Abstract
A method of forming a continuous composite structure (49) includes the steps of mixing in a chamber (39) a liquid reactive resin forming material, a catalyst, an inhibitor and a particulate solid additive material in proportions based on the ambient temperature. A pool (35) of the mixture is formed on a porous blanket (34) and part is migrated therethrough prior to gelling to a continuous resin matrix therein. Opposite edges (73,74) of a preselected length (72) are grasped creating a preselected tension in the blanket length (72) which is maintained while is maintained while transferring the blanket length (72) to a final location.

A method of forming a continuous composite structure including the steps of preselecting a liquid reactive resin forming material, a catalyst, an inhibitor, a particulate solid additive material and a porous blanket, measuring ambient temperature, determining relative proportions of said resin forming material, said catalyst and said inhibitor based on said ambient temperature and said porous blanket, mixing said additive particles with said predetermined proportions of said resin forming material, said catalyst and said inhibitor substantially continuously, encapsulating substantially all of said additive particles with said catalyzed and inhibited resin forming material, forming a pool of said mixture on said blanket while it is moving over an elongated arcuate surface disposed in a preselected orientation, advancing said mixture-treated blanket while migrating part of said catalyzed and inhibited resin forming material through said blanket substantially uniformly prior to gelling of said material to form a continuous resin matrix within said blanket, grasping a leading edge of said matrix/blanket along substantiallly its entire width, advancing said leading edge away from said arcuate surface along a preselected path, grasping opposite edges of a preselected length of said matrix/blanket structure, creating a preselected tension in said structure length, maintaining said tension while transferring said structure length to a final location, depositing said structure length on a final surface while said length is flexible and adhesive, and applying pressure to form a tight bond therebetween.
Continuous structure forming apparatus including a supporting portion, a material supplying portion, a mixing portion, a matrix forming portion, a positioning portion and a control portion;
- said supporting portion including a plurality of spaced upstanding frame members, a plurality of generally horizontally disposed frame members joining adjacent upper and lower ends of said upstanding frame members;
- said material supplying portion including a plurality of reservoirs operatively connected with said supporting portion, said reservoirs being connected independently with said mixing portion;
- said mixing portion including an elongated mixing chamber adjustably disposed adjacent said supporting portion;
- said matrix forming portion including mixture distributing means extending adjustably downwardly from said mixing chamber and being disposed adjacent an outlet thereof;
- said positioning portion including a generally horizontally disposed frame section extending from said supporting portion, said positioning portion including elongated structure grasping means translatably movable along said frame section, a structure transferring assembly alignable with said frame section including structure tensioning means;
- said control portion including programmable memory means, coordinating means, sensing means, actuating means, and circuitry transmitting signals from said sensing means to said coordinating means for comparison with said memory means and activation of said actuating means to form and place a continuous structure into a preselected final configuration while it is flexible and adhesive.
