The application of natural fiber-reinforced composites is gaining interest in the automotive, aerospace, construction, and marine fields due to its advantages of being environmentally friendly and lightweight, having a low cost, and having a lower energy consumption during production. The incorporation of natural fibers with glass fiber hybrid composites may lead to some engineering and industrial applications. In this study, abaca/glass fiber composites were prepared using the vacuum-assisted resin transfer method (VARTM). The effect of different lamination stacking sequences of abaca–glass fibers on the tensile, flexural, and impact properties was evaluated. The morphological failure behavior of the fractured-tensile property was evaluated by 3D X-ray Computed Tomography and Scanning Electron Microscopy (SEM). The results of mechanical properties were mainly dependent on the volume fraction of abaca fibers, glass fibers, and the arrangement of stacking sequences in the laminates. The higher volume fraction of abaca fiber resulted in a decrease in mechanical properties causing fiber fracture, resin cracking, and fiber pullout due to poor bonding between the fibers and the matrix. The addition of glass woven roving in the composites increased the mechanical properties despite the occurrence of severe delamination between the abaca–strand mat glass fiber.

The rheological behaviour and mechanical properties of the polycarbonate/high density polyethylene/glass fiber (PC/HDPE/GF) composites have been studied, along with fiber-resin interface behaviour. Maleic anhydride grafted low density polyethylene (LDPE-g-MAH) was used as a compatibilizer in the composites. A study of the glass fiber-resin interface by scanning electron microscopy (SEM) and by etching techniques indicated that the dispersed phase polymer in the composites preferentially adhered to the glass fibers in the absence of LDPE-g-MAH. For the composites containing LDPE-g-MAH, this resin might play a decisive role in the adhesion of polymers to glass fibers. The types of adhered polymers were independent of PC/HDPE ratio. The rheological behaviour was studied using a capillary rheometer. The results showed that there was little relationship between the viscosities of the components and the types of polymer adhered to glass fibers. There was a critical shear rate at about 100s−1 for the viscosities of the composites. At shear rates lower than 100s−1, the glass fibers increased the viscosity of the composites; at shear rates higher than 100s−1, the glass fiber had little effect on the viscosity. The composites had a good balance of mechanical properties compared with PC/HDPE blends and PC/GF binary composites. LDPE-g-MAH in the composites could improve the reinforcement efficiency of the glass fibers and strengthen the adhesion between polymer matrix and glass fibers.

The utilization of carbon and glass fiber composites is very extensive in the fields of aviation and automobiles. The strength to weight fraction of these composites is immense. Even though, the modern applications require a lot of improvement in strength. The addition of Nano fillers had brought about significant changes in mechanical properties of the composites. The present work aims at finding out the effects on mechanical properties of composites due to the addition of titanium oxide 10% + silicon dioxide 10% hybrid filler. Hand layup process is used for the fabrication of tensile and flexural test specimens which are prepared as per the ASTM standards. The tensile test specimen is D-638 type-iv and the flexural specimen is D-790. Epoxy is used as resin and forms the matrix whereas the carbon and glass fibers act as reinforcement. The comparison is made between the specimens with and without hybrid filler. Two specimens of each type are prepared to have repeatability. The tensile and flexural tests are carried on universal testing machine (UTE-10) and results were obtained. The results showed a significant improvement in tensile and flexural strengths of carbon composites and only flexural strength in glass fibers with hybrid filler.
