Abstract
- Abstract: The effects of halogen-free flame retardants (FR) such as intumescent ammonium polyphosphate (APP) and melamine cyanurate (MC) on the flammability and mechanical properties of epoxy/glass fiber composite systems were studied. Overall, intumescent APP shows better flammability results compared with MC. The composite with 5vol.% APP performed sufficiently well in the UL-94 test and LOI, whereas 20vol.% MC is required to achieve similar results. The addition of 1vol.% MC into 4vol.% APP had shown some improvement on the composite flame resistance. The composite attains the maximum flexural strength at 15vol.% while the dynamic mechanical analysis shows that the addition of flame retardants increased the storage modulus but did not change the glass transition temperature Tg .
