“…It is clear that usage of jute instead of glass or carbon fiber is economic. There is a great potential for cost reduction of energy absorbing devices through many strategies, including the use of natural fibers . In this study, the cost ratio was calculated as the specific absorbed energy divided by the cost of the tube (fiber and matrix based on the supplier recommendations).…”

This article provides an experimental investigation into the crashworthiness of carbon–jute–glass reinforced epoxy circular composite tubes. The test specimens were fabricated of 6 layers with different stacking sequence using wet‐wrapping process and tested under uniaxial quasi‐static compression loading up to complete crushing. The effects of hybrid reinforcement, stacking sequence, and relative reinforcement amounts on the energy absorption capabilities and failure modes were studied. Also, the crush load–displacement response, initial crushing failure load, total energy absorption, specific energy absorption, average crushing load, and crushing force efficiency were determined and discussed. The scanning electron microscope study was considered to analyze the failure modes of the crushed specimens. Results indicate that specimens' failure modes and energy absorption capabilities were highly dominated by the reinforcement combinations and plies stacking sequence. Also, hybrid carbon–jute–glass reinforced epoxy composite tubes have the potential to be used as energy absorbers as compared to jute‐reinforced epoxy composite tubes. The JGC composite tube has a higher load carrying capacity and energy absorption capability compared to other hybrid composite tubes, so it seems to be the best appropriate choice for energy absorbing devices.

Improvement of the impact and crack resistance of epoxy thermosets and thermoset-based composites with the use of thermoplastics as modifiers

2016

Main methods for the modification of epoxy composites that aim to increase their impact and crack resistances are considered with the main attention focused on modification with the use of thermally stable thermoplastics as additives. The influence of various factors (the modifier-matrix chemical bond and the morphology and molecular weight of the modifier) on the physicomechanical characteristics of the composites is discussed. New approaches to the toughening of polymeric composite materials based on epoxy thermosets that involve the use of modified binders or the introduction of a modifier between layers of the composite prepreg are advanced.

Basalt-Fiber-Reinforced Polyvinyl Acetate Resin: A Coating for Ductile Plywood Panels

et al. 2019

The aim of this study was to create a reinforced composite wood-based panel that would be leaned towards the environment Plywood was used as a core material and fiber-reinforced polymer was used as a reinforcement. Conventional resin for the fiber-reinforced polymer was substituted with polyvinyl acetate (PVAC), which has several advantages, such as a lower price, easier handling, and better degradability. The second chosen component, basalt fiber, is cost attractive and environmentally friendly. The combination of one and two layers of fabric with three fiber fractions and 4 mm thick plywood was investigated. The best results were achieved with two layers of fabric and the highest fiber fraction. The improvements of the ultimate bending load and bending stiffness of the plywood in the perpendicular direction were 305% and 325%, respectively. The ultimate load and stiffness of the parallel direction were improved by 31% and 35%, respectively. However, specimens always failed in the compressional zone. The highest reinforcing effect was found with the impact test: The energy required to fracture specimens increased by 4213% and 6150% for one and two layers of fabric, respectively. In conclusion, specimens exhibited high ductility due to the PVAC and basalt fiber. The amount of work and energy required to cause fractures was extensive.
