| Abstract: | This paper demonstrates results of an experimental study on
glass/epoxy laminated composites subjected to low velocity impact at energy
levels equal to 10, 15 and 30 J
under variable temperatures in the range of -30°C to 23°C. The
configuration of specimens is quasi-isotropic. The low temperature and its
influence on the maximum absorbed energy, elastic energy, crack length and
delamination are highlighted. Also, the effects of geometry index
(span-to-depth) and notch orientation are studied. Failure mechanisms of
specimens are examined using microscopic examinations. Results indicate that
impact performance of these composites is affected over the range of
temperature considered. Failure mechanism is changed from matrix cracking at
room temperature to delamination and fiber breakage at low temperatures. |
