Polymer composite has contributed tremendously for energy efficient technologies in automotive and aero industries. Environmental and health concerns related to the carcinogenic nature of artificial fiber in polymer composite needs a retrofit. Eco friendly natural cellulosic fiber extract from the stem of Cissus quadrangularis plant is extensively characterized to consider as a viable alternative for man-made hazardous fibers. Anatomical study, chemical analysis, physical analysis, FTIR, XRD, SEM analysis and thermo gravimetric analysis were done to establish the certainty of using them as reinforcement fiber. Its light weight and the presence of high cellulose content (82.73%) with very little wax (0.18%) provide high specific strength and good bonding properties in composite manufacturing. The flaky honeycomb outer surface revealed through electron microscopy contributes for high modulus in CQ stem fiber and thermo gravimetric analysis ensures thermal stability up to 270 °C, which is within the polymerization process temperature.
