Abstract

"PROCESSO PARA COMBINAR CONTINUAMENTE FIBRAS DE ARAMIDA COM UM POLìMERO EXTRUSáVEL E PRODUTO" A presente invenção se refere a um processo para a obtenção de uma composição substancialmente uniforme de fibras de aramida curtas e polímero, no qual as fibras apresentam um teor de umidade significativo para melhorar as características de manuseio, e são parcialmente secadas e abertas pelas forças de cisalhamento em uma extrusora antes do contato com o polímero na extrusora.
