The main objective of this work is to compare the different fracture behavior of carbon fiber-reinforced composite T300/epoxy with cross-play composite laminate. Tension-tension and three points bending fatigue are adopted, with optical microscopic and scanning electron microscopic observation of the specimen fracture surfaces. The specific objectives are: a) for tension-tension fatigue loading, the onset and multiplication of transverse matrix cracks continuously improve the delamination. Consequently, fibers rupture occurs in this locally region with high density of cracks. b) The density of intralaminar cracks increases with number of fatigue cycles. c) During the shear stress distribution under three points bending fatigue, delamination which is the main characteristic of T300/epoxy, initiates from the central and propagates alone the neutral axis of the sample. And a small quantity of fiber breakage occurs in the maximal compress region.

Carbon Fiber Reinforced

Preserving the integrity of carbon fibers when recycling carbon-fiber-reinforced plastics (CFRPs) has been unfeasible due to the harsh reaction conditions required to remove epoxy resin matrixes, which adversely affect the properties of carbon fibers. We establish a practicable and environmentally friendly reclamation strategy for carbon fibers. Carbon fibers are recycled from waste CFRPs by an electrochemical catalytic reaction with the assistance of phosphotungstic acid (PA), which promotes the depolymerization of diglycidyl ether of bisphenol A/ethylenediamine (DGEBA/EDA) epoxy resin. The removal rate, mechanical strength, and microstructure of the recycled carbon fibers are analyzed to explore the mechanism of the electrochemical treatment. The influence of three factors—current density, PA concentration, and reaction time—are studied via an orthogonal method. Range analysis and variance analysis are conducted to investigate the significance of the factors. The optimal conditions are determined accordingly. The underlying CFRP degradation mechanism is also investigated.
