“…often represent the most suitable choice also taking into account their capability to sustain higher loads as well as their easy of assembly. In order to optimize the use of mechanical connections in composite or hybrid structures, the exploitation of the bearing behavior of pinned composite laminates has been investigated in previous papers concerning polymeric composites reinforced mainly with synthetic fibers such as glass [5][6][7][8][9][10][11] and carbon [12][13][14][15]. Furthermore, the influence of the geometrical configuration of pin-loaded composites on their bearing performances and failure modes 4 was recently investigated also for flax and glass-flax reinforced hybrid structures in our recent papers [16,17].…”

“…Vice versa: mechanical joints are easy to disassemble and able to sustain higher loads in comparison to their adhesive counterparts. Due to the common use of mechanical connections to join composite or hybrid structures, the bearing performances of pin-loaded composite laminates have been widely analyzed in the last few years by several authors [5][6][7][8].…”

The aim of the present paper is to assess the bearing performance evolution of pinned, glass-composite laminates due to environmental aging in salt-spray fog tests. Glass fibers/epoxy pinned laminates were exposed for up to 60 days in salt-spraying, foggy environmental conditions (according to ASTM B117 standard). In order to evaluate the relationship between mechanical failure mode and joint stability over increasing aging time, different single lap joints, measured by the changing hole diameter (D), laminate width (W) and hole free edge distance (E), were characterized at varying aging steps. Based on this approach, the property-structure relationship of glass-fibers/epoxy laminates was assessed under these critical environmental conditions. Furthermore, an experimental 2D failure map, clustering main failure modes in the plane E/D versus W/D ratios, was generated, and its cluster variation was analyzed at each degree of aging.

The present work aims to increase failure loads of pin joints through nanofillers and metal inserts. Pin joints were prepared from woven glass fiber-reinforced laminates with nanoclay as filler material along with metal inserts fitted in holes. To investigate the effect of nanoclay content, 1–5 wt.% of nanoclay was mixed in epoxy. The increase in tensile strength up to 3 wt.% of nanoclay was observed which was due to increase in the specific surface area of the nanocomposite material. Dispersed nanoclay filler particles act as mechanical interlocking between fiber and epoxy matrix which creates a high friction coefficient. The optimal nanoclay content of 3 wt.% was finally used to prepare nanocomposite laminates. The geometric parameters, i.e. edge distance to hole diameter (E/D) ratio and width to hole diameter (W/D) ratio were varied from 2 to 5 and 3 to 6, respectively. Progressive damage analysis along with Hashin failure criteria was performed to predict failure loads and failure modes in pin joints, numerically. Metal inserts reduced the stress concentration around the hole and redistributed stresses at the pin/hole interface, which eventually increased the ultimate failure load of the joint.
