“…Experimentally, the absolute density of the coconut fibers tested in the present study is reported in Table 1. This result is in line with the observations already made in [13,[41][42][43]. This value is less in comparison with commonly used fibers like steel fiber (7.80 g/cm 3 ), carbon fiber (1.75 g/cm 3 ) [44], or glass fiber (2.55 g/cm 3 ) [45].…”

In order to reduce the dependency on conventional materials and negative environmental impacts, one of the main responsibilities of the construction field is to find new eco-friendly resources to replace the traditional materials partially. Natural fibers were known as potential candidates for the reinforcement of structures in civil engineering by virtue of their advantages. Among the different kinds of vegetable fibers, coconut fiber has been exploited in a limited way over the past few years. This paper aims at evaluating the different properties of local coconut fibers (Vietnam). Several laboratory tests provide geometrical, physical, mechanical properties and durability properties that are compared with literature results obtained from similar natural fibers. The local coconut fibers tested demonstrated properties suitable for reinforced mortars. With adequate control of their preparation, they could be reused in the manufacture of mortars in the construction.

“…Basically, the coconut tree trunk is characterized as a cone-shaped column with many nodes [44]. The coconut tree has many advantages that can be applied in engineering such as coconut mesocarp [45], and coconut shell [46], coconut fibers [47]. For energy absorption application, Liu et al [44] mimicked the distribution of vascular bundle in coconut tree to design bio-inspired multi-cell carbon fiber reinforced plastic and aluminum square tubes.…”

“…The toucan beak is a representative example of a sandwich composite structure consisting of superposed hexagonal scales of keratin attached to each other and a fibrous network of closed cells comprising calcium-rich proteins. Sandwich structures inspired by coconut shells have a total of three layers, known as exocarp, mesocarp, and endocarp layers from the outside to the inside [ 12 ]. The structure of coconut shells can be imitated in the design of laminated structures, with a hard outer layer for penetration resistance and a soft inner layer for increased toughness and energy absorption.…”

Inspired by many biological structures in nature, biomimetic structures demonstrate significantly better mechanical performance than traditional engineering structures. The exceptional mechanical properties of natural materials are attributed to the hierarchical architecture of their structure. Consequently, the implementation of biomimetic structures in the design of lightweight structures with tailored mechanical properties has been constantly increasing in many fields of science and engineering. The bamboo structure is of particular interest because it combines a light weight and excellent mechanical properties, often surpassing those of several engineering materials. The objective of this study was to evaluate the mechanical behavior of bamboo-inspired structures subjected to transversal compressive loading. Structures consisting of bamboo-like thin-walled hexagonal building blocks (unit cells) with different dimensions were fabricated by stereolithography 3D printing and their mechanical performance was evaluated by mechanical testing, high-speed camera video recordings, and finite element simulations. The results of the elastic modulus, yield strength, and strain energy density at fracture were interpreted in terms of characteristic dimensions of the unit cell structure. The failure process was elucidated in the light of images of the fractured structures and simulation strain maps. The results of this study demonstrate that ultralight bamboo-like structures with specific mechanical characteristics can be produced by optimizing the dimensions and number density of the hexagonal unit cell.
