In this article, continuous glass fiber reinforced thermoplastic prepreg is proposed using maleic anhydride grafted polypropylene (MAPP) as the matrix resin. The compression molding parameters and plying sequences are optimized. Under the process parameters of 155 C and 15 MPa, both the tensile and flexural properties achieve the maximum values, and the plying sequence of (0 /90 ) possess a balanced mechanical performance. Then, MAPP/GF/Al fiber-metal laminates are further fabricated in two stacking configurations of 2/1 and 3/2. The mechanical results showed that the tensile and bending strength were basically maintained, while the modulus are significantly enhanced by 114.9% and 135.4% in 2/1 and 3/2 fiber metal laminates (FMLs) in contrast with MAPP/GF controls. In addition, the large deflection behavior in bending test for FMLs suggest that MAPP/GF and aluminum alloy show a synergy deformation due to the good bonding between metal layer and thermoplastic resin. The optical microstructure also revealed that the interlaminar adhesion are well joined between FML constituents. The findings in this study are important from a design viewpoint of FMLs because of the lower material cost, less processing time, and good lightweight effect, which potentially be tailored to use as structural parts in automobile applications.

“…Linde The model takes the ultimate strain as the criterion for damage, and believes that both the tensile and compression properties of the material are broken. The model assumes that the material has continuous damage, mainly considers the damage of the fiber and the matrix, so that the destruction process of the fiber and the matrix is described by two injuries [121,122], the matrix is expressed as:…”

With its excellent fatigue performance and high damage tolerance and other irreplaceable advantages, FMLs have gradually increased the demand in aerospace, rail transit, ship and other fields, and have put forward higher requirements for the speed and accuracy of its performance test and index evaluation. In this paper, the methods of performance test, analysis and index evaluation of FMLs are introduced from three aspects with carbon fiber and composite materials, mechanical properties and numerical simulation technology, details the common test methods, the latest technology and progress, and analyzes their advantages and disadvantages, so as to provide direction and reference for the performance test method and index evaluation of FMLs. Finally, the main development directions of the current performance testing methods and index evaluation of FMLs are briefly discussed.

Experimental and Numerical Study on Mechanical Characteristics of Aluminum/Glass Fiber Composite Laminates

The fiber-metal composites made of aluminum sheets and glass fibers reinforced with a polyester resin as the matrix were studied. The composites were prepared by hand lay-up method. Some aspects of manufacturing affecting the composite behavior were considered. In particular, the influences of the arrangement of layers and their number on the mechanical and physical properties of composites with ten different compositions were investigated. In addition two different densities of glass fibers were considered. The tensile modulus, tensile and impact strengths were determined following ASTM D3039 and ASTM D6110 standards. The results obtained show that the arrangement of the laminate layers influences Young's modulus and the tensile strength of the composite. The impact test results of the laminated structure reinforced with glass fibers illustrate a significant increase in the impact strength owing to adding the glass fibers compared to the control specimens. The simulations of tests using ABAQUS-based FEA were performed.
