Multiscale fiber reinforced composite with enhanced thermomechanical and mechanical properties can be attained with very low filler loaded-nanophased matrices.
In fabricating M-FRCs there are some limitations that can arise during VARIM processing (i.e.,nanoparticle filtering).
This is caused by the nanoparticles being trapped in inter-tow regions within the fiber preform mesh during fabrication.
Filtering is more apparent when using nanoparticles that have high aspect ratios (i.e., CNF and CNT) [4,7,10].
Due to some of the limitations that may hinder the production of quality M-FRCs with reproducible properties, other approaches to fabricate M-FRCs are being explored. Multiscale fiber reinforced composites that possess a suite of properties and low production costs make them prime candidates for potential future applications.
