Studies on the mechanical properties of composites reinforced with nanoparticles

Abstract

In this article, the influence of nanoclay Closite 30B on the tensile, the flexural and the punch properties of 2D woven Glass/Epoxy laminate composite have been investigated experimentally. The glass/epoxy/nanoclay laminate have 12 layers and 50% fiber volume fraction is manufactured by VRTM method. Fibers have a plain‐weave configuration with density of 200 g/m2, while the nano‐epoxy resin system is made of diglycidyl ether of bisphenol A (Epon828) resin with jeffamine D400 as the curing agent and an organically modified modified montmorillonite in a platelet form, namely Closite 30B. The nanoclay is dispersed into the epoxy system in a 0, 1, 2, 3, 5, and 7% ratio in weight with respect to the nano‐matrix. The results have shown that the maximum improvement in the tensile strength, the failure strain, and toughness are 13, 7, and 27%, respectively, by 7% nanoclay and in the modulus is 9% by 3% nanoclay. The results of three bending flexural test indicate that the maximum improvement in the flexural strength and flexural modulus are 11 by 3% nanoclay and 48 by 5% nanoclay, respectively. Moreover, the result of punch tests have shown that the maximum improvement in energy absorbed is close to 46 by 5% nanoclay for crosshead speed of 1mm/min and close to 23 by 3% nanoclay for crosshead speed of 100 mm/min.

A Comparative Study on Structural, Morphological, and Tensile Properties of Binary and Ternary Epoxy Resin‐Based Polymer Nanocomposites

“…In aerospace military applications weight is a crucial point; thus, composite materials are considerably helpful since they have better specific stiffness (stiffness to weight) and specific strength (strength to weight) compared to conventional materials. Recent structural applications demand novel materials; therefore, nanomaterials and polymer composites have been widely investigated and developed [2]. ere is also an escalating need for materials having high exceptional mechanical properties since polymer and its composites are being greatly used [3].…”

Polylactide/organoclay nanocomposites: The effect of organoclay types on the structure development and the kinetic of cold crystallization

“…In recent years, polymer nanocomposites based on the organoclay signify a class of new structural materials which are quickly replacing the conventional polymers due to enhanced thermal, mechanical, barrier, and flame retardancy properties as compared to virgin polymers . Hence, it would be expected that the combination of PLA and organoclay forms a compostable polymeric hybrid with enhanced properties.…”

Synergistic effects of thermoplastic and nanoclay on the performance properties and morphology of epoxy resin

“…Researchers explained differently the increase in roughness of epoxy resin due to modifier incorporation. Pol and Liaghat attributed this fact to the distortion of the crack tip path which is altered from its straight way.…”
