Effect of green hybrid fillers loading on mechanical and thermal properties of vinyl ester composites

Abstract

The need of eco-friendly materials has been attracted due to renewability, abundance availability, low cost, and so on. Therefore, the search for bio llers for the production of bio-based composite materials is gaining more and more attention in both academic and industry circles because it promotes sustainability. The present study represents the utilization of biomass solid waste in the hybrid form of tamarind seed and date seed powder into polymer reinforced composite which has been explored for the rst time by a compression molding technique. These llers are bio-waste that can be obtained at a minimal cost from renewable sources. An attempt has been made to use these hybrid llers to reinforce with the matrix ranging from 0 to 50 wt.%, and their physical, mechanical, and thermal properties were investigated. In general, the inclusion of hybrid llers increases mechanical properties, although the addition of hybrid llers had only a minor impact on thermal properties. When compared to the pure vinyl ester resin, the hybrid llers reinforced composites revealed a signi cant improvement in tensile, exural, impact, and hardness properties, with improvements of 1.51 times, 1.44 times, 1.87 times, and 1.46 times respectively, at 10 wt.% ller loading. Filler matrix interaction of fractured mechanical testing samples was analyzed by scanning electron microscope. Based on the ndings, hybrid ller reinforced composites may be suitable for applications where cost is a consideration and where minor compromises in thermal qualities are acceptable.

New Reinforcing Approach for Biobased UV-Curing Resins: Hybrid Lignocellulose Fillers with Improved Synergy and Wood Structure Mimics

“…This corresponds to the reported strong filler’s tendency to agglomerate above loadings of 2 wt % . The threshold content for agglomeration is reduced when multiple fillers are introduced . Therefore, a hybrid filler combination can be deployed more homogeneously in the resin.…”

Investigation of Mechanical and Thermal Stabilities of Tamarind Seed- and Peanut Shell Powder-Reinforced Vinyl Ester Composite

“…To prepare vinyl ester specimens with variable fller loadings ranging from 5% to 30%, a specifc mold is designed (200 × 200 × 3 mm). Carbon black-made mold release wax was initially applied on the surface of the mold and on the cover plate to make it easier to remove the plates, which are cured as soon as they achieve their fnal state [15]. Ten, the promoter (10% N,Ndimethylaniline) of about 1.5 wt% was added to a known volume of VE resin.…”

“…Mechanical tests (tensile, fexural, and impact) and Barcol hardness tests reveal that the best strength of the composites is achieved at a fller content of 10 wt.%. Tey claimed that hybrid fller composites are suited for use in the production of end products because the composite material has a low impact on the environment and can be applied to a variety of industrial applications as well as home applications [15]. Aradhyula et al reinforced polypropylene (PP) biomaterials with biowaste catla fsh scale (CFS) and proved that adding CFS content increased the fexural strength by 5%, density by 1%, and hardness by 11% of the PP/CFS composite.…”

Recycle of bio‐waste banana and sisal fiber filled harmlessness epoxy hybrid composite for automotive roof application

“…However, the characteristics of natural fiber‐reinforced composites depend on the interfacial bonding strength between the matrix and reinforcement fibers. It relates to the number of fibers and matrix, fiber length, pre and post‐surface treatment process, and incorporation method (Arzondo et al., 2004; Aseer et al., 2014; Nagaprasad et al., 2022). The combinations of sisal and glass fiber in polypropylene composite found increased thermal adsorption characteristics and the decomposition was controlled by high temperature (Isaac Premkumar et al., 2020; Oushabi, 2019).…”
