Abstract
The invention provides an epoxy heating fiberglass mould and a preparation method thereof. The preparation method comprises the following steps including female mould manufacturing, mould structural manufacturing; gel coat manufacturing; topcoat manufacturing; heating layer manufacturing; structural reinforcing layer manufacturing; heat preservation layer manufacturing; framework support manufacturing; temperature control system manufacturing; and silica gel surface mould manufacturing. The epoxy heating mould meets the requirements that the high temperature deformation temperature is above 120 DEG C, the shrinking percentage is low, and heating is uniform, and the technical problem that local overheating damages the mould is solved.
Description
[0001] Technical field: [0002] The invention belongs to the field of glass fiber reinforced plastic manufacturing, and in particular relates to an epoxy heated glass fiber reinforced plastic mold and a preparation method thereof. [0003] Background technique: [0004] As the automobile industry and end customers have higher and higher requirements for automobiles, as well as high requirements for the strength and deformation of FRP in other high-end fields of composite materials, such high requirements need to be solved from at least three aspects: the first First, the problem of low shrinkage resin; second, the problem of molding process; third, the problem of curing degree during demoulding. [0005] To solve the three problems raised above, we need to start from the mold. Of course, the metal mold can best meet the above conditions. However, due to the high manufacturing cost, the products we are currently in contact with do not meet the batch manufacturing requirements o...
