Fibre reinforcement in heat-cured, microwave-cured and visible light-cured base resins

open access: yesJournal of Materials Science: Materials in Medicine, 1991
The mechanical properties at transverse deflection, bending and impact tests were examined in three fibre reinforced resins including reinforcing materials such as inorganic glass fibre and cloth, organic Kevlar fibre and combined fibres. Both heat-cured and microwave-cured reinforced materials had almost the similar pattern to the changes in the ...
