   Sammanfattning : Microwave curing has become a trend in composite processing due to its efficiency in energy consumption compared to the traditional curing method. However, as commonly found in every composite processing, controlling the microwave curing process remains challenging. The most feasible control method is to build a numerical model. LÄS MER

3. 2. Bond Strength and Degree of Conversion of Self-Adhesive Resin Cements

   Uppsats för yrkesexamina på avancerad nivå, Umeå universitet/Tandläkarutbildning

4. 3. Investigation of consolidation of stacked prepreg during robot forming

   Master-uppsats, KTH/Lättkonstruktioner

   Författare :Erik Flogvall; [2014]
   Nyckelord :;

   Sammanfattning : The purpose of this thesis was to investigate consolidation performed robotically of stacked epoxy pre-impregnated carbon ber. Consolidation is when the composite is compacted by applying pressure. This removes voids in the composite which increases mechanical properties. The process of consolidation is generally assumed to be viscoelastic. LÄS MER
