Abstract
Glass/Biofibers/Epoxy methacrylate of bisphenol-C (G/BF/EBCMAS) sandwich composites was
prepared by compression molding. G/BF/EBCMAS showed good mechanical and good to
excellent electrical properties and excellent chemical resistance. Studied properties are compared
with EBCMAS and G/EBCMAS. In comparison with G/EBCMAS, G/BF/EBCMAS showed
considerable decline of tensile strength (18-63.4%), flexural strength (18.8-38.7%), flexural
modulus (12.8-50.7%), Izod impact strength (17.4-43.5%), Barcol hardness (2.1-16.7%) and
dielectric strength (23.8-76.8%) except flexural strength of G/BM/EBCMAS. G/WC/EBCMAS
(96.7%), G/B/EBCMAS (79.2%), G/GN/EBCMAS (83.3%) and G/RH/EBCMAS (97.9%)
showed decline of volume resistivity, whereas other sandwich composites showed 1150-58233%
improvement. The decrease in mechanical properties and dielectric strength of G/BF/EBCMAS
sandwich composites is mainly due to poor interfacial adhesion and randomly oriented fibers.
Water absorption trend in different environments is H
2SO
4 (10.9-12.7%) > HCl (10.5-12.3%) >
NaOH (9.5-11.7%) > H
2O (8.3-11.0%) > NaCl (7.9-10.1%). Saturation time for G/BF/ EBCMAS
in different environments is 336-384 h (H
2O), 228-360 h (NaCl), 336-360 h (NaOH and HCl) and
312-360h (H
2SO
4), which is comparable with G/EBCMAS (336-384) except G/BC/EBCMAS
(288 h, NaCl), G/B/EBCMAS (312 h, H
2
O) and G/GN/ EBCMAS (228 h, NaCl). Sandwich
composites may be useful for low-cost housing and other specific applications.
