Abstract
A flow medium for assisting a resin to be transferred into a mold accommodating a layered structure of reinforced material is provided. The flow medium is configured such that when the resin is cured the flow medium becomes incorporated within a final composite component comprising the reinforced material embedded within the transferred and cured resin. A semifinished product comprising such a flow medium is provided and a method for producing a composite component by utilizing such a semifinished product is also provided.
Claims17
A flow medium comprising a degradable material configured for assisting a resin to be transferred into a mold accommodating a layered structure of reinforced material, wherein the flow medium comprises a composition selected such that when the resin is cured in the presence of the flow medium, the flow medium degrades and becomes incorporated within a final composite component comprising the reinforced material embedded within the transferred and cured resin, wherein the flow medium further comprises adhesiveness with respect to the reinforced material.
A flow medium, comprising:
- a degradable material configured as a mesh structure effective to assist a resin transfer into a mold containing the flow medium and a reinforcement material;
- wherein the flow medium further comprises an adhesiveness with respect to the reinforcement material;
- and
- wherein the degradable material comprises a composition such that, when the resin is cured within the mold in the presence of the degradable material, the degradable material degrades to lose its mesh structure and to become incorporated within the resin.
