Abstract:
This paper reports the responses of basalt unsaturated
polyester laminates under static three-point bending
loading and low-velocity impact. Three kinds of composite
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 locations.
From the different combinations of unidirectional
(0 ), cross-ply (0 /90 ) and woven lamina, the impact
behaviors could be optimized with the lowest area density.
