Figure 7. Mechanical properties of the BPF homopolymerized, latent cured resin vs. commercially available high performance thermosets.
Tensile testing of cured specimens of our in-house BPF resin system were compared to both a conventional amine cured BPF (Epicote 862, cured with DETDA - as per the manufacturers guidelines) and Novoset 280 Cyanate ester resin (cured with Cu (ACAC)2 per the manufacturers guidelines). Note that our resin system has an increased Young’s modulus, comparable ultimate tensile strength and decreased elongation at break compared to that of the commercial BPF – it is in effect, stiffer and stronger. And while it is less stiff than the cyanate ester resin, it is significantly less brittle.
