F. Suhara et al., STUDIES ON THE CURING OF SHORT POLYESTER FIBER-POLYURETHANE ELASTOMERCOMPOSITE WITH DIFFERENT INTERFACIAL BONDING AGENTS, Plastics, rubber and composites processing and applications, 24(1), 1995, pp. 37-41
The cure characteristics of polyester short fiber-polyurethane elastom
er were studied with respect to different fiber-matrix bonding agents.
A hexamethylenetetramine-resorcinol-hydrated silica based bonding age
nt was found to affect the stability of the composite. A new bonding a
gent, TP resin, based on polymeric toluenediisocyanate and polypropyle
ne glycol has been developed. Cure characteristics of the composite wi
th and without TP resin at different fiber loadings were also compared
. Minimum torque, scorch time and optimum cure time increased with fib
er content. Maximum torque was consistently higher with TP resin at al
l fiber loadings.
