The strengthening and repair of existing structures using bonded carbon fiber reinforced polymer, CFRP, laminates has attracted a great deal of attention in the past two decades. Investigations clearly indicate the great potential of this method for restoring the capacity of corroded steel beams and improving their fatigue life. One important issue regarding the use of this technique in strengt...

Fibre metal laminates, hybrid composite materials built up from interlaced layers of thin metals and fibre reinforced adhesives, are future-proof used in the production passenger aircraft, yachts, sailplanes, racing cars, sports equipment. The most commercially available fibre–metal laminates carbon aluminium aramid glass laminates. This review emphasises developing technologies for forming met...

Hybrid composites become popular and are today used in a large number of contemporary structural applications. When compared to non-hybrid composites, hybridization offers additional benefits since the mixing cheaper, low-quality fibers, with more expensive fibers higher quality can improve properties composite without significantly affecting cost. Among improvements resulted from is fatigue be...

-Dynamic delamination of thick fiber reinforced polymeric matrix composite laminates is investigated using optical techniques and high-speed photography. The laminates used in this work are graphite/epoxy fiber reinforced, 65 percent fiber volume fraction, composite plates consisting of 48 plies (6 mm plate thickness). Two different laminate layups are tested: a quasi-isotropic arrangement and ...

Pre-consolidated fiber-reinforced thermoplastic laminates often need a secondary manufacturing step such as welding, forming. When low pressure is applied during the laminate heating stage, porosities can appear in various forms (bubbles, delaminations, etc.). This deconsolidation phenomenon. These significantly deteriorate mechanical properties of composites. Usually, characterized by analysis...

This study presents a novel method to describe the microscale phenomenon of cracks initiation based on sensitivity analysis in laminate fiber-reinforced composites. The failure composite laminates often roots fiber/matrix interfacial debonding. micro-cracking and debonding composites are difficult detect both experimentally numerically. paper shows that stress response transverse ply with respe...

Abstract Forming limit curve (FLC) is a valuable tool for predicting the formability of materials. Considering need to develop FLC fiber metal laminates (FMLs), Glare in 2/1 sequence was prepared development FLC. The prepreg used glass stacked between aluminum sheets semi-cured state, which allows enhanced strain percentage and helps predict maximum forming Glare. experimental data accumulated ...
