Mechanical performance of a novel glass fiber reinforced maleic anhydride grafted polypropylene composite and its thermoplastic‐based fiber metal laminates

Abstract

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.

The influence of fiber addition and different fabrication conditions in manufacturing plasma treated polyethylene/carbon fiber composites

“…Linear low density polyethylene (Dowlex™ 2629.10UE) was used as the matrix phase and recycled carbon fibers as fillers for the improvement of mechanical properties. The matrix purchased from Dow corporate had a melt flow index and density of 3.8 g/m and 0.9370 g/cm 3 as per ASTM standards. [9] Both the matrix and filler material were not given any pre-treatment before the plasma process.…”

“…In the polymer field, polyethylene (PE) based composites have been significantly attracting the attention of researchers due to its lower cost and use in applications such as binders, electronics, battery and medical implant applications. [1][2][3][4][5] These PE matrices are combined with various reinforcements and fillers based on the applications. Fillers such as carbon fibers, glass fibers, natural fibers and carbon black improved the mechanical properties of the PE matrices.…”

Investigation of structure–flexural response relations in thermoplastic carbon/glass fiber‐metal laminates

“…Thermoplastic resins including polypropylene (PP) and polyamide 6 (PA6) have been extensively used as automobile materials with low material cost, recyclability, and high molding efficiency. 22,23 Therefore, the continuous glass fiber-reinforced PP (PP/GF) and carbon fiber-reinforced PA6 (PA6/CF) are excellent candidates for the development of thermoplastic fiber-metal hybrid laminates. [24][25][26] In general, metal sheets possess better ductility while the fiber-reinforced composite layers show a higher strength.…”

Investigating the influence of plasma treated polyethylene powder, carbon fibers in enhancing the mechanical properties of polymer composites using rotomoulding method

“…The trend is now changing toward cost effective production of polymer composites. [ 3,4 ] Polyethylene (PE) is a highly used thermoplastic due to its toughness, low coefficient of friction, reduced water absorption rate, high resistivity and ease of fabrication. [ 5 ] These polymers are used in the manufacture of sheets, insulation, pipes and container boxes.…”
