Surfboard Foam 3-Point Bend Test
A company manufacturing surfboard blanks, made from rigid polyurethane (PU) foam, undertake a stringent testing program to guarantee the rigidity of the foam and strength of the final surfboard product. The blank must maintain a certain level of hardness throughout its construction to ensure its strength and responsiveness when ‘riding the waves‘. The company wanted a test solution to determine the peak load strength of PU foam samples by compressing them until failure occurred. A graphical representation of every test was also needed to provide an easy way of comparing results.
Mecmesin offered a suitable solution in the form of a motorised test system, together with an Advanced Force Gauge (AFG) and 3 point bend jig, all capable of testing up to 1000N. In addition, the customer was supplied with Windows based Emperor™ Lite software, which provides users with a ‘live‘ display of the test on a PC screen and enables evaluations to be made once the test is completed.
