption. Dynamic Mechanical Analysis (DMA) was performed to study the evolution of the glass transition temperature in function of the water uptake for composite samples immersed in distilled water at 30°C. Flax fiber have better fatigue resistance than other natural fiber. Flax fiber stiffness evolution is found that elastic modulus may increase or decrease over fatigue life in the fiber-direction.
