Abstract

"SISTEMA LIGANTE PARA MANTA DE FILAMENTO CONTìNUO". Uma pasta ligante para uma manta de filamento contínuo usada em um sistema de pultrusão fenólica, compreendendo um silano fenólico compatível, um surfactante não-iónico, um antiespumante, água, um ácido orgânico e uma resina bisfenólica de epóxi em pó, tendo uma resina de dicianodiamida com ligação cruzada, termicamente ativa. A resina de pasta ligante é inédita, em que a resina bisfenólica de epóxi em pó, tendo uma resina de dicianodiamida com ligação cruzada, é compatível com resinas fenólicas atualmente disponíveis e, como tal, as peças pultrudadas produzidas possuem elevadas propriedades superficiais e mecânicas, em comparação com as tradicionais pastas ligantes do tipo poliéster, que não são compatíveis com resinas fenólicas. Mantas de filamento contínuo produzidas com a nova pasta ligante também podem ser convertidas em prepreg de epóxi, que pode ser usado para preparar peças compostas.
