GFRPCFRP

GFRPCFRP, or glass fiber reinforced polymer–carbon fiber reinforced polymer, refers to a class of hybrid composite materials that combine glass fiber reinforced polymer (GFRP) and carbon fiber reinforced polymer (CFRP) within a single polymer matrix. By integrating both fiber types, GFRPCFRP aims to balance performance and cost, taking advantage of the stiffness and strength of carbon fibers with the toughness and lower cost of glass fibers.

Manufacture typically involves laminating layers of GFRP and CFRP in a chosen sequence, using prepregs or dry fibers saturated with resin and cured in an autoclave or resin transfer molding setup. Matrix systems commonly include epoxy, vinyl ester, or polyester resins. The layup can be symmetric or asymmetric, with the arrangement tailored to achieve specific stiffness, strength, and damage tolerance characteristics.

Properties of GFRPCFRP depend on the fiber layout and resin system. Carbon layers contribute high stiffness and strength, while glass layers provide improved impact resistance and cost efficiency. The hybridization allows tuning of bending stiffness, interlaminar shear strength, and fatigue behavior. However, benefits are highly dependent on the bonding between layers and the precautionary management of potential delamination, residual stresses, and thermal expansion mismatch.

Applications span aerospace components, automotive structural parts, sporting goods, and wind turbine blades, where a combination of light weight, stiffness, and cost effectiveness is advantageous. Design and fabrication require careful consideration of layup topology, resin cure cycles, and quality control to ensure consistent performance.

Overall, GFRPCFRP represents a flexible approach to composite design, enabling targeted property optimization through hybrid reinforcement while managing production costs.
