In the present work, dry fibre placement (DFP) of co-polyamide based carbon spreadtow bindered tape for fabrication thermoplastic acrylic resin composites was explored. The DFP followed by vacuum assisted liquid infusion (LRI) is expected to be an alternative process traditional preforming approaches. This research work looks at influence water immersion on performance studied. thermo-mechanica...

This paper proposes a lightweight detection model based on machine vision, YOLOv5-GC, to improve the efficiency and accuracy of detecting classifying surface defects in preforming materials. During this process, clear images entire are difficult obtain due stickiness, high reflectivity, black resin thermosetting plain woven prepreg. To address challenge, we built vision platform equipped with l...

Understanding the role that exciton diffusion plays in organic solar cells is a crucial to understanding recent rise power conversion effciencies brought about by non-fullerene acceptors (NFA). Established methods for measuring lengths require specialized equipment designed high-resolution time-resolved photoluminescence (TRPL). Here we introduce technique, coined pulsed-PLQY, measure length of...

Preforming processes can be used for automated manufacturing of fiber reinforced polymers. Different technologies are processing dry textile fabrics into 2D or 3D preforms. Due to missing tack fabrics, auxiliary binder systems fixation the onto a substrate material and in order achieve sufficient adhesion between layers. In this study, seven reactive non-reactive tackifying agents have been dis...
