- Abstract
Elastomer toughened PA6 hybrids reinforced with short glass fiber and organoclay were fabricated by melt mixing and injection molding. The structure, mechanical and hygrothermal aging behaviors of such hybrids were investigated. XRD patterns showed the absence of clay diffraction peaks in low angle region. TEM observation showed that the organoclay platelets are fully exfoliated in the PA6 matrix of hybrids. Mechanical tests demonstrated that the incorporation of organoclay into PA6/SEBS-g-MA/SGF composite lead to a significant enhancement in the elastic modulus of hybrids. However, the clay additions reduced the tensile ductility and fracture toughness of hybrids. The tensile stiffness and strength of the clay reinforced hybrids deteriorated but the tensile ductility enhanced markedly upon exposure to hygrothermal aging.
