  • For example a tree is composed from cellulose fibers in a matrix of lignin (a natural resin). The strength of wood is higher “along the grain” which defines the general direction of the cellulose fibers and it is weaker “across the grain”. Splitting a piece of wood along the grain is much easier because one just has to fracture the lignin matrix which is much weaker than the cellulose fibers. The most common man-made composites are composed of glass or carbon fiber in a& ...

  • Hybrid composites are made by incorporating two or more different types of fillers in a single matrix that is highly tailorable. carbon fiber (CF) reinforced compo- sites have been well developed for certain industries such as aerospace and sporting goods. However, the high cost of carbon fiber, as well as lack of cost effec- tive processing technologies for mass production, pre- vents its penetration to many different markets. Wood fiber (WF), an environmentally sustainable bio-fiber,.


  • Recent studies have proven that wood and wood-based materials reinforced with fiber-reinforced polymer (FRP) composites are promising materials for construction applications, especially for structural members. However, there are concerns about the long-term performance of carbon FRP wood hybrid materials, the durability of carbon fiber reinforcement when subjected to environmental conditions and wood preservatives, as well as the carbon FRP wood interface susceptibility to& ...

  • Materials scientists at Harvard University have created lightweight cellular composites via 3D printing. These fiber-reinforced epoxy composites mimic the structure and performance of balsa wood. Because the fiber fillers align along the printing direction, their local orientation can be exquisitely controlled. These 3D composites may be useful for wind turbine, automotive and aerospace applications, where high stiffness- and strength-to-weight ratios are needed.
