Abstract

The purpose of this study was to examine the dynamic response of acrylonitrile-butadlene-styrene (ABS) when exposed to UV light. Impact-Resistant Easy-to-Form ABS sheets were tested using a Shock Tube. Three samples were tested at no UV light exposure and three were tested after 15 days of being exposed to rapid UV degradation rays. All samples were tested at a shock wave equivalent to 400 psi. The results showed that the UV damaged samples experienced a decrease in strength and energy absorption in comparison to the non-UV damaged samples. The average peak load for the non-UV degraded was 1261.89 Newtons and for the UV degraded it was 1069.87 Newtons. The specific energy absorption for the non-UV samples was 0.148 kJ/kg and for the UV degraded samples it was 0.130 kJ/kg. There was some embrittlement present in the UV damaged samples which led to it not wanting to deflect as much as the non-UV samples. This also meant that it took less energy to deflect the UV samples in comparison to the non-UV degraded ABS samples.
