Abstract
Anisotropic composite plates were evaluated with nanofiber reinforced matrices
(NFRM). The nanofiber reinforcement volumes ratio in the matrix was 0.01. The
plate dimensions were 20 by 10 by 1.0 in. (508 by 254 by 25.4 mm). Seven
different loading condition cases were evaluated: three for uniaxial loading, three
for pairs of combined loading, and one with three combined loadings. The
anisotropy arose from the unidirectional plates having been at 30° from the
structural axis. The anisotropy had a full 6 by 6 rigidities matrix which were
satisfied and solved by a Galerkin buckling algorithm. The buckling results
showed that the NFRM plates buckled at about twice those with
conventional matrix.
Keywords: combined vibration frequencies, buckling influence, plate vibration at
different or orientation angles, comparisons with conventional matrix.
1 Introduction
Considerable research activities in nanocomposites have been actively pursued
recently. One aspect of this research is on nanofiber reinforced matrices (NFRM)
which can subsequently be used as matrices in conventional reinforced fiber
composites [1–3]. Reference [1] includes pertinent references to that date.
Reference [3] includes additional references to 2009. However, to date, the
vibration of composite plates with NFRM has not been investigated yet. This is
the objective of the present paper, to use commercial composites with NFRM
loaded at 30° from the material axis (Fig. 1) for seven different load cases shown
in Table 6 for uniaxial and combined load conditions.
Keywords
combined vibration frequencies, buckling influence, plate vibration at
different or orientation angles, comparisons with conventional matrix.
