Abstract
The failure mechanism of PBTP was improved by the addition of highly dispersed iron/iron oxide to the polymer. The mechanical behaviour of the materials under impact was investigated, and the addition of highly dispersed iron particles was shown to stabilise the failure mechanism of PBTP and improve its mechanical properties. This was attributed to increased interphases between crystalline and amorphous phases, decreased crystalline size, increased network entanglement density and decreased critical structural defect length. 14 refs.
