Abstract
PNEU PARA VEÍCULO AGRÍCOLA COMPREENDENDO UM ELEMENTO DE REFORÇO DE CARCAÇA HÍBRIDA. A invenção se refere a um pneu para veículo agrícola (10) que compreende pelo menos uma manta de carcaça (28) que compreende um ou uma pluralidade de elementos de reforço de carcaça (36) híbrida. O pneu (10) é obtido por um processo que compreende uma etapa de fabricação de cada manta de carcaça (28) na qual submerge-se os elementos de reforço de carcaça (36) ligados em uma composição polimérica para formar cada manta de carcaça crua (27), a relação entre o módulo tangente à força equivalente desenvolvida pela manta crua a 7% de prolongamento e o módulo secante à força equivalente desenvolvida pela manta crua a 1% de prolongamento é superior ou igual a 2,00. A densidade de elementos de reforço de carcaça (36) na manta de carcaça crua (27) vai de 50 a 150 elementos de reforço de carcaça (36) por decímetro de manta de carcaça crua (27) e cada elemento de reforço de carcaça (36) faz um ângulo superior ou igual a 85° com a direção circunferencial Z do pneu (10).
