Mechanical Property of Surface Modified Natural Fiber Reinforced PLA Biocomposites

Mechanical Property Evaluation of Fiber-Reinforced and Fabric-Reinforced Zinc Oxide-Eugenol Temporary Filling Materials

Zinc oxide-eugenol (ZOE) is usually applied clinically as dental filling material for thermal insulation and temporary restoration. The objective of this study was to use ZOE as a composite matrix and low melting-point polyester fibers or fabrics as reinforcement. The added fibers or fabrics increased the composite materials’ compressive load by 250 N and 290 N, respectively. Fiber length and t...

Modeling the Anisotropic Mechanical Properties of Hydroxyapatite Whisker Reinforced Biocomposites

The ideal bone substitute biomaterial should have mechanical properties similar to that of human bone tissue. Hydroxyapatite (HA) alone suffers from low fracture toughness, and most polymers alone lack sufficient stiffness and strength, limiting applications in load-bearing implants. Synthetic HA whisker reinforced polymer biocomposites provide a means to overcome these deficiencies (Roeder, et...

Improving Interfacial Adhesion in Pla/wood Biocomposites

Effects of modified cellulose nanocrystals on the barrier and migration properties of PLA nano-biocomposites.

The aim of this paper is to report the impact of the addition of cellulose nanocrystals on the barrier properties and on the migration behaviour of poly(lactic acid), PLA, based nano-biocomposites prepared by the solvent casting method. Their microstructure, crystallinity, barrier and overall migration properties were investigated. Pristine (CNC) and surfactant-modified cellulose nanocrystals (...

Effect of Fiber Surface Treatment on Wear Characteristics of Carbon Fiber Reinforced Polyamide 6 Composites

Ozone modification method and air-oxidation were used for the surface treatment of polyacrylonitrile(PAN)-based carbon fiber. The surface characteristics of carbon fibers were characterized by X-ray photoelectron spectroscopy (XPS). The interfacial properties of carbon fiber reinforced polyamide 6 (CF/PA6) composites were investigated by means of the single fiber pull-out tests. As a result...
