Novel Sustainable Composites Incorporating a Biobased Thermoplastic Matrix and Recycled Aerospace Prepreg Waste: Development and Characterization KU Leuven
Carbon fiber-reinforced polymer (CFRP) composite materials are widely used in engineering applications, but their production generates a significant amount of waste. This paper aims to explore the potential of incorporating mechanically recycled aerospace prepreg waste in thermoplastic composite materials to reduce the environmental impact of composite material production and promote the use of recycled materials. The composite material ...
Forming-behavior characterization of cross-ply carbon fiber/PA6 laminates using the bias-extension test KU Leuven
This work focuses on the in-plane shear behavior of carbon fiber-reinforced polyamide 6 cross-ply laminates. Bias-extension tests are performed at different temperatures and deformation rates. Forming behavior is compared with the prediction of the pin-jointed net (PJN) idealization, and the effects of temperature and deformation rate are investigated. A key objective is to estimate the locking angle of the material. The results show that the ...
The Effect of the Setting Force on the Static Strength of a Blind Rivet Nut Set in CFRP KU Leuven
The continuous increase of structural composite applications urges the need for a profound understanding of the behaviour of mechanically fastened joints in lightweight composite materials. As opposed to adhesive bonding, mechanical fasteners come with easy installation and disassembly processes. However, mechanical fasteners are inherent stress raisers and therefore often deemed inappropriate for usage in composite structures. In this paper, ...
Smart material and design solutions for protective headgears in linear and oblique impacts: column/matrix composite liner to mitigate rotational accelerations KU Leuven
Oblique impact is the most common situation that cyclists experience during traffic accidents during which the human head undergoes both linear and rotational (angular) accelerations. Angular acceleration of the head is known to be linked to the majority of traumatic brain injuries. This paper proposes various solutions to mitigate angular accelerations of which an anisotropic column/matrix composite foam design is the most effective. This smart ...
Temperature dependence of thermophysical properties of carbon/polyamide410 composite KU Leuven
In this study, the temperature dependence of the carbon/polyamide 410 composite's heat capacity, thermal expansion, density, and thermal conductivity was investigated. The results demonstrated that the specific heat capacity of the C/PA410 composite increases with temperature, with major transitions observed at the glass transition (Tg) and melting (Tm) temperatures. Due to the presence of fibers, the CTE values in the fiber direction of C/PA410 ...
