Abstract: To obtain attractive properties, the structure of interpenetrating polymer networks (IPNs) is made from 2,7-bis (4-maleimidophenoxy) naphthalene (BMPN) and 2,7-dihydroxynaphthalene dicyanate (DNCY) containing 0.11 mmol/mol Fe(AcAc)₃ and 2% nonylphenol. The glass fibre reinforced composites are made from the novel IPNs bismaleimide-triazine (BT) resin containing BMPN and DNCY. Two T_gs and high storage modulus are shown in DMA curves of these composites. Two glass transitions could be detected between 250°C and 350°C, and the storage modulus show higher than 19,000 MPa. Opposed to composites of co-cure BT resin, the flexural property, dielectric property and moisture uptake value of composites are improved obviously due to the formation of IPNs structure for the composites. This composites show good flexural property, low dielectric constants (DC) and low moisture absorption.

Keywords: bismaleimide; cyanate; naphthalene; interpenetrating polymer networks; IPNs; glass fibre reinforced composites; GFRC; flexural properties; dielectric constants; moisture absorption.
