“…The addition of more than one type of reinforcement may improve specific properties, reducing the detriments of each reinforcement, for example, the high stiffness carbon fiber (CF) can recompense for the glass fiber's (GF) low mechanical resistance, which can lead to better flexural performance and at a marginally higher cost. [30][31][32][33][34][35][36][37][38] These FRP composites reinforced with more than one type of fibers are known as hybrid composites, as defined by Swolfs et al [30,[39][40][41] CF has excellent strength and stiffness when compared to GF. [30,[42][43][44] However, GF benefits from significantly lesser price, an important economic factor for mass production in industries.…”

Even though laminated FRP composites show exceptional performance in various modes of loading, they are susceptible to delamination. The ambient temperature and elevated temperature delamination resistance of glass/carbon fiber interply hybrid composites were assessed via mode I and mode II interlaminar fracture toughness tests performed at 30, 50 and 70 C. Interply hybrid composites performed better than composites with single type of fiber. The fracture toughness of inter-ply hybrid composites varied with the stacking position. At 30 C, mode I fracture toughness value of alternative glass and carbon fiber stacking sequence (G 1 C 1 ) 5 of hybrid composite showed 40% improvement over 10 layered carbon/epoxy (C 10 ) composite. Further, Mode II fracture toughness of C 5 G 5 composite showed 22% enhancement, and C 10 exhibited 42% improvement over 10-layered glass/epoxy composite. Increasing the test temperature of all composites improved their G IC and G IIC values. The increment in the mode I fracture toughness properties of all composite was in the range of 5%-23% at 70 C from its room temperature value. The fractographic images of fractured samples were studied under a scanning electron microscope and failure mechanisms of composites were identified.

The epoxy/acid anhydride system was toughened with a homogeneous solution of surface-treated nano-SiO2 and polyethylene glycol (PEG), which satisfies the specific requirements of wet winding processes and effectively enhances the performance of resin and carbon fiber composites at ultra-low temperatures (108K). The results show that when the uniform solution formed by 1 phr SiO2 and 10 phr PEG is added, the tensile strength and elongation at break of the modified resin were increased by 21.4% and 16.1%, respectively, at room temperature. At 108K, the strength and modulus of the modified resin were increased, and the elongation at break was 2.8%. The fracture morphology was analyzed and compared at both room temperature and ultra-low temperature, verifying the relationship between material structure and properties across different temperatures. These findings offer both theoretical and empirical backing for the development of ultra-low temperature carbon fiber composite gas storage tanks.

The rising demand for thermosetting polymers has resulted in the production of large amounts of industrial waste. Environmental issues due to waste landfills and increased raw material costs for new product development have led to the development of innovative recycling methods. This study focuses on the development of a product (helmet shell) by reinforcing thermosetting polymer waste (TPW) as a filler in a high-density polyethylene (HDPE) matrix. The HDPE and TPW were converted into extrudates using a twin-screw extruder. Then, the extrudate was pelletized to use as raw material for the injection molding machine. The HDPE/TPW composites were fabricated using injection molding. Maleic anhydride-grafted polyethylene was employed as a compatibilizer. In the composite, the TPW volume was reinforced at various weight percentages, ranging from 0 to 35 wt%. The mechanical, thermal, and viscoelastic properties of the composites can be enhanced by uniformly dispersing TPW in the HDPE matrix. However, it is difficult to achieve uniform dispersion at higher TPW volumes owing to the agglomeration effect. According to these findings, the mechanical properties were enhanced by up to 30 wt% addition of TPW. The findings suggest that the proposed composite has sufficient mechanical properties to be suitable for the fabrication of helmet shells.
