Design and Control of Laying Sequence for Mechanical and Impact Properties of Carbon Fiber Flax Fiber Hybrid Composite Materials

Research Overview: A study published in Volume 547 of Construction and Building Materials (November 14, 2026) was conducted by S. Dharani Kumar, Gaurav Arora, Sanjay Mavinkere Rangappa, and Suchart Siengchin. The study focused on regulating the mechanical and impact behavior of carbon fiber linen fiber hybrid composites through layer sequence design. This study belongs to the field of composite material performance and design research in the field of building materials, focusing on the influence of fiber layer arrangement on the final mechanical performance.

Core focus

Research focuses on the hybrid system of carbon fiber and flax fiber.

. Carbon fiber provides high stiffness and strength, while flax fiber, as a natural fiber, brings different density, toughness, and sustainable properties. When the two are mixed in the same composite material, the stacking order of each layer of fibers will change the load transmission path, interlayer stress distribution, and absorption of impact energy. Therefore, the stacking order becomes a key design variable for regulating the overall performance. From the title and source information, it can be confirmed that the research investigates the influence of layer sequence design on mechanical and impact behavior, which belongs to the work of material properties and processing design. This type of research has reference value for composite material components that need to balance load-bearing, impact resistance, and lightweight in the fields of architecture and home decoration, such as the selection and layer design of building templates, decorative components, and some structural profiles.

Significance for the polymer additive industry

Although the research focuses on fiber hybrid composite materials rather than directly targeting polymer additives, its conclusions have extended significance for the design ideas of building and home decoration materials.

. Composite materials also face requirements for weather resistance and stability under outdoor or long-term use conditions; Combining antioxidants and light stabilizers in resin matrix is a common method to delay material aging and maintain mechanical properties. For building materials represented by PVC profiles, weather stability is one of the core indicators in formula design. The selection of antioxidants and light stabilizers directly affects the color retention and impact toughness retention of the profiles. The concept of “structural design regulation performance” reflected in the layering sequence also suggests that the formulation design of additives needs to be considered in conjunction with material structure and processing methods. In fiber hybrid composite materials, the stability of interlayer interface and resin matrix will affect the damage propagation after impact; In applications such as PVC profiles, pipes, and building coatings, the matching of additive systems also determines the performance of materials under long-term loads and climate conditions. This study provides academic reference for understanding the relationship between fiber arrangement and performance in the field of building materials, and indirectly emphasizes the necessity of viewing weather stability and mechanical properties from the perspective of overall material design.
