Abstract
This work has described the production of single-polymer composites by the film-stacking method. Two types of single-polymer composites with different mass fractions of the polyester reinforcement phase (10% and 20%) and the PETG matrix were investigated. The produced composites were subsequently recycled by injection moulding, pressing, and extrusion. Selected properties of the processed composites were determined: density, viscosity-average molecular weight, impact resistance, and tensile strength. The work done in this paper has demonstrated the benefits and drawbacks of each recycling method for these materials. The selected properties of single-polymer polyester composites and single-polymer polyester composites that were recycled by extrusion have also been compared.
Highlights
This work has described the production of single-polymer composites by the film-stacking method
The problem is increasing due to gradual decommissioning of aircraft, watercraft, and wind turbine propellers that are made of laminates and so on
The term recycling refers to a recovery operation, as part of which waste materials are reprocessed to make products, materials, or substances used for the original purpose or for other purposes [4, 6,7,8]
Summary
This work has described the production of single-polymer composites by the film-stacking method. The term recycling refers to a recovery operation, as part of which waste materials are reprocessed to make products, materials, or substances used for the original purpose or for other purposes [4, 6,7,8]. Chemical recycling is the recovery of substrates used to manufacture a given article It allows the repeated application of raw materials for the production of full-value materials, and the resulting waste (heavy or light ends of petroleum) may be used as an additive to fuels or lubricants [3,4, 9,10,11]. On the other hand, during the material recycling, the product’s intended use is different from that of the original product (with lower requirements for final products)
