The Thermal Properties of Glass Fiber Reinforced Epoxy Composites with and without Fillers

Abstract

Summary: An experimental study has been carried out in order to investigate the thermal properties of glass fiber reinforced epoxy (G-E) composite with inorganic nano and micro fillers namely silica, alumina and aluminatrihydrate. The hybrid composites were fabricated by ultrasonication and pultrusion techniques. Morphological characterization was carried out by Scanning electron microscope (SEM) and the micro-graphs revealed an improved dispersion quality of fillers in the G-E composite. The thermal conductivity, glass transition temperature, thermal stability and coefficient of thermal expansion were investigated as per ASTM standards. The results reveal that the best performance was found to be in Al 2 O 3 þ SiO 2 þ ATH þ G-E hybrid composite.

Experimental and theoretical studies on the adjustable thermal properties of epoxy composites with silver‐plated short fiberglass

“…This result was attributed to the lower CTE of fiberglass. However, previous literature reported that the CTE of epoxy‐based composite containing 20 vol % short glass fibers fell by 32% compared with that of neat epoxy (178.6 × 10 − 6 K − 1 ) . By contrast, it is found that the short glass fibers in our study have higher aspect ratio than the ultra‐short glass fibers.…”

“…Previous studies reported that short glass fibers were used to decrease the CTE of polymeric composites . Moreover, the fiberglass with high aspect ratio can form a percolation network at a lower filler concentration.…”

The effect of intumescent mat on post-fire performance of carbon fibre reinforced composites

“…The successful commercial flame retardants for polymer matrix with effective performance are halogenated flame retardants such as tetrabromobisphenol (TBBPA) 10 , the release of smoke, carbon monoxide and corrosive gases (namely HBr) during the burning results in environmental effect with health hazards [9][10][11] . Furthermore, the alternative flame retardants such as phosphorus and inorganic based, present a significant negative impact on mechanical behaviour which is mainly expressed regarding tensile behaviour, flexural properties and impact properties [12][13][14] .…”

Investigation of physical, mechanical, and thermal properties of glass fiber reinforced polymer composites strengthened with KH550 and KH570 silane-coated silicon dioxide nanoparticles

“…As heat dissipation and management in electronics and electrical devices made of polymer composites are problematic issues, electrically insulative and thermally conductive products can be produced by adding nanoparticles into the polymer matrix. 19,20 The extensively used nanoparticles for polymer matrix modifications are silicon dioxide (SiO 2 ), 21,22 aluminum oxide (Al 2 O 3 ), 12 titanium dioxide (TiO 2 ), 23 boron nitride (BN), 24 carbon nanotubes (CNT), graphene oxide (GO).…”
