Caracterización experimental del efecto de la tasa de deformación en el comportamiento mecánico de un compuesto termoplástico by Ramírez Montes, Carolina

“…In respond to the necessity mentioned above and taking into account that thermoplastics fiber-reinfroced (TFR) composites present several benefits over thermoset materials [1] and have been less studied, the present work focuses on experimental characterization of the strain rate effect on the mechanical behavior of woven polyphenylene sulfide (PPS) TFR composites (carbon and glass fiber) under compression loading using a Split Hopkinson Pressure Bar apparatus and an electro-mechanic universal testing machine for dynamic and quasi-static tests, respectively. …”
