“…Their combined effect, known as hydrothermal aging, can be more damaging to the mechanical properties of the composites than to either component alone 1. Some efforts have been focused on the hydrothermal behavior of thermoplastic composites 2–5. The presence of hydroxyl groups in wood flour is available for interaction with water molecules by hydrogen bonding 6.…”

ABSTRACT:The moisture absorption and mechanical properties of wood flour-filled polypropylene composites in a hydrothermal environment have been studied by immersing the composites in water at 23, 60, and 100°C. The degree of moisture absorption was found to be dependent on the modification of matrix, the weight percentage, mesh size, and surface treatment of wood flours. It increased with increasing the immersion temperature. The tensile strength of all composites with wood flours of different contents, mesh sizes, and surface treatments increased after immersion in water baths of various temperatures, to either greater or lesser extents. The flexural strength and modulus followed a similar trend when immersed in water at ambient temperature. However, the contrary was true for composites when immersed in 60 and 100°C water baths. The impact strength increased after immersion in water at each immersion temperature, and the extent of such increment decreased with increasing the immersion temperature.

The long‐term durability of polymer composites serviced under moist, high‐temperature conditions is a major concern in many industries. As an attempt, we filled 0.3 wt % graphene in a fiber–matrix interfacial region between glass fibers, carbon fibers, glass–carbon hybrid fibers, and epoxy resin to enhance the mechanical performance of the composites under water‐immersion conditions. The mass increment was recorded periodically while the specimens were immersed in 25 and 70°C water. Axial compression tests were carried out to investigate the initiation behavior of the interfacial radial microcracks after immersion. The results show that the equilibrium moisture content and permeability of the graphene‐filled interfaces were larger than that of the virgin specimens. The interfacial radial crack initial stress decreased sharply after immersion; however, the addition of graphene in the fiber–matrix interface help to decrease this tendency in 70°C water. The observed rough surfaces of the graphene‐coated fibers after breakage in the compression tests verified the feasibility of this method. © 2018 Wiley Periodicals, Inc. J. Appl. Polym.

Improving the fire resistance of polymer and construction materials is an urgent requirement today. This article aims to study the incorporation of Polybutylene terephthalate (PBT), a versatile polymer used in most glass fiber (GF) combination fields, to study their fire resistance and impact resistance for manufacturing battery housings. We conducted injection molding and scanning electrode microscopy (SEM) and had the expected results. The impact strength of PBT/GF samples measured according to ASTM D256 is 4.69, 4.43, 3.71, 4.67, and 6.28 kJ/m2. The PBT/25% GF sample achieved the highest average impact range of 6.28 kJ/m2. The suitable GF content in the mixture is from 20–30%. Combined with SEM microstructure, it was found that the content and density of GF distribution have a positive effect on the mixture, making the bond between them remarkably tight and robust. Thanks to the property of GF, which is non-flammable, it makes the material more effective fire resistant. This research is the basis for scientific developments that help solve the problem of impact resistance of this new plastic in production and is a premise for other research purposes in the future.
