The composite nanofibers were used as reinforcement in acrylic polymer for the overall enhancement of thermomechanical
properties, adhesion between fibers and matrix, and fracture toughness of the final nanocomposite
since acrylic materials lack of this feature. So, a good balance between hardness/toughness and transparency is
obtained with the addition of poly (vinyl butyral) (PVB) and titania (TiO2) nanofibers simultaneously and
controlling their contents. Specifically, when compared to that of pure acrylic polymer, the fracture toughness of
the PMMA nanocomposite apparently increased 55 % with the addition of 3 wt.% titania nanoparticles, while
the produced nanocomposite maintained high transmittance above 75–80% in the visible domain. The transmission
spectrum modelling of the reinforced fiber materials and hybrid acrylic composites using Mie scattering
theory for different particle sizes and particle content is presented. The calculated transmission coefficients
versus wa...velength are compared with the experimental ones.
