Overview and aspects of the european technical specification CEN/TS 19101:2022,...
Correia, João R.; Ascione, Luigi; Keller, Thomas; Mottram, Toby; Sena-Cruz, José; Paulotto, Carlo; Knippers, Jan; Pacheco, JoãoIn November 2022, the European Committee for Standardization (CEN) published the Technical Specification CEN/TS 19101:2022, “Design of Fibre-Polymer Composite Structures.” These design provisions, which follow the philosophy and partial factor format of the Eurocodes, are a milestone toward the widespread application of composite materials in civil engineering structures. This paper presents an overview and hig...
Acoustic behaviour of GFRP-PUR web-core composite sandwich panels
Proença, Miguel; Santos, Pedro; Godinho, Luís; Neves e Sousa, Albano; Correia, João R.; Garrido, Mário; Sena-Cruz, JoséThis paper presents an experimental and analytical study about the sound insulation of innovative sandwich panels - named EasyFloor – _for the rehabilitation of degraded timber floors in old buildings. Two types of panels were developed: (i) an all-composite sandwich panel, made of glass fibre reinforced polymer (GFRP) face sheets and webs, and polyurethane (PUR) foam; (ii) and a hybrid sandwich panel, where th...
Freeze-thaw durability of vacuum infused glass fibre composites with unsaturate...
Hasan, Tarikul; Correia, João R.; Garrido, Mário; Soares, Francisco; Cabral-Fonseca, Susana; Jorge, Marco; Sena-Cruz, JoséThis paper presents an experimental study about the effects of freeze-thaw cycles (FTC) on the mechanical and thermomechanical properties of glass-fibre reinforced polymer composite laminates produced by vacuum infusion using two different polymer resins: unsaturated polyester (UP) and vinyl ester (VE). Following preconditioning in distilled water for 30 days at 20 ◦C, the composites were subjected to 100, 200 ...
Multi-objective optimization of pultruded composite sandwich panels for buildin...
Garrido, Mário; Madeira, JFA; Proença, M.; Correia, J. R.Composite sandwich panels are being increasingly considered for civil engineering structural applications, offering high versatility in constituent materials and their geometrical arrangement. This translates to a high number of design variables, in addition to a potentially large number of design requirements and objectives related to the panels' functions. This paper presents an optimization study of a compos...
