Recent Advances in Green Composites

Abstract

This review aims at reporting on very recent developments in the, properties and applications of Green Composites. One very important aspect of green composites is that they can be designed and tailored to meet different requirements. Recent advances in natural fiber development offer significant oppurtunities for improved materials from renewable resources. Biocomposites offer a significant non-food market for crop-derived fibres and resins. Considerable growth has been seen in the use of biocomposites in the automotive and decking markets over the past decade or so, but application in other sectors has hitherto been limited. Recent developments of different biodegradable polymers and biocomposites are discussed in this review article.

Physical, Mechanical and Thermal Properties of Sugar Palm Yarn Fibre Loading on Reinforced Unsaturated Polyester Composite

“…However, the increase of fibre loading increases composite odour as well as water uptake. 1,33 Recently, several studies have been conducted to determine the natural fibre loading optimum value within the composites in order to improve their mechanical properties. Per Shalwan and Yousif, there is not yet a fibre volume faction and natural fibre loading universal value for which an optimum tensile strength could be achieved.…”

“…27 Furthermore, several researchers have commonly agreed that at a high volume fraction (above 50%), fibres tend to form aggregations which result in the weakening of the interfacial area and debonding between the fibres and matric. 29,[33][34][35][36] Therefore, the objective of this study includes investigating the effects of sugar palm fibre yarn loading on the physical, mechanical and thermal properties of reinforced unsaturated polyester composites. ); methyl ethyl ketone peroxide (MEKP) (Butanox-M50) as curing initiator; and cobalt as reaction accelerator were supplied by CCP Composites Resins Malaysia Sdn.…”

Treatise on Sustainable Infrastructure Construction: Green Composites, Cross Laminated/Mass Timber, Wood Truss Connectors, Nondestructive Technologies, Health Assessment and Monitoring: Utility Poles and Geofoam

“…The significant advances in the development of green and environmentally friendly materials have placed this type of composites at the forefront of research and development [1][2][3][4][5][6][7][8][9]. Although laminated composites have been used for over a century, the literature lacks adequate studies on the effects of bonding stiffness on the overall performance.…”

A new method of characterizing material viscoelastic property by using vector fitting

“…Loss modulus is proportional to the amount of energy dissipated as heat by the sample . The mechanical damping coefficient is the ratio of the loss modulus to the storage modulus and is related to the degree of molecular mobility in the polymeric material . The experiments include stress relaxation, , creep, , and dynamic mechanical analysis using multiple fixed frequencies .…”
