In this experimental study a hybrid composite shaft was fabricated by wrapping 200 GSM carbon and 450 GSM E-glass woven fabric fibre with 7121 PA matrix material, completely around aluminium tube with manufacturing method in which hand layup method aided with high pressure compressed air is productively used for the purpose that woven fabric could conform to curved surfaces. A pendulum type drop weight test setup was construct which is able to produce low-velocity transverse impact damage on composite specimens. A total of twelve specimens were manufactured in which three specimens from each type of composite material and three bare aluminum tubes are impacted at energy level of 10.5 J on two consecutive points whish are 50 mm apart along the longitudinal axis of specimen, eighteen specimens in total, were tested under torsion, three point and four point bending test. For a low velocity impact, it is notice that invisible cracks develops in carbon/glass fibre along with small conical impression occur in aluminum tube in hybrid aluminum composite tubes. Load-deflection & torque-angle of twist relation data were documented for with and without impact damage specimens and compare these data.
