Interfacial mechanical properties of carbon/glass hybrid thermoplastic epoxy composite rods play a crucial role in the determination strength and fracture behavior. In this study, push-out push-back tests using three with different ratios were performed to investigate interfacial shear mechanism. Debonding occurred at interface between glass fiber bundles epoxy. After onset debonding, sinusoida...

Abstract This paper proposes a netlike energy director (ED) made of carbon fiber-reinforced thermoplastic (CFRP) composites for ultrasonic welding. To explore the benefits using EDs, joint qualities with flat EDs and without are included references. The influence ED geometry on weld attributes quality investigated in terms cross-sectional microstructure, fracture morphology, maximum shear load....

High adhesion strength in hybrid composites is a decisive factor for their widespread use lightweight structures. The bond of co-bonded thermoplastic-thermoset largely influenced by the interphase thickness and morphology, which are controlled cure diffusion kinetics. Hence, this study aims to characterize composite comprised thermoplastic elastomer (TPE) glass fiber reinforced epoxy (epoxy/gla...

Abstract This work investigates the potential of improving mechanical performance braided composite beams through introduction local braid angle variations. Tubular with a 45°/60°/45° length-wise (axial) variation were manufactured and tested in quasi-static three-point flexure their was compared having layer-wise (radial) [±60°/±45°/±45°] variation. Compared to uniform angles, axial tailoring ...

Natural fibres have been identified as a potential substitute for mineral fillers in thermoplastic matrix composites automotive applications. However, natural are known to be susceptible thermal degradation at relatively low temperatures. This paper focuses on the characterisation of and mechanical date palm coir part an evaluation their reinforcement polypropylene composites. The resultant vol...

Generally, to produce film-type thermoplastic composites with good mechanical properties, high-performance reinforcement films are used. In this case, films used as a matrix are difficult to impregnate into tow due to their high melt viscosity and high molecular weight. To solve the problem, in this paper, three polypropylene (PP) films with different melt viscosities were used separately to pr...
