The influences of the addition level of calcium sulfate whisker and modified calcium sulfate whisker on the T-peel strength of SBS adhesive were investigated. The difference of surface structure between calcium sulfate whisker and modified calcium sulfate whisker was studied by SEM. The results showed that the T-peel strength of SBS adhesive with 6phr calcium sulfate whisker was 694.8N/m, which was 17.
