Abstract

Overbraiding is used as a reinforcement in two example systems. This includes both standard and ‘fuzzy’ overbraids, the latter created by braiding a brittle fibre at short lay length over a central component; when incorporated into a fibre-reinforced composite increases the resin-matrix contact zone. The fuzzy aspect is therefore expected to improve structural performance.
Hierarchical composites, inspired by nature, can be created using pultruded rods as an element, with a hierarchy of fibres at the shorter length scale forming rods at the medium scale and a larger structure then created from these rods. Overbraiding of the pultruded rods is shown to improve their performance under compression.
Microvascular channels, used for cooling, can be created in a composite laminate through a lost poly(lactic acid) process. Overbraiding of the poly(lactic acid) results in reinforced microvascular channels, with a fuzzy carbon overbraid demonstrating an order of magnitude increase in burst pressure of the microvascular channels compared to the unreinforced case.
