HexPly M9M10

Product catalog summary

Description
HexPly® M9/M10 is a versatile epoxy resin suitable for low pressure moulding processes, with processing temperatures ranging from 85 °C to 150 °C. It is ideal for large industrial components and offers high fatigue resistance and a good surface finish. Variants include HexPly® M10 for medium tack and HexPly® M9 for higher tack, used in marine, wind turbine, and industrial applications.

Benefits and Features
- Versatile cure cycle (85-150 °C)
- Suitable for thick laminates and low pressure processing
- Good surface finish and flexibility
- Excellent tack life and fatigue resistance
- High flow matrix and translucent resin after curing
- Suitable for pressures 0.3-5 bar

Resin Matrix Properties
- Tensile strength: 85 MPa
- Tensile modulus: 3.2 GPa
- Strain: 3.75%
- Flexural strength: 136 MPa
- Flexural modulus: 3.16 GPa
- Glass transition temperature: 110-135 °C
- Cured resin density: 1.2 g/cm³

Prepreg Curing Conditions
The ideal cure cycle is 60 min at 120 °C with pressure between 0.3 and 5 bar. Alternative cycles range from 85 °C for 12-16 hours to 150 °C for 10 min.

Processing Methods for Thicker Components
For components up to 10 mm thick, use internal bleed layers of dry fabric to absorb excess resin, distribute vacuum, and control fibre volume. For monolithic structures, distribute dry fabric plies evenly; for sandwich structures, distribute in the outer 2/3 of the skin.

Mechanical Properties
Various configurations of E-glass and HS carbon fabrics show tensile strengths ranging from 600 MPa to 2000 MPa and flexure strengths from 700 MPa to 1850 MPa, with fibre volume content between 50% and 60%.

Storage and Precautions
- Tack Life at 23 °C: 60 days
- Shelf Life at -18 °C: 12 months
Handle with usual precautions for synthetic resins and fibrous materials. Use clean disposable gloves to avoid contamination.

HexPly® M9/M10 Product Data What is the best cure cycle for thicker components ? To avoid exotherms it is advisable to incorporate a dwell and a controlled heat up rate. Dwell - used to equalise tool and component temperatures and to initiate a controlled prepreg cure. Controlled heat up rate - avoids a large temperature differential between the air temperature and the component. Any accumulations of resin are prone to exotherm under these conditions. Prepreg Storage Life I Tack Life @ 23 °C (73 °F) 60 days I Guaranteed Shelf Life @ -18 °C (0 °F) 12 months Precautions for Use The usual precautions...
