Abstract Joints obtained by resistance welding of polyphenylene sulphide (PPS) laminates reinforced with bidirectional glass fiber (GF) fabrics were investigated by fractographic analyses. The welded joints were tested under lap shear loading at room temperature. The fracture surfaces were analyzed by scanning electron microscopy (SEM) technique. Electric resistance welding technique uses the matrix flow property, when the thermoplastic is heated above the softening temperature (for amorphous po...

This study aims to reuse the waste of uncured composite prepreg scraps from the ply cutting manufacturing process in the aerospace industry, avoiding the resin loss, waste disposal and expenses with its incineration.Carbon fiber/F155-epoxy resin laminates were produced by randomly positioned scraps, with different sizes and shapes, and characterized by tensile, compression, interlaminar shear (ILSS), and flexural tests. Tensile, compression, and flexural strengths of produced laminates decreased...

Abstract This work shows a fractographic study on fracture surfaces of welded joints by electrical resistance of thermoplastic composites based on polyphenylene sulfide (PPS) reinforced with continuous carbon fiber (CF), evaluated after lap shear loading. The fracture surfaces were generated with the complete breakdown of the specimens under the same conditions used in the mechanical test. The fractographic aspects of fracture surfaces were analyzed by scanning electron microscopy (SEM). SEM ana...

This study focuses on the evaluation of the effect of hygrothermal conditioning on tensile, compressive, in-plane and interlaminar shear properties, and also on the viscoelastic characteristics of carbon fiber/epoxy laminates. Flat unidirectional laminates were manufactured by dry filament winding and cured under hot compression. The laminates were later exposed to hygrothermal conditioning in a chamber, following the recommendations of ASTM D5229M. All composite coupons were tested before and a...

An experimental investigation of the resistance welding of PPS/carbon fiber is presented in this manuscript. Currently, one of the main problems of the structural polymer composites consists in its effective integration of the components. The electrical resistance welding has been considered as one of the promising techniques for bonding composites, because it is a quick process with easy surface preparation. To improve the process to welding poly-(phenylene sulfide) (PPS) reinforced with carbon...
