Experimental Evaluation of Carbon Fiber Reinforced Epoxy Composites for Structural Applications
Abstract: Composites made of carbon fibre reinforced polymer (CFRP) are currently one of the most widely used material classes in advanced engineering applications because of their remarkable environmental resistance, dimensional stability, and strength-to-weight ratio. The vacuum bag moulding method was used in this study to create CFRP laminates with different fiber-to-resin weight ratios: 50:50, 55:45, 60:40, 65:35, and 70:30. The reinforcement phase was made of unidirectional carbon fibre fabric and the …

Dissipative Particle Dynamics Simulation Study on the Evolution of Photoinitiated Free Radical Polymerization Crosslinked Networks
Abstract: Gradient polymer materials overcome the limitations of conventional homogeneous polymers by integrating multiple distinct functionalities within a single continuous structure. Although photoinitiated free-radical polymerization offers excellent spatial and temporal control, the underlying microscopic mechanisms governing network evolution under non-uniform light fields remain poorly understood. In this study, a mesoscale dissipative particle dynamics (DPD) model was successfully developed to couple free-radical polymerization kinetics—including initiation, propagation, crosslinking, and termination—with exponential light attenuation …

Structure-Property Correlation in PTT/PP Blends with Improved Mechanical Performance
Abstract: The present work investigates a series of poly (trimethylene terephthalate) (PTT)/polypropylene (PP) blends prepared with varying PP concentrations in order to improve the overall performance of PTT, particularly with respect to mechanical properties and processability. PTT is a promising engineering thermoplastic owing to its balanced stiffness, resilience, and chemical resistance; however, its relatively high cost and processing limitations often restrict its wider application. In this context, blending with PP offers …

Influence of Infill Density on Structural Performance of FDM-Processed PET-G Polymer: Experimental Validation through Quadcopter Flight Testing
Abstract: Polyethylene terephthalate glycol-modified (PET-G) is an amorphous thermoplastic copolymer increasingly adopted in structural applications through fused deposition modeling (FDM). However, the correlation between FDM processing parameters, especially infill density, and mechanical performance of PET-G parts remains inadequately characterized under real-life loading conditions. This study investigates how infill density (10% and 30%, grid pattern) influences the structural integrity of FDM-processed PET-G components, validated experimentally through quadcopter airframe fabrication and flight testing. …
