Abstract :This work presents manufacturing of glass/polypropylene commingled yarns and analysis of low velocity impact insert ignore into journalissuearticles values(15J, 25J, and 35J); and compression after impact insert ignore into journalissuearticles values(CAI); performance of thermoset and thermoplastic composites produced from the  hybrid commingled yarns. Hybrid commingled yarns were produced through an air jet nozzle at different air pressures. Results showed that commingled yarn tenacity and mixture quality were highly affected by changing the air pressures. Impact tests indicated that thermoplastic composites absorbed around 73-80% of the impact energy while thermoset composites absorbed 39-41%. CAI tests presented that thermoplastic composite had higher residual strength with a different failure mechanism under compressive loading.
