Abstract:A number of methods are available for preparing a fiber reinforced polymer composite from two or more polymer matrixes and fibers. Many difficulties (for example, increasing viscosity of processing fluid, homogeneity of fibers in the matrix, and so on) during composite preparation process limit the fiber diameter and length. We propose new type reinforced polymer composites by in situ coffining electrospun fibers into polymer matrix. The reinforced composites have the structure that one-dimensional polyvinyl alcohol (PVA) fibers are coffined into the polystyrene (PSt) matrix. AFM image of the PVA-PSt composite film prepared by in situ coffining method shows its fibrous surface with many trenches. The electrospun PVA fibers carve the trenches on the film surface. Film elongation of the PSt cast film and the PVA-PSt reinforced composite film under heating condition was investigated. Both of the PSt-based films started to elongate over 80°C. However, the elongation of the PVA-PSt composite film was smaller than that of PSt cast film. This suggests that the electrospun PVA fibers coffined into the PSt matrix reinforce the composite film.
