Failure modes of CF-PEEK overmoulded onto unidirectionally reinforced CF-LM-PAEK: Multi-scale pull-off testing and microscopy investigation of rib stiffened geometries
Overmoulding is a manufacturing technique used to create structural composite components with complex shapes, combining regions of continuous and short fibre reinforcement. It is possible to produce structural parts at high rates, whilst minimising materials costs. The interface between the regions of continuous and short fibre material is key to the performance of the structure. This work investigates pull-off testing as a direct method for measuring rib-on-plate bonding strength, a common structural feature of overmoulding. Different rib joint types (Butt, Radius, Step) and specimen sizes (1, 5, 20 mm) are used to investigate the fidelity of the test, when applied to unidirectionally-reinforced low melting point (LM)-PAEK bonded to PEEK ribs.The main findings are that the Butt joint appears to provide the most reliable pull-off test data in terms of determining the interface strength. While the Radius and Step configurations improve local strain and moulding consistency respectively, they tend to promote failure through the ply structure rather than the interface. Recommendations are made in relation to specimen length, ply structure and allowable deformation during manufacture.
期刊介绍:
Composites Part B: Engineering is a journal that publishes impactful research of high quality on composite materials. This research is supported by fundamental mechanics and materials science and engineering approaches. The targeted research can cover a wide range of length scales, ranging from nano to micro and meso, and even to the full product and structure level. The journal specifically focuses on engineering applications that involve high performance composites. These applications can range from low volume and high cost to high volume and low cost composite development.
The main goal of the journal is to provide a platform for the prompt publication of original and high quality research. The emphasis is on design, development, modeling, validation, and manufacturing of engineering details and concepts. The journal welcomes both basic research papers and proposals for review articles. Authors are encouraged to address challenges across various application areas. These areas include, but are not limited to, aerospace, automotive, and other surface transportation. The journal also covers energy-related applications, with a focus on renewable energy. Other application areas include infrastructure, off-shore and maritime projects, health care technology, and recreational products.
