Abstract:
This paper reports the responses of basalt unsaturated
polyester laminates under static three-point bending
loading and low-velocity impact. Three kinds of com-
posite materials, unidirectional (0
), cross-ply (0
/90
)
and woven laminates were considered. The laminates
were fabricated by layup process and hot pressed
under pressure. Static three-point bending tests and
low-velocity impact tests were conducted to obtain the
force–deflection, force–time, deflection–time, velocity–
time, and energy–time curves. The results showed that
unidirectional (0
) laminates carried more load during
static loading, but in the event of dynamic loading,
cross-ply, and woven laminates were more superior. It
was observed that the failure of 0
laminates was
along the fiber direction while for cross-ply and woven,
the damage was localized, around the impacted loca-
tions. From the different combinations of unidirectional
(0
), cross-ply (0
/90
) and woven lamina, the impact
behaviors could be optimized with the lowest area den-
sity.
