“…Then the impact energy absorption due to single delamination per unit area of composites is expressed as follows. (6) In this study, the interlaminar shear strength was estimated by the short beam shear test results of Figure 7. The interlaminar shear modulus G 13 was estimated using Chamis results [31], which was expressed as function of fiber volume fraction v f , fiber shear modulus G f and matrix shear modulus G m as follows.…”

The impact energy absorption characteristics of glass epoxy composites and glass polyester composites with respect to fiber volume fraction were investigated by the instrumented Charpy impact test method. Also, the interlaminar shear properties were measured by the short beam shear test to investigate the correlation between the interlaminar shear properties and the impact energy absorption characteristics. Appropriate curing cycle was suggested for polyester resin by measuring the dissipation factor. Using the experimental results, the impact absorption characteristics of glass fiber composites such as fiber breakage and fiber pull-out and delamination were discussed.

“…In both examples or in many others that it is possible to report (as machine tool columns with improved stiffness 12 or an anthropomorphic robot for an efficient handling 13 ), this change in materials regards the selection of a totally different one, typically from metals to reinforced plastics. 14 But, such action also implies, sometimes, a change of paradigm in design.…”

This paper analyzes the possibility to substitute the gray iron, traditionally used for the production of relevant parts in woodworking machines, with ductile iron or vermicular iron. A large experimental campaign to determine the mechanical beavior of ductile and vermicular irons respect to tensile, fatigue, and fracture loads was conducted and the microstructures were also analyzed. Results show that ductile or vermicular cast iron in parts and components of machine tools could provide additional stiffness and resistance for the high precision woodworking respect to Gray Iron. A balanced utilization of these alternative irons would permit to take a full advantage by each specific property (as strength, hardness, weight, etc.).

“…As such, the structural integrity depends critically on the joint performance and not just on the basic composite structure. 1 Multiple experimental studies and simulations have investigated the failure of different types of joints, including composites to composites [2][3][4][5][6][7][8][9] and composites to other materials. [10][11][12][13][14] In adhesive-bonding situations, initial cracking usually occurs around overlapping ends due to stress concentrations.…”

Two novel joints made from partially un-moulded carbon-fibre-reinforced plastic plates were designed to increase the strength of joints between carbon-fibre-reinforced plastic parts. In the partially un-moulded plate, a portion of the fabric stack was moulded with resin while the rest of the fabric stack remained dry. The plate was made using a manufacturing process developed from vacuum-assisted resin-transfer moulding. A new double-lap joint sandwiched a normal carbonfibre-reinforced plastic plate between the dry fabric layers of a partially un-moulded plate. The other laminated joint overlapped the dry fabric layers of two partially un-moulded plates. Both joints were moulded by resin transfer. Tensile testing indicated that the two novel joints were more than twice as strong as a classical double-lap joint and half as strong as a normal, joint-free carbon-fibre-reinforced plastic plate. Additionally, the joints may potentially be made much stronger by modifying their shapes. In particular, the laminated joint may be made as strong as a normal carbon-fibrereinforced plastic plate because its strength is determined by the fibre-matrix interface rather than the bondline strength, which is a key factor in determining the strength of a normal carbon-fibre-reinforced plastic plate.
