Title: Integrating tough Antheraea pernyi silk and strong carbon fibres for impact-critical structural composites

Abstract

Abstract High stiffness and strength carbon fibres are commonly used to reinforce epoxy-resin composites. While wild Antheraea pernyi silk fibres exhibit high toughness originating from their α-helix/random coil conformation structures and their micro-fibre morphology, their insufficient strength and stiffness hinders them from being used in similar structural composites. In this work, we use interply hybridization of silk and carbon fibres to reinforce epoxy-matrix composites. With increased carbon fibre content, the quasi-static tensile/flexural stiffness and strength increases following the rule of mixtures while more silk fibre acts to increase ductility and impact strength. This results in a composite comprising equal volumes of carbon and silk fibres achieving an impact strength of 98 kJ m ⁻² , which is twice that of purely carbon-fibre reinforced composites (44 kJ m ⁻² ). This work shows tough natural silk fibres and strong synthetic fibres can be successfully integrated into epoxy-resin composites for tailored mechanical properties.

Enhancing the Mechanical Toughness of Epoxy-Resin Composites Using Natural Silk Reinforcements

Journal Article Yang, Kang ; Wu, Sujun ; Guan, Juan ; ... - Scientific Reports

Strong and tough epoxy composites are developed using a less-studied fibre reinforcement, that of natural silk. Two common but structurally distinct silks from the domestic B. mori/Bm and the wild A. pernyi/Ap silkworms are selected in fabric forms. We show that the toughening effects on silk-epoxy composites or SFRPs are dependent on the silk species and the volume fraction of silk. Both silks enhance the room-temperature tensile and flexural mechanical properties of the composite, whereas the more resilient Ap silk shows a more pronounced toughening effect and a lower critical reinforcement volume for the brittle-ductile transition. Specifically, our 60 vol.%more »« less

Structural Comparison of Various Silkworm Silks: An Insight into the Structure–Property Relationship

Journal Article Guo, Chengchen ; Zhang, Jin ; Jordan, Jacob S. ; ... - Biomacromolecules

Silkworm silk has attracted considerable attention in recent years due to its excellent mechanical properties, biocompatibility, and promising applications in biomedical sector. However, a clear understanding of the molecular structure and the relationship between the excellent mechanical properties and the silk protein sequences are still lacking. This study carries out a thorough comparative structural analysis of silk fibers of four silkworm species (Bombyx mori, Antheraea pernyi, Samia cynthia ricini, and Antheraea assamensis). A combination of characterization techniques including scanning electron microscopy, mechanical test, synchrotron X-ray diffraction, Fourier transform infrared spectroscopy (FTIR), and NMR spectroscopy was applied to investigate the morphologies,more »« less

Sustainable Alternative Composites Using Waste Vegetable Oil Based Resins

Journal Article Fernandes, Felipe C. ; Kirwan, Kerry ; Wilson, Peter R. ; ... - Journal of Polymers and the Environment

Laminates were produced with epoxy resins from waste vegetable oil (WVO) intended for the manufacturing of environmentally-friendly alternatives for the composites industry. Post-use cooking oil appears a promising source of triglycerides for polymer manufacturing. Matrices cured with methylhexahydrophthalic anhydride (MHHPA) were reinforced with glass and flax fibres, creating a library of composites that were compared to analogues from virgin oil and benchmarked against commercial diglycidyl ether of bisphenol A (DGEBA). Glass fibre-reinforced composites presented Young’s moduli similar to the benchmark but reduced tensile strength. Chemical pre-treatment of the flax fibre (NaOH and stearic acid) countered the limited tensile performance observedmore »« less

Deformation micromechanisms in polymeric matrices and carbon of fibre-reinforced composites

Miscellaneous Chakachery, E A

The objective of this study is to identify the deformation micromechanisms operative in carbon fibre reinforced polymer composites and in the base polymers that act as the matrix material. The aim is to understand the reasons for the low delamination toughness encountered in the composites, and add to the knowledge required to attempt a rational synthesis of tougher composites. The focus is on micromechanisms of deformation and fracture in both matrix and composite, and in correlating these to the macroscopic fracture toughness. Fracture toughness tests, fractography and in situ crack observations in the scanning electron microscope were the main toolsmore »« less
Interface modification during oxidation of a glass-ceramic matrix/SiC fibre composite

Conference Daniel, A M ; Martin-Meizoso, A ; Plucknett, K P ; ...

Oxidation heat treatments between 375{degrees}C and 600{degrees}C for 100 hours in air, have been performed on the calcium aluminosilicate glass-ceramic matrix/SiC fibre reinforced composite CAS/Nicalon (manufactured by Coming, USA). Using a commercial nano-indentation system to perform fibre push-down tests, the fibre-matrix interfacial debond fracture surface energy (G{sub i}) and frictional shear stress ({tau}) have been determined. Modification of interface properties, compared to the as fabricated material, was observed at heat treatment temperatures as low as 375{degrees}C, where a significant drop in G{sub i} and an increase in {tau} were recorded. With 450{degrees}C, 525{degrees}C and 600{degrees}C heat treatments, an increase inmore »« less
