“…In contrast, Hu et al [43] states that the aging of biopolymer composites is a chemical and physical interaction process where water molecules were adsorbed physically by both the matrix and fibres, and were absorbed chemically by polymer molecules. Irreversible weight gain after aging observed in [43] in jute fibre/PLA composites subjected to hygrothermal environment can be attributed to the chemical reaction between water and PLA that results in water molecules being permanently absorbed by PLA and transformed into hydrolytic products. This hydrolysis process of PLA resulted in molecular chain breakage and caused decrease in strength.…”

“…For short to medium term protection, polymer coatings can be applied to reduce moisture absorption [10]. Short jute fiber/PLA composite was coated with 0.1 mm thick polypropylene plastic adhesive tape and subjected to hygrothermal environment [43]. In this it has been observed that at the end of the tests, fewer microcracks have occurred in the coated sample with lower moisture absorption rate.…”

A review on the degradability of polymeric composites based on natural fibres

The applications of natural fibre/polymer composites in civil engineering are mostly concentrated on non-load bearing indoor components due to its vulnerability to environmental attack. This paper evaluates the characteristics of several natural fibre composites exposed to moisture, thermal, fire, and ultraviolet degradation through an extensive literature review. The effects of chemical additives such as fibre treatments, fire retardants and UV stabilizers are also addressed. Based on the evaluation conducted, optimum fibre content provides strength in a polymer composite but it also becomes an entry point for moisture attack. Several fibre treatments are also being used to improve fibre/matrix interface, thereby increasing moisture durability. However, the treated fibres were found to behave poorly when exposed to weather. The addition of UV stabilizers and fire retardants are suggested to enhance outdoor and fire performance of natural fibre/polymer composite but compromises its strength. Therefore, from the collected data and various experimental results, it was concluded that an optimum blend ratio of chemical additives must be employed to achieve a balance between strength and durability requirements for natural fibre composites.

Natural source-based composites became promising substitutes and synthetic petrochemical-based counterparts. So far, thermoplastic starch and lignocellulosic fibers are the most common materials for making such eco-friendly "green" materials. Low cost, abundance, and renewability are the factors that lead to deploying these two types of materials. In this chapter, we are conducting further analysis for previously published results of six types of high-content natural fiber-reinforced starch-based composites. All composites were prepared by compression molding under pressure from 5 to 20 MPa and temperature from 130 to 160°C. Composites exhibited highest tensile strength and modulus of elasticity at fiber weight content from 50 to 70%, and then mechanical properties deteriorated significantly at 80% fiber content due to the insufficient starch resin. For instance, the tensile strength was boosted up from 2-12 MPa for thermoplastic starch to reach 55,45,32,28,44, 365 MPa for flax, bagasse, date palm fiber (DPF), banana, bamboo, and hemp composites, when fiber content was increased from 0% to the optimum fiber content (50-70%). Kelly-Tyson (random 2d) was the optimum model to predict random fiber composite. Increasing the fiber content and choosing a fiber with high cellulose content significantly improve the moisture resistance of the composites. Fick's law of diffusion predicted the water uptake property successfully. The thermal stability of composites was improved with increasing the fiber weight content as well. This is attributed to the high thermal stability of cellulose when compared to starch. Properties exhibited by starch-based high-content natural fiber composite are promising for many industrial and biomedical applications.

“…The interface between fiber and matrix can also easily influenced by moisture absorption because matrix is easy to absorb water which leads to volume expansion, while carbon is almost non-absorbent, so that the resin's swelling generates stress and can cause interface deboning [7,8].In addition, water could interrupt the chemical bonding of the matrix or the interface, and could change the network structure of the matrix, hereby degrading material performance [9,10].The high temperature is another important factor leading the degradation of mechanical properties [11,12]. Rue-Hua Hu's study indicates tensile strength of composite laminate severely decreased when exposed to hydrothermal condition [13].Zhuang Huawei investigates compressive strength of open hole laminate under high temperature [14].Peng Lei suggested that the tensile and compressive strength and stiffness of open hole laminates decrease in hydrothermal conditions [15].…”

Abstract. This study investigates the effects of environmental factors on tensile properties of laminated composites containing a central hole. Tensile tests were carried out on three types of specimens that are exposed to low temperature, room temperature and hydrothermal environment respectively. Tensile experiments were performed according to the ASTM D 5766. The results of moisture absorption tests indicated that the saturated moisture content of the specimens was around 0.7% after 1200 hours. Tensile tests results showed that the tensile strength, stiffness and fail strain of open hole increased with the content of 0° fiber, the tensile strength and stiffness increased in low temperature environment and decreased in hydrothermal environment.
