“…Another advantage that stands out compared to open-mold processes is that VI has very low volatile emissions even though it uses only a one-sided mold system [11][12][13]. There are several studies on composite beams in the literature, especially box beams [14,15], but only a few have explored the benefits of using VI to manufacture this type of part, being pultrusion the most common processing technique employed for this type of component [16]. Thus, the objective of this study is to produce a hollow carbon fiber/epoxy composite box beam with a square crosssection profile by vacuum-infusion.…”

In this paper, a hollow square cross-section carbon fiber/epoxy composite beam was designed and manufactured. Evaluation of the beam behavior considered orientation and stacking sequence, aiming to reduce the number of layers and weight. Finite element method (FEM) was used to simulate the performance of the composite beam under 3-point bending and using three failure criteria, Tsai-Hill, Tsai-Wu and maximum stress. In order to identify the input parameters for the model, flat composites were tested under tension and compression. It was concluded that a minimum of 12 layers of unidirectional carbon fiber were required to reach the required load (44.5 kN). The prototype was successfully fabricated by vacuum-infusion process and subjected to 3-point bending test. The experimental failure load was within the predicted range by the Tsai-Hill failure criteria and maximum stress.

“…For example, they are relatively stronger and lighter than classical building materials such as concrete and steel [10][11][12], they are more durable than timber and require less maintenance. Especially when looking at footbridges [13,14], this type of material can offer an added value. In the context of the greening of the mobility [15,16], these bridges will make up a much more important part of the public infrastructure in the future.…”
