The effect of glass fibre-reinforcement on the transverse strength, deflection and modulus of elasticity of repaired acrylic resins

Aim: To test the effect of reinforcement qualities of glass fibre in the repair of acrylic fractures. Methods: Four types of heat‐curing acrylic resin test specimens were fabricated. The bottom and sides of the specimens were placed in stone to form a repair template. Lines were drawn 3.5mm on each...

Description
Summary:Aim: To test the effect of reinforcement qualities of glass fibre in the repair of acrylic fractures. Methods: Four types of heat‐curing acrylic resin test specimens were fabricated. The bottom and sides of the specimens were placed in stone to form a repair template. Lines were drawn 3.5mm on each side of the centring mark. The 45 degree‐bevel joint margins were cut at these lines to simulate fracture and the centre section was discarded. A 1mm gap was created between the margins before repair with autopolymerising acrylic resin with and without glass fibre. Outcome measures: A three‐point loading test was used to measure transverse strength, deflection and the modulus of elasticity of repaired acrylic resin joints. Results: The transverse strength of acrylic resins was increased with fibres. Conclusion: Glass fibre‐reinforcement significantly increased resistance to deflection and increased the modulus of elasticity.
