Bioresorbable Engineering Nanocomposites for Healthcare (BENcH)
Project: Integrated Molecular Design of Melt-processable Bioresorbable Engineering Nanocomposites for Health-Care (BENcH)
This project will deliver novel, integrated methodologies for the design and scalable manufacture of next generation resorbable polymer nanocomposites, linking the science and engineering principles which underpin successful processing of such materials.
In situ polymerisation of bioresorbable composites
Project: In-situ polymerisation of fully bioresorbable polycaprolactone/phosphate glass fibre composites: In vitro degradation and mechanical properties.
Fully bioresorbable composites have been investigated in order to replace metal implant plates used for hard tissue repair. Retention of the composite mechanical properties within a physiological environment has been shown to be significantly affected due to loss of the integrity of the fibre/matrix interface.

Resorbable fibre textile manufacture
Project: Manufacture of Yarns and Textiles from Novel Resorbable Phosphate Based Glasses
Researcher: Yunqi Wang
Developing resorbable composites for medical applications - investigating the production of yarns and textiles from novel phosphate-glass fibres (PGF) with new and novel coating agents. Current single filament fibre production drastically limits the use of PGF as they cannot be re-wound and, as such, are limited in terms of architecture produced – typically only non-woven random fibre mats.
- Manufacture and characterize phosphate-based glasses (PBG) and fibres at the facilities
- Investigate the TexGen software, which will be used for modelling of textiles.
- Demonstrate the advantages of utilising PGFs as replacements for silicate based glasses by developing textiles from fibres produced utilising a pilot scale plant (Sinoma Ltd).
- The proposed fibre pilot plant facility has the potential to complete the missing link in the supply chain for low energy cost, high-strength, fully resorbable PGF technical textiles.
The Advanced Materials Research Group - Project Summary
Production of commercially scalable multifilament phosphate fibre tows
Funder: Innovate UK
Lead Participant: Glass Technology Services Limited
The aim of this project is to create a working prototype of a phosphate fibre production facility. Phosphate fibres can dissolve in water to produce materials that are present in the bones and are useful in treating damaged and broken bones. Creation of this production facility will provide the phosphate fibres in a form that can be used to make fabrics and this will be demonstrated by one of the project partners. Fabrics are much more convenient to handle than fibres alone and can be transformed into other products, such as reinforced plastics. These plastics can also dissolve in water and be applied in medicine, but also in other industries where the ability to dissolve in water would be of benefit. For example, recycling is a key issue for the future.
